This morning, on Hawk Hill - much less foggy than yesterday!
A 27-or-so exposure HDR panorama, processed in Photomatix and Photoshop. The tone-mapped HDR processing was only used sparingly in certain places, where necessary - it's mostly RAW data.
These direct-sun HDR panoramas are about as difficult to capture well as anything, but I think I'm starting to get it down pretty well these days. This one took about 3 hours to process.
I've been experimenting with a new technique to get more detail with less noise - this upload on flickr, though admittedly reduced from the 70-megapixel original, has had zero noise reduction applied, and seems pretty noise-free to my eyes. So, it seems to be working so far.
Minolta DiMAGE 7 CCD-Chip.
2/3"-type interline primary-color CCD with a total of 5.24 megapixel (with a 4.92 megapixel effective resolution; 2560 x 1920).(Sony ICX282)
Mount Ötscher, the highest mountain in Lower Austria, seen from St.Leonhard.
Taken in October 2007, this is one of my earliest digital efforts altogether. It was taken with my first digital camera - a PENTAX OPTIO L30 compact point & shoot (7 megapixels) - which I had bought to send an urgently needed photo by e-mail. I'm rather fond of this scene, with the tempting red apples, so I'm glad to have the chance to share it on flickr!
Cardboard object, close-up, contre-jour. Edited in Fuji's raw converter and refined and cropped in Luminar.
Shot in front of the iconic neon lights over the lakes in Copenhagen (søerne).
I used the super cool Fotodiox Rhinocam adapter, it enables you to take a super high resoltion photos using your Fuji/Sony/Canon/Nikon camera and a medium format lens. I used the cheap and very good Mamiya Sektor C 80mm f2.8 lens. The Rhinocam gives you 8 images that you then stitch together in software (I used PtGui Pro). Original photo was 160 megapixel but I cropped it a bit to 132 megapixels. Read my full review of the Fotodiox Rhinocam here

While looking for macro subjects on the trail a grasshopper jumped away as soon as he noticed me. I grab the camera and went after him, but it took me a lot of time to get a clear view and a good angle. When I went back on my walk I realize that I'm the real young grasshopper jumping around not knowing the full powers and magic of the Florida woodlands.
(Spanish): Fábula del Bosques de Florida (Pequeño saltamontes).
Mientras buscaba sujetos para mis fotos vi un saltamontes saltar en la vereda, pues había notado mi presencia. Tome la cámara y me fui a tomar le una foto. Lo cual resulto difícil ya que no se quedaba quieto. Cuando volvi a mi caminata me puse a pensar que yo soy el verdadero pequeño saltamontes en este maravilloso y mágico bosque).

Large zoom-able 53 Megapixel map of the view from the Mont-Royal observing point of down town Montreal.
18000x6000, 110 megapixel 9 panel panorama stitched using PTGui Pro.
The panorama features Dragon Hill, the Giants Stair and the Manger with the Shires of Oxfordshire and Wiltshire in the background.
Dragon Hill is a natural chalk hill with an artificial flat-top which legend has it, that it was upon this summit that Saint George slew the dragon.
The visible bare patch of chalk on the summit - which no grass will grow - is purported to be where the dragon's blood spilled.
The Giant's Stair are ice-cut terraces caused by glaciation during the last ice age.
The Manger is the meadow located between the foot of The Giant's Stair and Dragon Hill. In local folklore, legend has it that the Uffington White Horse feeds on the Manger at night.
Clevedon Pier is a seaside pier in the town of Clevedon, Somerset, England on the east shore of the Severn Estuary. It was described by Sir John Betjeman, as "the most beautiful pier in England"
These colours were already there, I just slid the saturation bar a tiny bit for Sliders Sunday. I used my 11yr old Panasonic and Raynox macro lens to take this pic which is only a 10 megapixel camera so quality might be grainy. I love all the colours ..... maybe just maybe summer is nearly here!
Happy Sliders Sunday to you all and have a great week ahead! :-))))
Once, Gizmo was fairly popular on Flickr and in the Furry Fridays group.
I ran across this shot (taken in 2008) while checking out photos that were taken with my starter camera, the Canon Powershot, A510. I was a dandy little 3.2 megapixel point and shoot.
Since I had just moved up to the Canon Rebel XTi, this could possibly be the last time I used the A510.

Mimosa pudica also called sensitive plant, sleepy plant, action plant, touch-me-not, Mimosa Strigillosa, sunshine mimosa, and powderpuff. Is a creeping annual or perennial flowering plant in Southern USA, the compound leaves fold inward and droop when touched or shaken, defending themselves from harm, and re-open a few minutes later. Also attracts butterflies and serves as a host plant for butterfly larvae; and an effective ground cover because it spreads very quickly
(Spanish): Esta curiosa planta de America, cuando se toca o pisa, automáticamente se envuelve para protegerse y luego se abre unos minutos después. Siempre que la veo la toco para ver como de mueve).

With so much beauty around me, I couldn't fit it all in view in just one shot... Even at 14mm...!!! I stitched this together from 10, 12 or so shots at 38mm using a Nikon D750 and Photoshop CC. This panorama is nearly a whopping 19000 px across by over 5000 in height. A massive 102 megapixels that would print at over 5ft wide at 300 dpi...!!!
Parrot creation gone slightly awry - i'd have a word with the top man, or maybe his mum and dad ! :-)
Old Nikon D40 image resurrected from the archive and given a genetic modification in the photo lab - who uses 6 megapixels nowadays anyway?
Il est vrai qu'une image de 48 mégapixels prise par un iPhone ou tout autre smartphone n'est pas aussi nette qu'une image de 48 mégapixels prise par un appareil photo à objectif interchangeable plein format !!!
Des choses fondamentalement différentes se produisent avec un smartphone et un appareil photo plein format, ce qui a un impact sur la qualité de l'image !
L'une des différences les plus importantes réside dans la technologie du capteur lui-même. Étant donné que le capteur d'un smartphone est beaucoup plus petit qu'un capteur d'image Micro Four Thirds, APS-C ou plein format, de nombreux smartphones récents, dont l'iPhone 16 Pro, utilisent ce que l'on appelle un capteur d'image Quad Bayer.
En tant que photographes, nous aimons comparer les spécifications et les performances, mais nous savons depuis toujours que les mégapixels ne sont pas un indicateur fiable de la qualité de l'appareil photo. Ce n'est même pas un indicateur de résolution : la résolution des détails dépend des attributs et paramètres de l'objectif et de l'appareil photo ! »
« Les gens utilisent [l'appareil photo 48 mégapixels de l'iPhone] tous les jours et obtiennent des photos de plus haute résolution avec plus de détails !
Est-ce que le pouvoir de résolution est le même qu'un appareil photo plein format ? Probablement pas. Mais c'est comme comparer une pomme à une orange 🤔
De toute évidence, un appareil photo plein format doté d'un objectif dédié et d'une optique de grande taille spécialement conçue produit des images de meilleure qualité qu'un appareil photo de smartphone. Et tout aussi évidemment, je pense que ce n'est pas parce qu'un smartphone crée une image de 48 mégapixels qu'il sera en mesure de concurrencer favorablement un appareil photo plein format de 48 mégapixels. La taille du capteur, et donc la taille des pixels, ont un impact considérable sur la qualité de l'image !!!
°°°°°°°°°°°°°
A 48-megapixel image from an iPhone or any smartphone doesn’t look as sharp as a 48-megapixel image from a full-frame interchangeable lens camera is accurate !!!
Fundamentally different things happen with a smartphone versus a full-frame camera that impact how good an image looks !
One of the most significant differences is the sensor technology itself. Since a smartphone sensor is much smaller than a Micro Four Thirds, APS-C, or full-frame image sensor, many of the latest smartphones, including the iPhone 16 Pro, use what’s called a Quad Bayer image sensor.
“I think as photographers, we enjoy comparing specs and outputs, but we’ve always known that megapixels are not a reliable indicator of camera quality. It’s not even an indicator of resolution — resolving detail comes down to the lens and camera attributes and parameters!”
“People use [the 48-megapixel iPhone camera] every day and get higher resolution shots with more detail !
Whether it’s the same resolving power as a full-frame camera ? Probably not. But that’s comparing an Apple to an orange 🤔
Obviously a full-frame camera with a dedicated lens with large, specially-designed optics produces better-quality images than a smartphone camera. And just as obviously, I’d have thought, just because a smartphone creates a 48-megapixel image doesn’t mean it will compete favorably against a 48-megapixel full-frame camera. Sensor size, and thus pixel size, dramatically impacts image quality !!!

Les mégapixels plus élevés coûtent plus cher et les appareils photo prestigieux coûtent encore plus cher.
Je pense qu'il est également important de souligner que tous les photographes n'ont pas besoin ou même ne souhaitent pas un nombre très élevé de mégapixels, mais cela semble être l'option qui vous reste.
Je ne veux pas transmettre le message que seuls les appareils photo plus spécialisés ci-dessus sont adaptés à la photographie.
Mais si vous voulez un appareil photo plus abordable avec des niveaux de résolution plus raisonnables, il sera par défaut conçu pour plaire à un plus grand nombre d'acheteurs potentiels et les fabricants s'efforceront sans aucun doute de rendre ces appareils aussi polyvalents que possible.
Cela signifie que vous obtiendrez un appareil photo avec au moins un niveau assez élevé mis sur les performances vidéo.
En vérité, les fonctions vidéo d'un appareil photo doivent être présentes, car chaque appareil photo numérique moderne envoie un signal vidéo vers l'écran LCD et le viseur électronique. L'idée est que vous pourriez tout aussi bien avoir la possibilité d'enregistrer ce flux.
Même le Leica M11-D extrait un signal vidéo du capteur au cas où quelqu'un voudrait y placer le viseur électronique Visoflex. C'est pour cette raison même qu'il ne coûtera pas moins cher au consommateur d'ignorer simplement les aspects vidéo d'un appareil photo. Il est logique d'offrir à la fois des photos de haute qualité et des fonctions vidéo d'un point de vue purement pratique, à moins que l'appareil photo ne soit conçu pour être très spécialisé. Comme nous l'avons vu, cela tend également à signifier très cher 🤔
°°°°°°°°°°°°°
Higher megapixels cost more money and prestigious cameras cost even more than that.
I think it’s also important to point out that not all photographers need or even desire really high numbers of megapixels, but that seems to be what you’re left with as your option. I don’t want to convey the message that only the more niche cameras above are suited for photography.
But if you want a more affordable camera with more reasonable levels of resolution it will by default be designed to appeal to a more substantial pool of potential buyers and the manufacturers will undoubtedly endeavor to make those cameras as versatile as possible.
That means you are going to get a camera with at least a fair level of emphasis being placed on video performance.
Truthfully, the video features of a camera have to be there regardless because every modern digital camera outputs a video signal to the LCD panel and EVF. The idea is that you might as well have the option to record that feed.
Even the Leica M11-D is pulling a video signal off of the sensor in case someone wants to put the Visoflex EVF on it. It’s for this very reason that it won’t cost any less money to the consumer to simply ignore the video aspects of a camera. It makes sense to offer both high-quality stills and video features from a purely practical perspective unless the camera is designed to be very niche or very specialized. As we’ve seen now though, that tends to also mean very expensive 😉
P.S : - De nombreux appareils photo intègrent désormais des capteurs superposés qui offrent de grands avantages à la fois pour la vidéo et la photographie de sport/action. Cependant, les compromis pour obtenir cette vitesse supplémentaire nuisent souvent à la plage dynamique. Ce seul point fait du Z7 II l'appareil idéal pour l'utilisateur Nikon qui n'a pas besoin des dernières nouveautés en matière de vidéo 😉
°°°°°°°°°
P.S : - Many cameras are now incorporating stacked sensors which give big benefits for both video and sports/action photography. However, the compromises to get that extra speed often hurts dynamic range. This fact alone makes the Z7 II ideal for the Nikon user who doesn’t need the latest and greatest when it comes to video 😉

One of my favorite spots which i visit again from time to time.
I shot a pano using six vertical shots and blended them together. The final cropped image has 110 megapixels - and no- it's none of this >100 megapixel rubbish that you can get out of your mobile phone nowadays.
f/11 1sec
I first started photographing birds in 2003. I bought a new Canon 10D from B&H which I think was around 10 megapixels with practically no low light capabilities, laborious shutter fire, minimum buffer size and hit or miss high speed auto focus. I drove all the way to Canoga Camera in Los Angeles from Grants Pass, OR to buy my Canon 400mm f5.6 lens because I wanted to try it out first. It is still a great lens in 2018.
Regardless, I was able to get some pretty decent images many of which I printed and sealed in protective plastic wrap. Thank goodness I did because I knew nothing about file preservation and did not keep any of the raw originals, duplicate files or make external hard drive back ups. I corrupted all the images by not paying attention to size and quality while processing.
It was a painful lesson considering all the hours I put in walking down the Rogue River in hip waders before dawn. Sometimes I would force my way through dense thickets and stand for hours in a slough waiting for one chance at a Night Heron or Green Heron. I even got flight shots of Herons and Osprey with fish. I don't know how I did it because 7 years later, when I took the hobby up again, I missed flight shot after flight shot. The only solution was to upgrade to the Canon 7D.
I knew that Summer Lake, Oregon had a large wildlife population because I had lived and worked there in the 70s and 80s. In 2016, I came across an ad for a house, garage and small acreage. I jumped at the opportunity. Leaving a house and job behind in Bend, OR, I find myself back where I started. Only now, I have the awesome Canon 7D mark II and a 150-600mm Sigma Lens along with other assorted camera gear.
When I first moved to Summer Lake in 74 I had a Minolta SLR in which I used mostly black and white film. It was inconceivable that a photographic image like the one above could have ever been possible. The advances in wildlife photography since those prehistorical days are incredible. Currently I have no goals other than to play around and see what comes of it. Oh yes, and eagerly await the next technological breakthrough.
More chicanery from ipad software showing another scene from down town Corfu.
Sony Alpha 100 ....10 megapixels.....must of shot 12,000 images with this over a period of two years.
90-photo multi-row HDR panorama. 31,200 x 16,300. (508.5 megapixels.)
Was hoping to catch sunset but it ended up being total overcast. Overcast isn't terrible though, it gave me an even lighting situation to work with.

Oh lord. This was quite a chore to process. Lightroom has a maximum filesize of 512 megapixels. I learned this fact tonight because it wouldn't stitch any of my panos from Horseshoe Bend. No, it didn't tell me why. When this scene was merged, the photo was larger than 512 megapixels. You would think that LR would say this, but instead it just says that I need to choose another projection method.
Another problem is that the extreme depth of Horseshoe bend causes further issues with LR's projection modes. I guess that even if it had been under 512 megapixels, it still wouldn't have worked.
Alas, I had to fork over $300 for PTGui.
PTGui is able to import my raw CR3 files and can even merge HDR, but it doesn't really have any good features to adjust images or set a camera color profile, so my first attempt came out looking bland.
So I started over for the 15th time. I went into LR and individually merged each of the thirty HDR images manually. I processed a few to see which settings would work the best, then set all images to have an identical treatment (color balance, exposure, contrast, highlight, etc.)
Exported these thirty completed images as TIFFs, stitched with PTGui (equirectangular projection), and exported a massive 980 megapixel photo (half of which was empty space). I couldn't import that it LR because it was over the 512mp maximum, which is how I learned about the maximum. If I had been holding a stack of papers, I would have tossed them into the air at this point.
So, I opened it in Photoshop and cropped it down to what I needed. Every slice of the crop tool hurt. I finally managed to crop it down to a reasonable size without losing any key detail or breaking composition. Saved the changes.
At this point, I noticed that PTGui lost all of my exif data. So I used my exiftool to copy the exif data from one of the original files and overwrite the settings on the pano TIFF. (Yes, really - this story is still going.)
Finally successfully imported into Lightroom. From here, I edited it with DeNoise AI to bring out some incredible sharpness. Denoise has the MOST INCREDIBLE sharpening I have ever seen. It gets in there, even on these massive panos, and sharpens the tiniest details. It makes them look wonderful at Max Zoom.
Back into Lightroom with the sharper image. I did my tone curve adjustments and a slight clarity adjustment and then it was time to get it uploaded.
THANK YOU FOR LOOKING AT THIS. I HOPE IT WAS WORTH IT.

While visiting a wilderness area, notice this lizard eating something inside the curled leaves of a small tree. He was having a feast from leaf to leaf. When close inspecting what he was eating, find out it was aphids. Really small insects that you will not be able to see with your eyes. But also notice that some ants were running too fast and crazy. Watching the ants, find out that they were attending the aphids and when coming back and not being able to find them in a specific leaf; they will go nuts discovering that their aphids are gone. Love lizards, they always take care of most problematic insects.
(Spanish): Mientras visitaba un parque, note una lagartija comiendo de hoja en hoja. No podia ver lo que comía, pero inspeccionando bien lo que comía, encontré que eran áfidos o casi microscópicos pulgones. No se pueden ver bien a simple vista de tan pequeños. Pero también me di cuenta que habían hormigas corriendo como locas. Tome tiempo en observarlas y me recordé que ellas atienden los afidos ya que secreta un nectar y cuando regresaban y no las encontraban; se volvían como locas brincando desesperadas. Yo defiendo a las lagartijas ya que nos protegen las plantas y devoran insectos molestosos).

6 megapixel camera by Leica that really gives some surprizing results...usual pixel thrashing going on here...!
This is our first light image using the new QHY600 60 Megapixel Full Frame Monochrome CMOS camera mounted on the Takahashi 130 FSQ, I want to thank QHYCCD for the honor to be testing this amazing new camera. The image was captured in RGB, Ha and OIII. (H-Alpha is mapped to Red channel @70% opacity, OIII is mapped to the blue channel @70% opacity and OIII is mapped to the green channel @50% opacity) The Optolong OIII filter produces halos on the bright stars in this image such as 52 Cygni which is a bit disappointing however I'll be using Chroma Narrowband Filters on this setup from the end of this month.
Pictured here to the left of the image covering an area over 3 x 2 degrees of sky of are the Eastern Veil Nebula NGC6992 to the Western Veil Nebula NGC6960 (Witch’s Broom) far right with “Pickering’s Triangle” in between at the top of the image as well as “The Funnel” just below and the many knot’s and strands visible here and within this beautiful Supernova remnant.

The dim constellation Monoceros, just east of Orion, hosts yet another majestic star factory. The Rosette Nebula, a vast wreath of gas and dust with a cluster of new stars near its center, is not associated with the Orion Molecular cloud but lies further along the Orion Arm of the Milky Way.
The Rosette has an apparent size similar to the Orion Nebula. But at a distance of 5,000 light years, it’s three times farther than the Orion Nebula, which means it’s intrinsically three times larger, spanning a diameter of about 115 light years.

The California Nebula Captured recently in color (LRGB) using the new QHY600 60 Megapixel Full Frame Monochrome CMOS camera mounted on the Takahashi 130 FSQ that we have the honor of testing for QHYCCD.
This time around mainly due to a lack of clear nights lately I decided to capture the LRGB binned 2x2 for 2 minute exposures so I can capture the data quickly, H-Alpha data that I had captured previously at 1x1 binning was then added to the red channel and as a luminance layer during post processing in photoshop.
I was more than pleased with the results as I found with the 2x2 binning and 4788x3194 pixels there was no if any loss of resolution or detail when using on the TAK. Binning at 2x2 increases the pixel size to 7.5um pixels and full well capacity is increased to 196ke.

(Press "L" or Click on the image for a Larger View).
Trumpet Vine (Campsis radicans), native to the eastern United States, its magnificent flowers never fail to attract Hummingbirds. This image was taken with a 21-year-old, 3 Megapixel DSLR camera, the Canon D30. Was the first Canon-made digital SLR. Very impressed by the resolution, colors, and exposure latitude. The JPG is soft but the raw files are fantastic. For example, I underexpose this shot by almost 2 stops, and the editor was able to recover the exposure with no noise. I have been using this camera for only two days, and already love it.
(Spanish): Una flor nativa del este y norte de EU, que atrae mucho a los colibrí o chuparrosas. Esta foto la tome con la Canon D30. La primera cámara DSLR hecha completamente por Canon. Solo tiene 3 megapixeles pero su calidad de imagen es estupenda. Por ejemplo esta foto por error la expuse 2 pasos por debajo de lo correcto. Creía que no lograría rescatarla, y fácilmente en el editor pude recuperar la exposición sin ruido).
