The 1/2.5" sensor of the Canon PowerShot SD630 I am trying to repair. The gears look ok and I got the lens retracted. I'll try putting it back together tomorrow and see if it works. Wish me luck.
It was a close encounter with a kestrel that first ignited my passion for bird photography. They are such wonderful birds.

This may or may not be kinda badass. We've got a bunch of varmints here in Lower Alabama, and I'm curious about what skulks around in the night. This thing has 6MP resolution at its best and can be programmed to shoot one to nine shots every time the IR motion sensor is tripped. It also can do video. The flash is supposed to reach out to 50 feet, and from testing in the living room, it's bright as hell.
Too bad it doesn't shoot RAW....
I'm too tired and lazy to strap it to a tree today, but tomorrow we'll see what happens.

This is an earlier shot of my visit to the Liège railway station last month. I like the way the beams in the ceiling fan out to the left and the way the short arm of the clock points to the sun. The main shot of the day was the 12 o'clock - high noon shot.
This is probably one of the most photographed buildings in Belgium, so it is hard to find an original angle. On any given Sunday, there are at least 50 other enthusiasts walking around & shooting, photogs paradise!

To celebrate the 40th anniversary of „The Empire Strikes Back“, I designed this massive and 1 meter wide Duel on Cloud City Diorama early 2020. It depicts 2 different locations inside/outside the Gas-Processing Vane: Main Control Room and the Sensor Balcony.
This scene recreates the iconic duel between Luke and Vader starting with the Main Control Room where Luke gets sucked out of the Viewport...
Note: This was my first try in editing lighstaber effects, hope you like it!

Microscale build of the Baserunner used by Rachel S'jet in the game Homeworld: Deserts of Kharak.
From the Homeworld Wiki:
The "Baserunner" expedition support vehicle was a reliable workhorse that was used to deploy sensors, turrets, minefields, and aerial drones. The vehicle was manned by a crew of 10. Most kiiths also operated specialized variants of the baserunner such as the S'jet Science Team Baserunner
Does this count for FebRovery?

Here is a shot from December 2. It was one of the craziest burns I've seen over San Francisco. There were so many colors and stages to this sunrise that I thought my sensor might have been fried from the overload.
Wishing everyone a Happy New Year, and looking forward to shooting in 2016!
Thanks for looking!
At the moment we are in the middle of decorating and all my junk (including, as some have said, all my camera gear lol) is packed away in boxes. However I have kept some stuff out in case it is needed, I am not sure why I have included a sensor cleaning swab as I am not brave enough to mess with my camera sensor at all!
The drawer is 11 x 6 x 5 inches and the image of the entire drawer is used for 124 pictures in 2024 group theme # 46 Higgledy-piggledy. The area of the shot for MM is approx 2.75 inches square.

A very popular camera by Agfa from the late 70s and a little marvel of industrial design. The "Optima Sensor" name had been used by Agfa for a series of simple electronic consumer cameras since the late 60s denoting the presence of a big, red, feather-touch shutter button (sensor) that adorned the top of the camera and was considered very hi-tech at the time.
This last series of the Agfa Optimas were marketed during the late 70s and production continued well into the 80's being hugely successful in the european market. At least 5 different models exist, including a rangefinder (Agfa Optima 1535) and one equipped with an electronic flash, aptly named "Agfa Optima Flash". The best online source of information regarding these cameras can be found here:
www.edition-oldenburg.de/agfa_optima.html
The Optima 1035 pictured here sits second from the top of the line-up feature-wise. It is a zone-focus camera with a fully automatic exposure system based on the Agfa Paratronic electronic shutter. Despite its introduction at a time when plastic was already being used extensively in camera manufacture, the littke Agfa is mostly made of metal with a very durable black coating. Some parts are made of plastic (like the film advance lever or the focusing ring) but the overall feel is that of a solid, durable camera.
The most prominent feature of the camera is the HUGE and extremely bright viewfinder which is a small revelation for first-time users. It is very close in size and brightness to the viewfinders found in premium rangefinders and makes using the camera a real joy. In the 1035 the VF features three distance symbols and a red needle that moves between them according to the chosen focus distance, the minimum being 0.9m. The frame line is illuminated and there are parallax correction marks for close subjects.
Another unique feature of the Optima is the lack of a rewind crank. With the help of (rather flimsy) toggle switch on the top plate, the film advance lever doubles as a rewind crank, a clever design that made the installation of such a bright finder on such a small camera possible.
Upon opening the film door, another clever feature makes its apperance: When loading the camera, the film is passed under a small shield on the winding side which protects film that has already been exposed from accidental opening of the film door.
The lens is a fast f2.8, 40mm four-element Solitar-S ("S" denoting multi-coating) which is quite sharp under good lighting conditions with good contrast and resistance to flare.
Shutter speeds go up to 1/1000s and in low light the Paratronic can stay open for at least one full second. The high top shutter speed combined with the minimum diaphragm opening of f22 ensure proper exposure of fast film even under the brightest conditions. The shutter is completely battery-dependent, it doesn't open at all if batteries are not installed. The feather-touch shutter release ensures minimum shake when taking the shot, reducing the chance of a blurry shot in relatively slow speeds.
Agfa engineers were clever enough to put the CdS cells of the metering system at the six o'clock position of the lens beauty ring, a fact that prevents shadowing of the sensors when a lens hood is used.
Not everything is good on the little Agfa though. For starters, the ASA setting stops at 400 which can be quite limiting if one wants to push fast film. Also, there is no backlight compensation provision, one has to change the ASA setting to deal with backlit subjects.
Additionally (and most annoyingly) the shutter produces an awful screeching sound when fired, probably the worst-sounding shutter I've ever come across, regardless of camera type.
Another ill-conceived feature of the camera (perhaps imposed by the necessity for small size) is the fact that the battery department is accessible only after opening the film door, so in case the batteries die mid-roll, the film must be rewound in order to change them. To make things worse, there doesn't seeem to be any means of knowing if the batteries are weak. The camera uses an uncommon arrangement of three 625 button cells, but at least its exposure system is designed for the common alkaline ones, not the obsolete mercury cells.
For some reason, Agfa deemed it necessary to equip the camera with a red LED lamp that sits above the lens barrel and lights up momentarily every time the shutter is fired, letting everyone know that you've taken their picture. It also blinks during countdown when the (mechanical) self-timer is activated.
As you can see from the picture, the Optima has no strap lugs, as Agfa chose to equip the camera with a proprietary screw-on neck strap that attaches on the left side, a solution that is a complete failure in my opinion. First of all, if you lose the strap there is no way you can replace it with a generic one. Also, the choice of a long neck strap is very poor for such a small, light camera which would benefit most from a short wrist strap, although a pair of scissors and a couple of rivets can easily remedy that. On top of that, placing the wrist strap on the left side is totally counterintuitive, as it virtually precludes secure single-handed operation of the camera with the right hand. According to the manual, the port for the screw-on strap doubles as the tripod mount, although this obviously implies that the camera can be used only in vertical orientation when on a tripod.
Overall, the small size and all-black color, combined with an accurate, fully automatic exposure system, a good semi-wide lens and an unsurpassed viewfinder, make this little Agfa very attractive as a stealthy street shooter. Still, there are a few shortcomings that make it fall short of being the perfect "little black beauty" a title I reserve for the Olympus XA2, my "golden standard" for this particular category of cameras.

We are one week away from the release of the first science-quality images from NASA’s James Webb Space Telescope, but how does the observatory find, and lock onto its targets? Webb's Fine Guidance Sensor (FGS) – developed by the Canadian Space Agency was designed with this particular question in mind. Recently it captured a view of stars and galaxies that provides a tantalizing glimpse at what the telescope's science instruments will reveal in the coming weeks, months, and years.
FGS has always been capable of capturing imagery, but its primary purpose is to enable accurate science measurements and imaging with precision pointing. When it does capture imagery, it is typically not kept: given the limited communications bandwidth between L2 and Earth, Webb only sends data from up to two science instruments at a time. But during the week-long stability test in May, it occurred to the team that they could keep the imagery that was being captured because there was available data transfer bandwidth.
The engineering test image – produced during a thermal stability test in mid-May – has some rough-around-the-edges qualities to it. It was not optimized to be a science observation, rather the data were taken to test how well the telescope could stay locked onto a target, but it does hint at the power of the telescope. It carries a few hallmarks of the views Webb has produced during its postlaunch preparations. Bright stars stand out with their six, long, sharply defined diffraction spikes – an effect due to Webb's six-sided mirror segments. Beyond the stars – galaxies fill nearly the entire background.
The result – using 72 exposures over 32 hours – is among the deepest images of the universe ever taken, according to Webb scientists. When FGS' aperture is open, it is not using color filters like the other science instruments – meaning it is impossible to study the age of the galaxies in this image with the rigor needed for scientific analysis. But: Even when capturing unplanned imagery during a test, FGS is capable of producing stunning views of the cosmos.
“With the Webb telescope achieving better than expected image quality, early in commissioning we intentionally defocused the guiders by a small amount to help ensure they met their performance requirements. When this image was taken, I was thrilled to clearly see all the detailed structure in these faint galaxies. Given what we now know is possible with deep broad-band guider images, perhaps such images, taken in parallel with other observations where feasible, could prove scientifically useful in the future,” said Neil Rowlands, program scientist for Webb’s Fine Guidance Sensor, at Honeywell Aerospace

This image: This Fine Guidance Sensor image was acquired in parallel with NIRCam imaging of the star HD147980 over a period of 8 days at the beginning of May. This image represents a total of 32 hours of exposure time at several overlapping pointings of the Guider 2 channel. The observations were not optimized for detection of faint objects, but nevertheless the image captures extremely faint objects and is, for now, the deepest image of the infrared sky. The unfiltered wavelength response of the guider, from 0.6 to 5 micrometers, helps provide this extreme sensitivity. The image is mono-chromatic and is displayed in false color with white-yellow-orange-red representing the progression from brightest to dimmest. The bright star (at 9.3 magnitude) on the right hand edge is 2MASS 16235798+2826079. There are only a handful of stars in this image – distinguished by their diffraction spikes. The rest of the objects are thousands of faint galaxies, some in the nearby universe, but many, many more in the high redshift universe.

this is a result of my faulty card reader... a happy accident since I was able to re-import without the digital damage.
"The North Point Light Station has a long history of guiding mariners to Milwaukee. Its location was chosen to mark the north point of Milwaukee Bay. Erected in 1887 and first lit in 1888, the 39-foot octagonal cast-iron tower replaced an 1855 cream-city brick lighthouse built too close to the eroding bluff. The Queen Anne - style keeper's dwelling was built at the same time. In 1912 the tower was almost doubled to its present height of 74 feet by lifting the existing tower atop a new structure. This resulted in a light source 154 feet feet above the level of Lake Michigan visible up to 20 miles away."
[The lighthouse was deactivated in 1994.] "In 2003 the two-acre property was transferred to Milwaukee County. The North Point Lighthouse Friends and Milwaukee County completed restoration of the light station on 2007."

Couple of the best features of mirrorless are IBIS and a dual-gain sensor, a boon to handheld night photography.
In post-processing such images, my aim is to preserve the contrast of the bright vs the dark areas. All too often night images appear flat and lifeless from overzealous pushing of highlights recovery and shadow lifting.
Got the iPhone 15 Pro Max recently as my iPhone 11 Pro Max died abruptly after successfully completing an IOS update.
Just like cameras, there’s no need to buy into every newly released iteration, IMO skipping 3 or even 4 iterations is fine these days, less waste for the planet besides.
This is the 1st time I got to play with Apple’s ProRAW and in particular 48mp ProRAW Max. New stuffs in iPhone 15 Pro Max are; 1) 24mp photo mode, 2) 48mp HEIF Max and ProRAW Max, 3) Night mode in 16-bit color space, 4) 5x camera and 5) Action button.
1) 24mp photo mode
==================
From dpreview;
“Using Apple’s Photonic Engine technology, the camera captures multiple versions of a scene that are optimized for different things, such as light capture, noise removal, color fidelity, subject awareness and so on. It then compresses those images into a single layer. What the iPhone 15 series adds is another computational step, combining that optimized result with a 48MP image to add detail, resulting in the default 24MP image.”
This much advertised new 24mp mode, it’s limited ONLY to the 1x Main camera (ie not on 0.5x, 2x or 5x) with further limitations when using Night mode, Macro, Flash or Portrait Lighting which can only be saved at 12mp. Tapping on the 1x icon toggles to the 1.2x (28mm) and 1.5x (35mm) cropped modes. We do get 24mp with the 1.2x and 1.5x crop mode from the main 1x camera but 2x crop yields only 12mp. The greater the crop, the smaller the file size even as resolution remains unchanged.
I’m really not happy with the 12mp limitation for Flash and Macro shots even though I can understand this helps with better noise performance (pixel-binning) for Night mode. The current Sony A7SIII is still only 12mp even though A7RV is 61mp. iPhone cameras have no physical variable aperture control hence Macro shot are not stopped down for greater DOF (like in ILC cameras) which will result in loss of light so I can’t see why Macro mode needs to default to 12mp especially if focus stacking is used without the ability/need to stop down the aperture. My old iPhone 11 Pro Max could focus at close subject distances even though it did not have a “dedicated” Macro mode, in iPhone 15 Pro Max, at similar close distances, it can’t even focus until you invoke the Macro mode, what gives? Imagine your 48mp premium camera can only take 12mp images when you attach a Macro lens, how is this acceptable!? (See postscript (1) below).
2) 48mp output
==============
ProRAW files are in uncompressed 12bit DNG file format. ProRAW is unlike our typical camera RAW, this is an Apple creation in collaboration with Adobe. ProRAW is a demosiaced file that stores results of computational photography right inside the RAW. Apple avoids sloppy demosaic algorithms in third-party programs or apps by doing this step themselves, which makes Apple's DNG file already different from one you'd get out of a DSLR.
Unedited 48mp ProRAW Max files seem to look a little soft almost as if lacking critical focus, the files can be pushed quite a lot and do take (in fact require) a lot of sharpening compared to the HEIF files. These 48mp ProRAW Max files are around 60+mb (apparently can go up to 100mb!) vs 5mp HEIF Max, the size difference is more than 10x. High time Apple introduces lossless compression to their ProRAW files. The 61mp Sony A7R5 lossless compressed RAW is 83.1mb vs 133.7mb uncompressed. The 42mp Sony A7R2/A7R3 has lossy compressed RAW at 43mb vs 83mb uncompressed so 48mp ProRAW at 60-100mb is just ridiculous for a smartphone. Simple editing of 60+mb ProRAW Max files on the iPhone, clicking “save” has a bit of lag.
Fortunately there is also an on-screen HEIF Max=>RAW12=>RAW Max toggle.
In summary, 48mp ProRAW Max or HEIF Max or 24mp HEIF are only available to the 1x camera because only this main 1x camera has the quad-Bayer sensor. 1.2x and 1.5x cropped from the 1x camera will also produce 24mp HEIF but ProRAW is 35mp for 1.2x and 24mp for 1.5x. The 2x cropped only produces 12mp files. Apple up-scale the 1.2x and 1.5x photos to maintain the 24mp output. Quad-Bayer sensor first appeared on iPhone 14 Pro models.
3) Night mode in 16-bit color space
==============================
I can’t see any difference indoors, will have to try some outdoors night shots soon.
4) 5x camera
===========
The new 5x (120mm) camera has 3-axis sensor-shift stabilization, I believe the 1x is stabilized at 2-axis only and the 0.5x has no stabilization? Sensor-shift stabilization first appeared in the iPhone 12 Pro Max, lens-based stabilization was the previous standard, just like DSLR to Mirrorless cameras.
This new 120mm equivalent tetraprism camera is useful, the screen appeared nicely stabilized to compose the shot and the results are crisp.
[Postscript: The 5x camera’s native aperture is f2.8 but can be adjusted post shot to simulate f1.4 if “Portrait” mode is turned on.]
5) Action button
==============
IMO best use of the new “Action” button is to assign it to “Camera” which not only allows us to invoke camera in locked screen but also as shutter/record button, it’s a little more instantaneous then the camera icon in locked screen.
A couple of personal takeaways;
============================
1. Always backup your phone before updating the software and have it plugged in to a power source while updating,
2. ProRAW is great and in particular 48mp ProRaw Max enabled by the quad-Bayer sensor. This is a real step in the right direction to turn smartphones into viable cameras. Just like in cameras, RAW files will not look good compared to JPEG/HEIF. Apple ProRAW files do respond to edits well and can be pushed further than HEIF files, more importantly ProRAW can and should take a lot of sharpening to look like HEIF/JPEG from iPhones. Apple will need to upgrade its in-phone “Photos” app editor IMO to better exploit the 48mp ProRAW Max files.
Yet to try;
1. Portrait “faux-keh”,
2. Night mode with new 16-bit color space for outdoors.
Future evolution? I’m listing out important features I hope to see in future iPhone iterations, will skip each iteration until Apple makes the iPhone I desire, or until my current phone dies whichever comes first.
1. True optical telephoto zoom lens,
2. High-resolution photos in all modes including Macro and Flash modes at least on the main 1x camera,
3. High-resolution for the 0.5x ultra-wide camera,
4. Lossless compression for ProRAW Max files,
5. Manual settings allowing users control shutter speed, ISO, sensor-shift stabilization on/off. As it is, we already get EV control & AF/AE lock on iPhones,
6. 1 touch White Balance adjustment like the way Ricoh GR does it.
7. Tripod-based pixel-shift high resolution mode at Base ISO.
8. Better “Photos” app with selective post-processing capability.
9. Dual-slot backup; with external SSD, if file is large 48mp ProRAW Max, the phone should retain a 12 or 24mp HEIF file.
Postscript
=========
1) iPhone 11 Pro Max 1x main camera sensor size is 1/2.55” while the 15 Pro Max is 1/1.28” which explains for the worse minimum focus distance for the newest phone. iPhone 15 Pro Max has to switch to its 0.5x ultra-wide camera for Macro, this 0.5x camera sensor has the same size and resolution as the 1x in the iPhone 11 Pro Max at 1/2.55” 12mp hence Macro mode on iPhone 15 Pro Max drops to 12mp. IMO the so called “Macro mode” is kinda bogus!
2) Found yet another limitation to the 24mp and 48mp modes on the 1x (incl 1.2x & 1.5x) camera. If 16:9 widescreen format is selected, output resolution drops to 36mp from the original 48mp.
3) 5x camera with native f2.8 aperture can simulate f1.4 post shot when Portrait mode is turned on.
