I am working out my screen calibration on a new monitor. The monochrome picture above looks fine on my new screen but has a lot of contrast when viewed on my old system. Let me know if there are dart blue toned areas on the stem and upper corner. I did not intend this picture to be as heavy handed as it is when viewed on my old (put correctly calibrated screen). I may need to do some further adjustments to my new system. BW is about tone - you have to be able to control the tone.

One from late last year - checking calibration of monito(s) again - any comments appreciated - does this look right brightness wise / white point / colours? Thanks
So this rant is about monitor calibration and colour management etc....
So I took this picture using a Hoya ND8 filter and a Hitech ND8 graduated filter. The filters add a bit of colour cast to the image, but shooting in RAW this can easily be corrected.
My computer has 2 monitors attached to it, these both show the image in completely different colours! OK so that may be an exaggeration, but one is a lot more saturated and contrasty than the other. Another 'variable' I have found is the program in which the picture is viewed. Photoshop/Picasa/Windows Photo Viewer all seem to show the image with slightly different colours.
Now this might not matter to most people, but it is starting to drive me crazy, especially when I think my photo is being finished with nice vibrant colours only to find out on another screen it looks pretty dull!
I think it may be time to invest in a screen calibrator. Has anyone on here had much luck with them?

Thanks!
This is a shot of Crewe station, dive in and explore it, there's lots to see......or so you would think. Of course, there is always a train in Crewe station, isn't there ? On this occasion when i launched my drone to do this aerial study i expected to get a light streak of a Pendolino racing through the station but....nothing.
I was in the car park of what i consider to be the worst Premier Inn in the country, the one where you have to walk through an industrial estate to get there. It doesn't have a star rating it has a tombstone rating instead. Anyway, i launched the drone having done another chuffin low light level re calibration and flew straight up, well looking on the monitor i couldn't see much, it was a combination of being dark, my poor eyesight and i hadn't turned the brightness up on my monitor. I was flying by the map pretty much. Great fun.
It is a time exposure, not a really long one granted but at least a couple of seconds. Check the light trails from cars on the bridge. A little bit of LSL can be viewed plus the avoiding line at the top of the shot.
With time exposures using drones it really takes quite a bit of patience and taking many shots. The slightest breeze will ruin a picture even with a fully functioning gimbal. To increase the challenge level for this picture it is comprised of two frames stitched together. All this done and i still didn't get a chuffin train running through the station.
I found two versions. The colors of the printed numbers are different.
I propose to use:
Type 1: number 1 in red
Type 2: number 1 in yellow.
The northern calibration pond outflow in Milngavie Reservoir taken from the southern shore. This is the inlet to the reservoir & the end of the pipeline from Loch Katrine some 35 miles away and is one of the main water supplies to Glasgow. One of the largest public works undertaken in the Victorian age to supply fresh water and alleviate the continual pandemics of cholera & other water borne diseases in the burgeoning city. The adjacent Craigmaddie reservoir was constructed just a few years later and is even bigger when it was found this reservoir was not big enough! Between them they hold about 3 days water supply for the city.

First thing that came to my mind when reading the new theme of MM were the weightstones of an old Roberval balance, that belonged to my late grandmother (where it gathered dust in the attic) and now to my Mum.
We have no idea, how old this scale is, but it goes "back in the days" (at least in industrialized countries) ...
Good thing I was going to visit my Mum over Easter!
So here you see some of the weightstones, stored in a wooden box: two 100g weights, a 50g, 20 g and 10 g stone.
Diameter of the 100g stones: 3 cm (1.18 inches) - of the 10g stone: 1,3 cm (0,51 inches) - of the 20g stone: 2 cm (0.79 inches) - of the 50g stone: 2,5 cm (0.98 inches)
*********************
Das erste was mir bei dem neuen Thema für MM "Damals" einfiel, waren die Gewichtssteine für die alte Tafelwaage / Krämerwaage, die meiner verstorbenen Großmutter gehörte und dort im Speicher vor sich hinstaubte. Wir wissen nicht wirklich, wie alt die Waage ist ...
Was für ein Glück, dass ich just über Ostern sowieso meine Mutter besuchen wollte (wo die Waage jetzt als Schmuckstück steht)!!
So seht Ihr hier also einige der Gewichtssteine für die Balkenwaage in ihrem Holzkasten:
Zwei 100 g Gewichtssteine, und je 50 g, 20g und 10g.

Happy Macro Monday everybody!
Those with a drone in their photography arsenal know about the 'compass calibration' that's often times required before flying. Some extra time to set up for a shot is required with a drone vs a standard DSLR camera. The compass calibration nearly hung me on this one with the first attempt failing. Being down to the wire when the second compass calibration was successful, there were only seconds remaining to fly over and position the drone for this single shot.
Slicing thru the recently harvested fields within the Minnesota River valley, a westbound ballast train is nearing New Ulm MN on CP's Tracy Sub. Some Herzog personnel were on hand to assist in dumping, which would be around the Sleepy Eye area after sunset.

Purely for wildlife photographic calibration purposes! :-)
This year (again) I had precisely zero images shortlisted for the British Wildlife Photography Awards. Congratulations to those more successful than I.
Having a nightmare calibrating my screen (first time i've tried). Wondering how this looks to others? I won't say how it looks to me so I don't influence comments but if you wouldn't mind commenting on how it looks on your screen I'd be really appreciative.
Thanks in advance!

Always curious, always adventurous, always questioning, quizzical, timeless. And ageless.
Weird with the screen calibration/settings. When I exported the image from LR everything was the way I wanted it, still enough detail in the shadow parts, but when I saw it here after uploading it ... details gone. Too dark. Everything. Yikes. I hope that it looks better on your monitors than on mine.

A Happy Macro Monday, Everyone!
Thank you for your comments and faves, they are always highly appreciated!

Hello from the other side....
I tried to get tickets for Adele's show in Amsterdam next June but I could not get through.... pity! I will try again on Monday as there will be extra shows.
However, that's not what the pic is about.
I had been complaining for a while about the Sigma 50 1.4 ART. The focusing was off. I like how I can bitch about things and then Big Human will do some magic google trick and he can fix it. He found out how to calibrate the lens and it was off indeed. He needed test shots to see whether the calibration had helped. I think he could have used Karel for it but instead he insisted on taking my picture. It was inconvenient as I was washing my hair.
So, hello, from the other side... of the lens :)

BFS calibration aircraft parked in Riem’s Westpilz parking area.
BFS operated seven HS-748 (D-AFSD, D-AFSE, D-AFSF, D-AFSG, D-AFSH, D-AFSI, D-AFSJ). D-AFSH was delivered to BFS in December 1975 and flew on for them until 1995. It went on to West Air Sweden as SE-LEK in February 1996 and to Air Creebec Cargo as C-FPJR in May 2007. (Sources: jabog32.de, planelogger.com)
Active at least until September 2019, possibly even today (March 2021).

Messier 31 with Zenithstar 61ii and DSLR No Calibration Frames
This was one of those rare, beautiful nights when I wanted to just admire the heavens ... to do something less stressful ... something more simple ... with a very small telescope and a cheap DSLR. This William Optics Zenithstar 61ii was mounted on an iOptron CEM25P with guiding using a very small ZWO 30mm fl 120mm guidescope and PHD2 guiding software. No darks or other calibration frames were taken. Just the 10 exposures at 240 seconds each. ISO was set to 800. The site was a Bortle 4 and the temperature was 15 C (59 F). The Canon T7i DSLR sensor temperature was 21 C (70 F). I was curious how low the outside temperature had to be to use an uncooled, stock DSLR without worrying about background noise. I'm pleased with the results.
Capturing the exposures was done with APT. Processing was done with Pixinsight. Polar Alignment for the evening used SharpCap Pro. If you look closely at the NGC 206 star cluster contained in the Andromeda galaxy, you can see individual blue giant stars ... individual stars in another galaxy ... with a 61mm telescope. The technology available today is amazing.
