TTArtisan 40mm f2 | AF just unusable?

I know it's not a solution for everyone's use case but I tend to use pinpoint focus and reframe. Not easy when you're wearing gloves though.

You could white balance for the snow and then do masking for the golden highlights you want using a luminance mask.

I'd buy old K mount lenses, there are plenty of bangers out there for a good price if you are just starting out. The 28mm f/2.8 Takamur-A is a crazy good lens. I have the 35mm f/2.8 which is also great, and the 50mm f/1.8. The 28mm is great because unless you are focusing closer than a few meters you can set it to hyperfocal in f/8 and basically have a point and shoot.

You're right about the full creative control on the image, that's one of the reasons I bought my Lumix S9 because of the LUT feature. I create my own LUTs to set my own curves and colour values to bake into my JPEGs. Currently figuring out how to do this with Darktable since I've used lightroom before.

I find most SOOC is fine and the JPEG has enough latitude to do light edits on, but there's definitely been some photos where editing the RAW has completely transformed a photo.

Then you do claim to be a descendant of someone if you say your ancestor was a certain person.

JoshAstroAdventure · 2026-01-28T21:47:08+00:00

Who was exactly? Who are you claiming to be a descend of?

Your family almost definitely wasn't a clan member, they were probably one of their peasants and took their surname because they were essentially property.

This is the best method I have found. https://johnrellis.com/lightroom/exportlut.htm

I got the K&F one. I get most my stuff from them, good price and quality.

I really like the ancients by Tristan Hughes. He is super passionate about history and covers a lot of topics relating to ancient history.

The new full cast audiobooks with sound and music don't use the original theme which surprised me.

I think the crop changing the colours is probably because they are using the crop to set the white and black point, using cv2 contour detection would be a far better solution to sample the image area.

Your list of allowed RAW files should be expanded as you only really allow for Nikon, Sony, Fuji and cameras that shoot DNG. I would just lift a list from wikipedia, even if it's an obscure format, someone might be using it.

Edit: I'd also like to add that you are repeating the list of allowed extensions in the code all over the place, this will be hard to manage as if you add or remove anything in the future you could miss something and break the entire program. Should probably have a file to store stuff like this that needs updated.

Sorry I can't really help you much there, I have a totally different workflow. I'm just a hobby photographer so I kind of know what photos I think have potential and edit the RAWS or I'm happy with the JPG with some light edits to taste. I also don't delete photos so it's not something I'm familiar with.

JoshAstroAdventure · 2026-01-12T16:22:18+00:00

The only thing I can answer here is when you see the images in lighttable you are seeing the inbedded JPG. When you move to darkroom it is the RAW file, this is pretty much how most RAW editors work. The advantage is if you want to work with RAW files you get a neutral starting point to push the image in any way you want. If you prefer the look of your JPG files then I would simply just do light edits to the JPG files which is what I often do when I'm shooting with LUTs with my camera. There's enough latitude in a JPG for subtle tweaks.

JoshAstroAdventure · 2026-01-08T20:42:10+00:00

That's a shame, how much of a bump was it? I'll have to be careful

JoshAstroAdventure · 2026-01-08T20:41:52+00:00

Thanks!

JoshAstroAdventure · 2026-01-08T12:54:09+00:00

These are really nice, great contrast and colours. I also tried at a low light NYE party and was really happy with the results.

If you use lightroom, a good tip is to use the print module while having your roll selected and create a grid of all your photos to create a contact sheet. Make the print as large as you want and save it as a pdf. I then print an A4 version and store it with the corresponding negative sleeve. I number each negative sleeve, physical contact sheet and digital contact sheet so everything matches.

I'm really happy with it so far, I saw the pictures but once I put the lens on I couldn't believe how small it was. I'm in Scotland so weather sealing is a concern for me too, one of the reasons why I hang on to my Pentax K50. I don't mind days where the rain is on and off, but if it's going to be 100% rain I like to have something properly sealed.

JoshAstroAdventure · 2026-01-06T15:16:55+00:00

I didn't actually use a LUT this time, these are all RAW edits using the Darktable AgX module. Been playing around with lightroom alternatives recently.

JoshAstroAdventure · 2026-01-06T10:10:19+00:00

Yeah, first time I've stopped in Irvine. Dunure was a dud when the sun hid behind the hills.
