ty! i'm glad you enjoy the tool. As for whether or not this tool could replace a professional colorist, I think it depends on the specific project. For some projects, Palette could do a great job of automatically colorizing photos, and for others, a professional colorist would still be necessary to get the best results. Especially when the projects require historical accuracy or a high aesthetic standard. it also mak…

Even if the results are not 100% historically perfect, 99% of the hard job is done. Skin tones, plants, skies, water... they all look incredibly good, and the object segmentation is almost perfect too. The tool seems to struggle with fabrics, but that part is by far the easiest to fix with a traditional photo editor. Congrats man. You made my mom happy this evening. Please keep a free tier on your tool.

its fast and looks absolutely stunning but if you've done enough hand work you can still spot flaws (that are easy to correct by hand). The easiest to see is probably the use of black in parts of the face that are not dark shadows. Its slightly under-colored, it had to draw the line some place. It looks like black smudge's left and right of the nose. Then again, few/no one would notice without looking for it.

edit: if a human made these this comment would not exist. It makes A fun angle of AI, it can take criticism and do useful things with it. Many humans fail that challange.

Wow! I am impressed. I uploaded a WWII photo of airmen posing in front of their plane and got an amazing result. I’m not certain if WWII era life vests were bright yellow, that seems out of place, but it’s a good guess if not.

Found some that are yellow, not sure how bright we're talking - https://www.ima-usa.com/products/original-u-s-wwii-usaaf-mae...

Jaw dropping, that's the approximate shade it used in the picture.

Here is the B&W photo I tested with (I think "base" or "ambient historic" palettes are best):

It also did really well with the different skin tones of the Tuskegee Airmen:

It did not do so well with this grainy photo of soldiers w/ a captured German flag:

If you use the "vintage charm" filter it does a good job with the flag raising at Iwo Jima:

Today I was thinking of some sort of NN trained for colorizing photos, and then I get here and there's an AI right there...

This tool works really well. The text prompt helps, too. The suggested colors leak to surrounding objects (I forced a red skirt on a traditional costume I knew was probably red), but it looks really good.

Did you decolorize pictures originally in color in order to train the model?

I gave it ansel adams photos which it did really well on. Then I tried some famous national geographic photos, like the these: https://www.nationalgeographic.com/photography/article/meet-...

still impressed

I decided to go really old, so I tried "Valley of the Shadow of Death" from the 1850s where we get some red and blue cannonballs, but that's fine.

(Genuine) question, and no snark intended: why do so many people want to change history? Black and white photos are - for many of us - part of our shared historical record. Is there really a need to improve (=change) them? Can't we appreciate them exactly as they are, without modifications?

To me at least, it's just entertainment. Do you find it offensive to the past?
