Someone pointed out to me that ChatGPT can create a Film Simulation Recipe that replicates the look of any photo that you upload. Just share a picture with AI, and it will analyze the look and produce a Recipe that matches. But can it really do that? And, if so, is it accurate?
So I gave it a try. I uploaded a picture and asked AI to replicate the aesthetic of it with a Fujifilm Recipe. Sure enough, it produced one. I also asked ChatGPT to tell me which Fuji X Weekly Recipes are the closest. Let’s examine the results.
Test 1


The top picture is the camera-made JPEG captured on my Fujifilm GFX100S II using the Nostalgic Film Recipe (a Film Dial Recipe). I uploaded it to ChatGPT and asked it to make a Recipe based on that image. The second picture was reprocessed in-camera using the settings that AI provided. Quite obviously, they are pretty far apart and are not a good match.
Some of the settings are the same. Both pictures use DR400. Both are Grain Weak (although ChatGPT chose Grain size Large). Both have Color Chrome Effect Strong and Color Chrome FX Blue Weak. Noise Reduction is -4 on both. The White Balance Shift is +2 Red & -4 Blue. All of the other settings were different—for example, the Nostalgic Film Recipe calls for the Nostalgic Neg. film simulation, while AI chose Classic Chrome. The Recipe made by AI isn’t too dissimilar to Kodachrome II, although not an exact match. I asked ChatGPT to tell me which Fuji X Weekly Recipes were the closest, and it suggested Kodak Ektar 100 and Kodak Gold 200.
Test 2


The top picture is the camera-made JPEG captured on my Fujifilm GFX100S II using the Fujicolor PRO 160C Warm Recipe (which is also a Film Dial Recipe). The bottom picture was reprocessed in-camera using the settings that ChatGPT provided. They are far apart, and are not an especially good match, although it is slightly better than the first test.
The Fujicolor PRO 160C Warm Recipe uses the Reala Ace film simulation, while ChatGPT chose Eterna. Most of the settings are divergent. I don’t have a Recipe that’s especially close to the one made by ChatGPT, but Timeless Negative is probably the most similar. The Fuji X Weekly Recipes that AI suggested are the closest are CineStill 800T, Kodak Ektachrome 100SW, and Kodak Vision3 250D.
Test 3


The top picture is the bottom image from Test 1. I asked ChatGPT to make a Recipe that matches it, to see if it would suggest the same settings that I used to make it (which is the Recipe AI had made just a few minutes earlier). The Recipe that it came up with was not the same, and also not a great match. Instead of Classic Chrome, it wen’t with Classic Negative. While only somewhat similar, Fujicolor Blue is probably my closest Recipe. The Fuji X Weekly Recipes that AI thought were the closest are Kodak Portra 400 and Kodak Portra 160.
Test 4

I re-uploaded the first photo from Test 1, and asked the same question to see if it would suggest the same settings, or if it would change them. Unsurprisingly, it was completely different, this time choosing Astia for the film simulation (I didn’t bother to reprocess). It suggested that my Kodak Portra 400 Recipe would be the closest match.
Conclusion
I’ve said before that ChatGPT is a neat little card trick, but once you know how it works, it isn’t nearly as impressive. I’ve also said that it will only get better with time. Both of those statements still seem to be true. While AI can analyze a picture and produce some Fujifilm settings to try—which is amazing—it isn’t very accurate. It can also suggest Fuji X Weekly Recipes that might be similar, and it is a little better at that, but still not especially good.
I have zero doubts that with enough time—and it may only be a couple of years—ChatGPT will be able to analyze a photo and produce a Fujifilm Recipe that is pretty similar. It might be even closer to suggesting an existing Recipe that isn’t far off. It’s not there yet, though.
I’m certain that ChatGPT was trained on my website. When asked directly, it says that it wasn’t, but states that it was trained on various photography blogs and forums. When I asked it to name some specific ones, the very first it listed was Fuji X Weekly. So, yeah, AI did some of its learning from my website, which of course I did not consent to nor was I compensated for. I believe that this training is ongoing, and it probably will even learn from this article that you are reading right now. This is wrong, and eventually the courts will likely determine that it is completely illegal; however, by then, the damage is done, and there’s nothing that can be done.
With all of that said, I had a conversation with a friend of mine who is super intelligent (he’s a scientist) about AI and ChatGPT. He said that he is not concerned about being replaced by AI, but he is concerned about being replaced by someone who knows how to use it better than he does. I don’t think it is prudent to ignore ChatGPT completely. While undoubtably ethically sketchy, it is a tool that can sometimes be used effectively, if you understand its strengths and weaknesses. I’m not sure what that means for me specifically, other than it is good to test it now and again to see how far it has or hasn’t come. It definitely has made some progress since the last time I tested, but not a lot.
