For images of people generated from scratch, Nano Banana always adds a background blur, it can't seem to create more realistic or candid images such as those taken via a point and shoot or smartphone, has anyone solved this sort of issue? It seems to work alright if you give it an existing image to edit however. I saw some other threads online about it but I didn't see anyone come up with solutions.
Maybe try including “f/16” or “f/22” as those are likely to be in the training set for long depth of field photos.
I tried that but they don't seem to make much difference for whatever reason, you still can't get a crisp shot such as this [0] where the foreground and background details are all preserved (linked shot was taken with an iPhone which doesn't seem to do shallow depth of field unless you use their portrait mode).

Those are rarely in the captions for the image. They'd have to extract the EXIF for photos and include it in recaptioning. Which they should be doing, but I doubt they thought about it.
Photo sites like Flickr do extract EXIF data and show it next to the image, but who knows if the scraping picked them up.
Looks like specific f-stops don't actually make a difference for stable diffusion at least: https://old.reddit.com/r/StableDiffusion/comments/1adgcf3/co...
