Thanks, yes, the last two screenshots are enlarged portions of the image, once inside of LR with no artifacts, second one shows the artifacts after exporting. At 100% size, it looks exactly like it does in my screenshots. There was no resizing of the image done at all when exporting, still I seem to get compression artifacts when Im in fact not compressing anything while exporting to 16bit TIF without compression or resizing, am I? If I can see it on a print at normal viewing distance greatly depends on the size that I'm printing it, I'd rather just work with a flawless image without artifacts than having to hope for the best while spending lots of money on a high quality print.

Ok, but the scan wasn't the issue here? That looks fine! Its a color film, too. I suspected my digital noise reduction might be the source of the problem, but that doesnt explain why only the export is distorted, does it? It looks like a badly compressed jpeg to me, not like a 35 MB TIF/PNG file?

Hey there, today I took some TIF-files to my photolab of choice to get large scale prints of scanned and retouched film. Going over the pictures, the lab-guy noticed an odd blurry situation with the grain on one of them. He was certain it had to do something with a faulty scanner on my end, which I was sceptical about, back home I checked and the original file doesnt show any of said weirdness. I'm used to develop all my pictures inside of Adobe Bridge with Camera RAW, where you could not see the issue at all. I also tried to export the same picture from Lightroom, again it does only appear on the exported uncompressed 16-bit TIF as well as on a PNG I tried for troubleshooting. I'm fairly new to working with scans and prints as well, so I might miss something very obvious, but I was under the impression that TIF is a lossless format that should not compress or alter what I see inside of CRAW or LR at all unless specified? Thanks a lot! Full Image: Grain Pattern inside of LR (thats what it looks on the original scan data as well) Grain Pattern when exported to TIF or PNG

Wow, this is extremely helpful, thanks a lot everybody for taking the time, it is much appreciated!

Thank you, although the confusion remains ;) I'm looking for a correct diopter for my AE-1P, I'm quite certain that would be a "S" model - I do own one that gives +1, which helps compared to the naked alternative but isn't ideal. Can you hint in a direction of how to do a custom modification?

Just a couple years later I find myself in a very similar position, but even with this very helpful information I cant figure it out completely yet. My subscription is about +3 on both eyes, so pretty farsighted. To get a sharp view I figured I need a +3 diopter as well (which is pretty impossible to find) If the inbuild finder has a strength of -1, wouldn't I technically need a +4 to get to an +3 in total?! How come (-1) + (+3) turns out to be 4 and not 2? What am I missing?
