Fyi I’m in the alpha testing phase of software able to automatically crop and rotate scans with one click, no guides needed. It’s what I used in my post earlier in this thread its also how i did my entire psa sub in the return thread.
Soon ill be looking for people to beta test since it still needs a few more tweaks before a more general release
I asked this on the discord and the answer was they only scan above a certain service level apparently. Also, you won’t have scans of cards you bought from someone else.
Would that work with photos as well? The aligning and cropping is incredibly time consuming. I guess some edge detection software could do it, but I wouldn’t know where to start lol.
Most likely they are using a telephoto lens of some sort (70mm+ lens?) that is aligned squarely with the card and set up on a tripod. That gives you the flat/compressed look.
The light is probably a single source flash or continuous light with something to diffuse the light in the first one. Its looks to be placed head on at 60-80 degrees up from the card. Maybe even almost directly over head. They could also have another light on the ground pointed to the background to give the bright blown out look.
You can see the light set up in the second image reflecting on the marbles. Looks to be 2 lights (reflection makes it look like 4?) and they are a few degree each to the right/left of the camera. This provides a more evenly lit look compared to the first image. For this one the lights are angled 45-60 degree angle down to the cards.
Would look up product photography on YouTube. That would be a good start. Product photography isn’t my forte, but I don’t think I am too far off with my statements above.
JPEG is probably sufficient for ebay listings. They will probably be the smallest size if you plan on keeping copies of the scans forever. But they are lossy meaning the quality is slightly compromised. But if you’re not scanning for like archival purposes it probably doesn’t matter.
I think TIFF is primarily useful for applications in the printing industry and might be a bit overkill for ebay listings. PNG is probably the compromise between space and quality. It’s nonlossy so the quality stays high but the compression is better than TIFF
