Hi all, I keep seeing on photos ...."this is a 100% crop...". To my old brain a 50% crop would mean you have cropped out half your photo therefore 100% crop must mean you have no photo left... I know this is not the case so could someone please enlighten me. :?:

It is a crop that shows a small portion of your pic at 1:1, 100% actual size.

When I open a photo in photoshop straight from the camera .. if you look a the tab for the image... mine open at 25%. So if you zoom in until it says 100%...and crop it there .. that is a 100% crop. :)

While we're on the subject of cropping. I sent via email to Walgreens a photo to be printed. I ask for an 8x10 size print. The photo is of myself and 8 others but I left enough background on each side and top and bottom. When I got the print, the person on each side of the photo were cut in half. There was no background left on either side. I ask why the people and side background were cut off and the lady told me that when they scretched the photo to make it 8x10 size it crops it and therefore cuts some of the photo off. I told her it should not crop any of the photo. It should be just as I took the photo. Even the people in the photo were closer up as cropping would bring in closer. She ask me to step back with her and look at the machine that makes the prints and she said she could fix the problem with not cutting off any of the photo on the sides but it would cut some of the top and bottom putting a white trim on the top and bottom of the print. So now I have a print that will not fit an 8 x 10 frame without showing the white trim unless I cut the white part off and then it will not be a true fit in my frame unless I have a frame made specifically for this print. Can anyone explain or advise as why this happens or should it be happening.

It has to do with aspect ratio - think of televisions, the old ones were relatively square (a 4:3 aspect ratio) so to display a cinemascope (or Panavision or...) movie (roughly 2.35:1 ratio) on them the film companies would crop the image. What they cropped depended on where the focal point of the scene was, often center but sometimes left or right. Some folks hated that so they started releasing home movies in "letterbox" format with a blank band at the top and bottom of the screen so you would see the entire frame of the movie. New "High Def" televisions are 16:9 aspect ratio which approaches a cinemascope movie but not quite... :(

Your photo was perhaps formatted for 4x6 print size (3:2 ratio) but an 8x10 print is 5:4 ratio so the clerk helped you out by "letter boxing" the photo with a border

your camera makes an 8x12 rather than 8x10 shape. It's all about the original SHAPE or PROPORTION of the image. If you want to make 8x10's just remember to leave some more space on the edges. This has always been a problem. It's rare that a camera format is exactly the same as print formats. Your camera is more like a 4x6 or 8x12 proportionally.
Another problem is that computer paper is generally 8 1/2 x 11 rather than 8 x 10. You'll have to crop the image and cut the paper to fit an 8x10 mat or frame. They do make regular 8x10 paper for computer printers, but you'd still have to crop off some image to fit it.
A lot of pros used to shoot Hasselblad which was a square negative. You had to either crop top/bottom or sides to fit almost any normal rectangular print size.

I have a T2i camera. I had a 16 x20 print done and none of it was cut off. This is a big problem at the lab with cutting off parts of photos. And, I do leave room on all edges when I take the shot.

It's aspect ratio as stated before. Somewhere on the forum I have a samples of a print posted that is cropped for different print sizes, it shows what will be lost.

Print sizes and ratios are very important to learn if you are thinking about going pro, nothing worse that ordering a print for a client and cutting Grandma in half. :)

So, explain ratios and print sizes. How to get it all correct.

I'm currently away from my desktop so I don't have access to my file folder that has my samples but a great link that will get you started and has samples of print sizes is:

Your request would require quite a lengthy post. See if this article helps.
