If you've ever created a photo that you went to crop to 8x10 but then realized that you didn't give yourself enough room to crop, then I have good news for you. I do this all the time, especially with studio portraits. I frame the portrait perfectly only to realize that I should have stepped back and given my photo some room to crop later.
The photo above was originally cropped to 7x10, and I just couldn't crop to an 8x10 without losing his hands or his hair.
Why would I want an 8x10? First, I typically deliver 8x10 prints to my clients. That's my standard print size. But I also need an 8x10 crop for vertical photos on Instagram. That's the narrowest vertical photo that Instagram will allow. 7x10, 4x6, 5x7, forget it. Instagram only allows a vertical 8x10 without losing some of the photo.
There is an easy solution for this problem in Photoshop. All you need to know is how to extend the "canvas" followed by a select-and-fill (or maybe a select-and-distort) and you're done.
Don't know what that means? Watch this video I created using the image feature here for full instructions.
