Crop?
CROPPING Those odd red lines on your photo. Your photo likely won't fit all print sizes without surgery. But at least you're empowered with your own knife. Click the red "adjust" button to choose your crop. Gotcha: If you do nothing, only what's inside those red lines will print on your photo. Option: Choose the no-crop option from the pull-down menu. Instead of cutting some of your image to make it fit the paper, it will add two white borders so nothing is lost. You can read more at SmugMug's Help section dealing with cropping found here
There are other reasons to crop! With many print sizes available, you might want to focus in on a certain segment of the image. In the photo here, I've highlighted a square format on a rectangular picture.
The "crop box" that will let you choose which area you want in the picture is a red outlined box that matches the size of the print you want (see above for an example).
The print you receive will match the area contained within the red "crop box" or, in the example to right, the see-through red square.
Please make sure you crop your photos to capture the good stuff or the stuff you think is good!
