For those of you planning to make prints as gifts, here is a better understanding of aspect ratios when preparing your files to send off to the lab, by the awesome Pamela Ann Berry from the photofocus crew.
“If you plan to print your photos, its essential to know that ratio to crop to. Otherwise you may end up with unexpected results.
What is aspect ratio?
Aspect Ratio of an image describes the proportional relationship between its width and its height. The most common aspect ratios are 4:3, 3:2 Other aspect ratios, such as 5:3, 5:4, and 1:1 (square format), are used in medium and large format cameras.
During one of my first professional photography jobs I was taught to always leave room for crop. When I first started taking pictures of families and groups it was natural to fill the frame. What I became to understand, cropping for standard crops and frames was essential to selling prints. If you fill a frame with a group shot and the image won’t fit into an 8 x 10 print, you lose the sale. I’m grateful for that experience. Learning to take pictures for the sale is now second nature to everything I shoot. Group shots are notorious for not fitting a standard very common 8 x 10 print.
Your group shot on a 3:2 camera will print without crops: 4 x 6, 8 x 12, 10 x 15, 12 x 18, 16 x 24, 20 x 30 & 24 x 36 However, most your clients will want an 8 x 10 verses an 8 x 12. This means when you take a picture, leave space open around your subjects.
Auto Crop Fail
My second major photography job was working at a print lab. A common problem labs see is auto crop fail. Often customers will upload a print, ask for an 8 x 10 and let the lab crop. Many of the online labs are now automated and will not look at a crop before printing.
Allow room and/ or crop beforehand to get the print you are expecting and one to make your clients happy. Your clients will also be grateful knowing they aren’t losing part of the print.
The Bottom Line
Understanding how your camera’s aspect ratio works and apply that to your shots. You understand your crops better then your clients. Your clients likely do not understand why an 8 x 10 won’t work with a picture you took. Keep your pictures print valuable and watch your sales grow and your clients come back.”
