Being a novice of sort I am not sure if I understand what is happening when I increase the canvas size of my image. Here is what I am trying to do, tell me if my understanding is correct or not: I have a 4/3 Image (Olympus E-330)and I want to have a print made that will be 9"x12." The Lab say it does not do 9x12 only 11x14. So they told me to increase the canvas size to 11x14 which when printed(Full Frame) by them it will leave a white 2" border around the image. I can either leave that border or cut it off and have my 9"x12" image. How do I increase the canvas size to make sure that I get a 9x12 image?
If you have Photoshop go to Image>Canvas Size, then choose your dimensions to be inches and adjust as needed.
Thank you for the reply. However, was my assumption correct? Do I understand what increasing canvas size means.
Yes, increasing canvas size to 11X14 will create a border around your image, as the lab said. Make sure you select "white" in the color options.
Thank You for the confirmation.
It's more easily described as understanding proportion. If your image is a different proportion then the paper size it will be printed on, you'll either have to crop to make it fit, or add canvas to take up the space. The problem with sourcing printing, is that images need to be prepared at the size and proportion of the paper it will be printed on, or they will be cropped to "best" fit, which is always not the best way to do it.
Here's an article on my web site about proportion and adding canvas to match the paper size.
