Preparing and Editing Your Image

If you follow these simple image file help guidelines, you should get great results from your Art Warehouse prints.

Resolution, File Size & Color

Image resolution should be at least 150 dpi. Please convert all colors to sRGB or Adobe1998 color space to avoid any color shift that can occur during the production process. We will print your file in either color space in which you submit to us. As for all you photographers using the newest ProPhoto color space, current technology does not support printing that color space. So convert to Adobe1998 and then submit your file. Most current digital cameras can produce a big enough file for enlargement to even the biggest sizes listed. We accept file sizes up to 25mb on our site. If you require upload of larger size file, please share a folder with us via an online file share such as WeTransfer or Dropbox.

Editing Your Photo

We work in a color corrected environment. Your image will appear brighter on your monitor than what will actually print out. To get a closer idea of what your print will look like, and before you edit your file, reduce the brightness of your monitor down about 30%, then edit your file. This will be a closer representation of what your print will look like when printed. We do prepare each image before it is printed and based on what media type is selected. This will ensure that it will look its best when printed.

File Types Accepted

We accept the following file types: JPG or TIF.

Image Crop - Aspect Ratio

Most of the current digital cameras have sensors that are not equal to the framing industry sizes. To avoid having the image arbitrarily clipped by our photo printing service, you should crop the photo to the correct aspect ratio, prior to selecting the print size. Aspect ratio is the relationship of an image's width to height, or its proportions. Digital cameras produce files with an aspect ratio of 4:3. But many common photo print sizes have a different aspect ratio. For example, a 4 by 6 print has an aspect ratio of 3:2; an 8 by 10 has an aspect ratio of 5:4. Understanding aspect ratios can introduce confusion, but it can really be explained quite easy. We all had to do basic fractions in middle school. If you can remember how to factor fractions, then you can figure out aspect ratios. Basically you can use fractions and look at your photo size as a fraction. Width and height become x/y. Factor your width and height to the lowest common denominator and you will have your aspect ratio. Then to calculate a new size, multiply or divide the numerator and the denominator equally. For example, if you have a photo that is standard-out-of-the-camera without any cropping made to it, it has a ratio of 4:3, or in framing/printing world jargon, an 8x12. Now determine what size you want printed and find the ratio which will match the original aspect ratio, or crop the image to match the aspect ratio you are wanting in the print. Some examples of relationship of sizes (or ratios) are: 8x10 = 16x20, 24x30, 32x40 - This is 4:5 ratio 8x12 = 12x18, 20x30, 24x36 - This is 3:4 ratio There are numerous calculators out on the web to help determine aspect ratio (if you are like us and can't do math in our heads...).
