Callforentry.org is specific about submissions
When sizing your photos of your art work for submissions:
They require name of painting, dimensions, medium, price and a description.
Hint: For photographs and paintings – the depth will always be 0, not spaces.
These are their sizing requirements:
What are the image specifications?
All images must be formatted to the following specifications in order to upload them successfully into the system.
- Dimensions: 1920 pixels on the longest side
- File Format: Save all images as BASELINE Standard JPEG. Do not save as a Progressive JPEG.
- File Size: JPEGs must be under 1.8 MB.
- Color space: Save images in an RGB color space, preferably sRGB.
This means that you need to take your photograph into a photo software program and make sure the longest side is 1920 pixels exactly. When saving in Photoshop, save for web. Make sure progressive is not clicked and the photo is optimized.
