The images you upload to ShootProof can be up to 50MB each and no larger than 100 MP in size. (The megapixels an image has can be calculated by multiplying the width in pixels by the height in pixels of the file.) Your files should be at least 3000 pixels on the longest side. If your images are larger than 3000 pixels on the longest side, ShootProof will resize the image displayed in the gallery to optimize loading times, while (of course) preserving the quality.
The smaller your file size, the faster your images will upload, so you may choose to compress your files a bit. If you are using ShootProof to backup your photos, you may wish to upload the full resolution files.
We store your photos in the original size that you upload them, so if you download your photos back to your computer, or sell the original resolution digital download, they will always be the exact files you uploaded.
You should also ensure that the files you upload to ShootProof are JPEGs and that they are in the sRGB color space. (Uploading files in a different color profile may affect how your photos are displayed win the galleries with respect to color and vibrancy.)
