How do I know how big my jpeg will be when I am using RAW files ? I am trying to upload photos to a stock house that only accepts 4 meg files in jpeg or TIFF format
Images vary. Just do it and check the file sizes.
Images and camera outputs vary so experiment with the two different file types and your images, but my guess is that highest resolution 4 MB jpegs will deliver better print images than 4 MB TIFF files.
