Mark G Posted July 16, 2014 Share Posted July 16, 2014 Hi There, I'm new here on Alamy and trying to understand the difference in size of an Open JPeg and Disk Size. I Shoot with a Panasonic DMC-G1 I work directly from raw (rw2 on the Panasonic) which is around 14 MB Image Size. In Photoshop it is saved to - 12 - J Peg Max Quality. After editing and saving to JPeg the Image is around 8 MB on the disc. How do I determine the Open JPeg size so that I can be sure it meets Alamy Criteria? Thanks Mark G Link to comment Share on other sites More sharing options...
spacecadet Posted July 16, 2014 Share Posted July 16, 2014 Anything over about 8MP is big enough for Alamy, Your uncompressed size is three times the sensor size, so about 36MB. The compressed size is irrelevant because it depends on the amount of fine detail in the image. Link to comment Share on other sites More sharing options...
Jill Morgan Posted July 16, 2014 Share Posted July 16, 2014 Since you are using Photoshop it is very easy. At the bottom left hand part of your screen, you will see two number separated by a backslash. These represent current file size and unaltered file size. Looks like this: So this picture is 51.3 mb both ways as it hasn't been altered. If I adjust the size of the image the first number would change to the new file size based on my changes. So when making cropping changes or anything that would affect the size of your image, just check there after making the changes. If the first number is 24mb or higher, you are safe.

Mark G Posted July 17, 2014 Author Share Posted July 17, 2014 Thank You. It's easier than I thought with Photoshop. I can get test images posted now. Mark Link to comment Share on other sites More sharing options...
