Hi Damien
Something odd going on here with my brain or my computer or everything. lol.
If I use, say for example the crop ratio of 5x7, save as JPEG it is giving me just 370kbs (ok for web use Facebook etc but not for printing). If I were to print this at Photobox, it will pop up with a non-smiley face and tell me that the quality is not good enough for printing as it is too low a resolution. Now here is an even stranger thing going on. I managed to screenshot this image uploaded to here, but tried to do another screenshot showing the kbs size to save to JPEG, but it is now saving it to Dropbox. Flip's sake.. I have no idea what's going on as the first screenshot saved OK to my MAC hard drive.
You know that feeling when you have been working on files for a very long time, then suddenly something changes that is not quite right? That is my feeling last night. All other images before I went out to do moon pics, are 8-12mb and 30mb respectively (JPEG fine and RAW). So they are cropping and saving in the high quality size I would expect and need for printing different format sizes, whatever the pixel dimensions.
