When I export to a jpeg file format, and choose 100 (%?) on the quality slider, the resulting file metadata has a resolution of 300 dpi,and say a file size of 4.54mb. If I drop the slider down to 50, then the resulting file resolution is still 300ppi, but the file size is 140kb. I am guessing that this is simply playing with compression? The image quality doesn't seem too bad. Note that I cannot see resolution in the metadata when viewing in Bridge - had to use a third party program online.
Like others I wish to post images to web pages at 72ppi, which helps a) bring down file size, and b) discourage people from downloading and printing for wall prints etc.
Is the 50% version doing this, or is it still a reasonably high quality to print. As others have stated in other posts I am not interested in exporting as a Tiff - no good to post to web.
