[QUOTE="Geoffc, post: 177815, member: 8705"] Dave, it's interesting that you assume I'm wrong because my facts (See attached images) contradict your understanding. The size of a file in bytes is determined by pixels Wide X Pixels high and that is a fact barring a few meta tags. Explain how you have two files with the same pixel lengths that are different sizes? Perhaps Lightroom doesn't export properly on my PC or basic physics is not behaving as it should!! I don't want to fall out over this, but I will need to see your files to understand what you're saying. If you're exporting from Photoshop where you specify image size etc etc then you may think you're getting the situation you describe but it will be changing the width and height in pixels as you mess with ppi. The images below are 1ppi and 200ppi, both are 1000 pixels wide. [ATTACH=CONFIG]45434._xfImport[/ATTACH][ATTACH=CONFIG]45435._xfImport[/ATTACH] [/QUOTE]
