Ipad must have a retina display.
And on which device are you viewing both the files ?
Whatever platform I view the jpg's on the iPAD images look much sharper and clearer. And the iPAD jpg's are only 72 Dpi!
This is nothing to do with the platform viewed on.
What exactly do you mean by ipad jpg here ?
View both the images and on same device and check the difference.
Please share a screen capture.
The DPI is a totally meaningless number here. Do not assign meaning to this number.
Ppi - pixels per inch - is metadata which is only used for printing. It has no effect whatsoever when viewing an image on screen.
OK Thanks for pointing that out Per I had forgotten...many years since I bothered reading up on the Dpi settings!
But the fact still remains that when I export my FULLres Photoshop images (PSD) to 1296 Pixel Width JPG's with LightRoom they do not look as crisp and sharp as an iPAD jpg image of the same(1296w) pixel dimensions.
It is not clear whether you are viewing the the exact same image on the ipad as on your computer.
I suspect not, since you are talking about 1280 and 1296 pixels.
To make a valid comparison, you must use the same image.
