Hi all,

Whatever setting I choose on my digital camera, for draft quality or high quality, when I use the FILE, IMPORT, function in Photoshop CS the photos are all the same size and only 72dpi. Anyone know if this is a camera problem or a setting I need to change in Photoshop?

Thank you
Stephanie
 
Are you sure they are the same size. Have you checked the file size at the bottom left corner of the p/shop document. If you go to the 'Image Size' diallogue box and check 'document size' you will probably see that the measurements are huge at 72dpi. Uncheck the "Resample Image' box and change the resolution to, say 300dpi. You will see that the image measurements will reduce dramatically.
 
Hi Stephanie

I would have thought all digital cameras would export their pics at 72 dpi? It is only the number of pixels in the image that will vary. 72 dpi means nothing - until output

For example if i have a lovely digital on my computer - and it is 18mb uncompressed - what resolution is it? Who cares... it is the number of pixels that matters - and this alone that will govern what size you can output it

A picture that has 3,000 pixels in one axis would arguably be used at approximately 10 inches maximum size - which would have the effect of reproducing the image at 3000 dpi / 10 inches = 300 dpi

Hope i am not teaching you to suck eggs!


Kind Regards

Cameras typically are not exporting at any ppi. The 72 ppi measurement is automatically assumed by Photoshop when an image is loaded without physical dimension meta information. Once you get the file into an image editing program, you may assign ppi.

Expanding on jimoblak & my comments about dpi - if pictures never went to print there would be no need for resolution at all. Monitors would simply render them pixel-for-pixel (unless there was a bounding box that restricted the size)


Kind Regards
