iPad storage capacity for photo storage

My 64G wifi iPad has a capacity of 59.2 gig available to me (for apps, music, photos etc) after the iOS is taken into account. Only you know how many photos fit on your 8 gig cards (as it depends on factors such as what you shoot, whether you use raw ad/od jpeg, and the ISO that you use) - multiply that by about 7 and that's approx how many would fit on the 64 gig iPad.

Do you save your photos in raw format or JPEG? That will make a big difference. I use raw on a 12 mpx camera and each photo is between 12 and 14 Mb, but that's with in-camera lossless compression.

By my tests of iPad1 I do not believe the iPad can show the full resolution of photographs beyond about 2 or 3 megapixel because there is not enough video memory. If you open an 18 megapixel picture you will not be able to zoom by your fingers to see the 100% crop version of your pictures. Zooming in will cause them to pixellate, unlike zooming in on your desktop or laptop. Thus, you may want to create a reduced resolution collection of versions of your photos for iPad and store those on your device, unless you think you will be emailing them to folks from the iPad. This will allow you to put many more pictures on your iPad because you will not be using memory space that you can not see by zooming, anyway.
