So I have been trying out various IPAD photo editing software. This is B and W conversion with Adobe IPAD product.
Photogene - not bad, but can only export out a 4mg file, the controls sliders can be difficult to get the precise amount of correction you want. Can handle RAW files, only $5.99
Photoshop for IPAD - love the controls and the precision of adjustment, slow as can be. But it is FREE except for the $4.99 you pay for add on noise reduction. I like the interface more with ADOBE product.
The best cheap software - photo sync, allow you to transfer JPEG and Tiff files between computers, iphone, and IPAD via wifi. Fast and easy interface.
I am amazed on what they can produce for under $5.00.
