My impressions of Photoshop Express for iPad...
Since my original post, I've since downloaded the free Photoshop Express and bought the $3.99 camera add-on, and I really like it. I just want to say that I went in knowing that this was NOT a full-blown Photoshop for iPad.
My main purpose for getting something for the iPad like this was so that I could easily move JPG images from my Nikon to the iPad, make simple tweaks, and immediately upload to the web while in the field. It turns out that Photoshop Express is fantastic for just this!
I've posted a quick review of it on my website:
SierraPhoto.
I typically shoot in RAW, but it's only a second to change to JPEG for a quick upload once I get the RAW shots done. My workflow between Nikon, PS Express, and upload is very fast at this point. PS Express is a great little app!
