Just downloaded the latest, paid for, version of Infinity Photo, and I'm impressed. Having binned my PC in favour of a Mac (no regrets), this is the first editing program that ticks all the boxes (for me, at the present time).
I wanted a good raw processor, comparable to Photoshop CS4, and this comes pretty close. The program has plenty of bells and whistles for most needs, but, and most importantly, the main editing processes work really well. Infinity also operates in 16 bit mode for all functions through to the final image.
I was initially disappointed with the small size of the text (hard to read for an Old Git), but this was sorted in the Preferences.
Considering the extortionate price of Photoshop, at £40, this is a bargain, reminding me of Pixinsight, the best astro processing software money can buy, at a price that won't have you wincing in guilt and regret after the novelty has worn off!
