There are two different sets here.
First up is the 5 Day Deal
The general premise is it is a bundle of marked down software, tutorials, classes, etc, that's for sale for 5 days before the subject/bundle swaps to something else. It's sponsored by Wescott, Adobe, SmugMug, and a bunch of other companies. Supposedly $2400 in stuff for $89 with the proceeds all going to charity. So different kind of Humble Bundle of sorts I guess.
Plus you get a copy of Luminar 2018 (retails for $60 and is an alternative to lightroom) so if you're looking for an editing program, you're basically geting everything else for a couple bucks extra.
Number two is Corel Photo Mirage marked down to $60 from $70.
Not a huge savings, but it's a pretty interesting program. Basically it lets you turn a single photo into a cinemagraph. I've been playing around with the trial for aurora photos and the results are pretty neat. If you get carried away it looks like crap, but being subtle can really make things interesting. I haven't bought the program, so I can't upload anything though. But it's pretty simple to use, like the video shows.
