I have always been a fan of free software. I recently have come across two excellent sites for free or almost free software. The first site is Shareware On Sale This site offers a new piece of free software almost everyday. A good many of the titles are of interest to photographers. I have downloaded resizers, pdf editors, image editors, and other interesting software. Usually, you have to download and complete the installation in the 24 hrs that the software is available. You get a valid license. Most does not come with support or upgrades. You can pay a little more to get that if you want. All that is required is that you create an account.
The second site is Bits du Jour.
Again, there are many free giveaways, almost everyday. This site seems
to have a broader range of titles of interest to a bigger audience.
However, there are still many titles available of interest to the
photographer. All that is required is that you create an account and
like Bits du Jour and the software maker on Facebook. You can always
change that later.
I frequently get useful software from both of these sites without issues.
