lsupremo you sound as tho you have Adobe stock and are fearing a crash; will Adobe be smart enough to consider Affinity as a threat, Perhaps.... or will it Laugh like GM when the first small cars [VW] arrived at the USA Ports ? ! Such a comparison as you asked it truly a Masters Thesis level project. Many confuse LtRoom with photo edit programs... the focus is different as would be the difference in LtRoom and Affinity.
The difference discussed by an expert:

Ten reasons why if you have LtRoom you need Photoshop [or Affinity.]

Obviously, as stated, I do not have experience in Affinity, or Lightroom and do most of my work in PSPro with Topaz suite. More the art type of photo enhancement person... painted years ago... never as good as Baby Bush is, tho I would have made a better President! Certain no war to assure a second term that has lasted 16 years!!


There is a world of comparisons if you Google just what you asked, "Compare Affinity and Lightroom".. Affinity for Mac has been there quite a while but with the intro of [5 years in development Windows Affinity] both have been written with new code from scratch. No, Scratch is not a computer code... scratch = like new. There has been a recent free update which has added a lot... including Macros for automation. [PS calls them actions others call them scripts]

One big comparison is that Affinity can be purchased for $50 vs the ransomware loaned to you monthly for a fee by Adobe. $120+ per year.

I will add, Affinity has a paint program "Affinity Designer" $50 program which fits in the Affinity family and has a $40 thick hard cover "workbook"! Also Affinity has just added Affinity for iPads which will addict the young iPhone/pad photographers. Young will not spend $ for Adobe... and will say "My Grandpa use Adobe Stuff, old fashion stuff." Nor will many spend big $ for DSLR when all they want fits in their back pocket.
