What is the advantage of buying Corel Paint shop Pro 2018?
I use both because they augment each others tool set. The features in PSP that don't exist in PP are too numerous to list but depending on tour work you only need PP.
In photo-paint the auto adjust is pretty good would you say the same is for Paintshop Pro?
I think the auto adjust is better but I rarely use them in either program. I don't know where you are in the world so I can't judge what you'd pay but what I can say is that except for postscript capabilities, PSP is a very capable choice, a much smarter choice than Photoshop. In the U.S. a new license is $80. I bought it a few years ago and kicked myself in the head for not getting it sooner.
I'm not someone who does this as a hobby, I do thousands of architectural images, the past issue of Environments for Aging had 24 of my image edits for award winning projects. I am the image editor of choice for several architectural firms. For over 20 years Photo-PAINT has been my editor of choice and still is, the last 3 or 4 years I've been augmenting with PaintShop Pro and I just upgraded to version 2018. What does that say?
It's a comprehensive program it will take a few months to get used to but well worth it.
Download a free trial and decide yourself. Basically, PhotoPaint is the internal image editor of CorelDRAW, while PaintShop Pro is the standalone professiona image editing software. www.paintshoppro.com/.../
I didn't recommend the trial because the application is so comprehensive 30 days is not enough time to learn it unless you work allot at it and the U.S. cost is so low.
