depends on what kind of photo restoring and refinishing you need to do. PhotoPlus 9 is able to remove red eye, it has automated image correction and a scratch remover tool, correct over/under exposed images. You can see the new features of photoplus 9 here: http://www.serif.com/photoplus/photoplus9/ph9_newfeatures.asp
I like the replace color tool that you could use to...
Oh and by the way... i couldn't answer earlier because the forums didn't work :-(
Photoshop is the gold standard in the Photo Industry. I've compared the two and PhotoPlus has a wide variety of useful tools that are often very similar to PhotoShop. For the most part I like PhP9. There are two areas in which there are significant differences in capability. One is plug-ins. PhP9 will take a number of PhotoShop plug-ins but many don't translate. That's also true with other photo software. Adobe will continue to change and refine the plug-in protocols, so even earlier versions of PhotoShop may not run them. Since this isn't open source code, everyone else will be playing catch-up.
A more significant omission in PhP9 is the ability to do "actions." These are like "macros" or batch operations in other software — allowing you to do common procedures over and over again, without actually walking through all the steps. I and others have discussed this in detail in previous threads. Whether this is important for your particular needs is something you will need to decide.
