And just it was unclear to anybody else - it is still a Photoshop plugin!


PS I see on my computer I'm getting various 'generations'of some Topaz plugins. Once I have downloaded - say - Remask 5, is it ok to go and delete Remask 4 and 3 - or might dreadful things happen.....
?

Yes it does.

However.

Results still vary depending on the image. If you have an image with good contrast between the subject to be isolated and the background the results are excellent. If you have a green object on a green background it won't give good results. You also have to know how to use it because there are tricks to refining the edge and also a bit of work involved in getting a good edge but if you take time it can do things that you couldn't do with the native tools in photoshop or lightroom.

It's basically the same software that used to be called Knockout 2 way way back when Corel owned it. I loved it then and was disappointed when it stopped working in Photoshop (I think when it went to 32bit or 64bit something like that) I looked for a long time for an upgrade for it since it's the best knockout tool I ever used. I was very happy when I discovered remask. And I'm not paid to say that.

The fact that the program works now also in standalone mode is quite useful, both for people who don't own a Photoshop or even for isolations and simple compositing which could be now done on a separate computer without Photoshop. Using Remask 5 in standalone mode, you can cut out an element quickly from an image, finetune the mask, and then replace the masked out portion with white (or any other color), or with another background image, such as clouds or water. The final composited image can be saved as JPG, TIF or PNG file.
