Hi,

Where do I view the mask as depicted in the photokey tutorial?

file:///Applications/FXhome%20PhotoKey.app/Contents/help/key.htm

Composite Lab Pro has this option as well as every other key program I have used and I just can't seem to find it.

Thanks

That file isn't actually a tutorial, but rather a page of the help manual. I believe the "mask" you are talking about is in the section on Detail, where it shows black and white image of the alpha channel. This can't actually be viewed from within Photokey. The B & W images are just being used to demonstrate what the Details slider does as clearly as possible.

Thanks.

Kinda odd that a keying program doesn't actually let you "see" the key (alpha mask layer). Also a bit misleading with those pictures in the help manual as it had me looking for that mode for quite a while.

Does version 2 have this ability?

Sorry you found the manual confusing. A bit ironic really, considering the part that confused you was added for clarity.

Version 2 doesn't provide access to view the alpha channel either; I'm not sure what purpose it would serve, really. In the manual, where they had to show the difference in the Detail setting in a tiny image, the black and white shows it up better, but in the program when you are working at a much higher resolution that isn't really an issue. Of course, just because I've never found a use for it doesn't mean there isn't one, as clearly you have a use you would like to put it to.

Thanks for clarifying.

Sometimes when I pull a key it looks fine and then after I export I see a bunch of background speckles got left behind. I mainly export to png. Also the other day I had a slightly blurry image and the image appeared ok, and after the export and into photoshop it had a bunch of leaky spots on the ladies leg that were not visible in the render. Even after doing the same key again and looking closer those spots did not show transparency as much as when in photoshop.

It would be very helpful to see the mask for these situations.

Yeah, that makes sense I guess. Meanwhile, you might try adjusting all the key settings before bringing in your background, if you aren't already. Perhaps against the black canvas the wonky bits might be more visible?

So what is the masking feature that you are referring to in version 2? I didn't notice it on the product details page.

http://fxhome.com/photokey - third item over in the top row of features.

In version 2, you can add hand-drawn masks to either retain or remove certain areas, regardless of color. For example, if your subject is wearing a green tie, you can retain the tie while remoiving the greenscreen behind him. Or, if you have a heavy shadow in the corner of your greenscreen that tends to be disobedient when you are keying, you can remove it with a mask.
