gradient exterminator questions

Been collecting data over the last week in the moonless and cloudless Melbourne nights, but light pollution is a real headache, esp when you live 10 kms from the city.
Anyway, been reading up on simple gradient removal tools and looked up a few video tutorials on line.
I am looking at Gradient Exterminator plug in for Photoshop. Looks like a simple to use product (if somewhat sensitive) and got a few good reviews.
so now a few questions:
Any views on this plug in from long time users?
Any new versions of the product or has it been "static"?
Assume it will work for DSLR and CCD images?
Anything else I need to be aware of?
Thanks
Bo

Bo, I use it all the time- does what it says on the tin & does it well.
Easy to use too

Hello Bo,

I use gradient exterminator - but I find it is best for uniform gradients, especially vignetting.
For uneven/variable gradients I use a free program called fitswork4 - it's gradient control is excellent and it has good ability to choose multiple areas that you don't want to include in the calculation (like faint nebulosity)..
It's free - so it's worth a try.


Tony.

I've used GEX for a long time. Sometimes it does seem like the settings can either be a bit too much, or not enough. In those cases, however, I've found that I can use a mask and apply exactly what I want (and where, if necessary). I'd be unhappy not to have this tool.

Thanks Tony, I will give that a go.

Thanks Peter, I have been using the Background Compensation function in Images Plus, which seem to yield similar results. Still learning the masking functions in PS too.
