Blur Filters?
Does this software have a blur feature and if so can it be used in conjunction with a gradient?

No, it doesn't have one.

Negative Clarity can be used as a form of blur vie a layer and will work with any mask as far as I am aware.
Whether that will give you what you want only you can know.
Selective noise reduction may also have some blur effect due to the nature of what it does.
Beyond that you really need to use a product with graphics editing options.
HTH.

Thanks guys. It is what I thought but thought I would just ask the question.
One more question. Is there a simple way to establish a colour cast in an image other than just looking at it?0 -

An unintentional colour cast I assume?
You can play around with the white balance picker on white, mid-grey and black areas (or areas that look like they should be white, grey or black) so see if you get an instant visual feedback of something that looks like a cast that might be lost i the colours. You may need to sample several different places.
You can also use the colour read out above the viewer and look for a consistently higher than expected value for one colour at most cursor locations as you move the cursor around. They are both quick and visual approaches.
Otherwise interpreting the various Histograms may help but may take a little time to become confident.
I'm sure others will be along soon with their own favourite ways of assessing an unwanted but not very obvious colour cast.
If you know you are likely to have a colour cast - possibly due to the lens in use for example - then the LCC tool would be something to investigate.

Because color preferences are so subjective, and there are so many variables, it is challenging determine where a cast might exist, other than looking at it. Doing things by the RGB numbers doesn't always translate into a pleasing image to look at. You can use a color checker/grey card to choose your white balance, but often I find images end up warmer than I prefer when doing so. You can use a color checker and build a profile based on the specific lighting in the scene, but this will not guarantee the colors in your image will be true to life either.
That said, perhaps you could use the auto levels tool as a way of determining if there is a color cast. Go to the preferences - exposure tab and set Channel Mode to: Red, Green, and Blue Channels (you don't want RGB channel). Then press the A on the levels tool and compare before and after. When scanning film I'd often end up with very strong color casts, a quick auto levels often takes care of the cast or gets pretty close. Again this is not going to work on every image.0 -
Thanks for your all your advice guys...Pete 0
