Yes, you can have multiple radial filters in the same image. Make sure you click the "new" tab to get a new filter, otherwise you are in "edit" of the previous filter.
The default setting for the radial filters is to affect the image outside the ellipse, thus multiple filters will conflict with each other.
Click on the "dot" in the image to activate the filter if you want to edit one of them.
Thanks for your response. I guess the problem i am having is the second i try to add a second filter, the colours and tones of my photo just go haywire and all dark. I think its too advanced for me so i'll just leave it at the one filter. Thanks.
If you're trying to adjust different areas of the image separately the Radial filter is probably not the best choice. What are you trying to do with the 1st and then 2nd Radial Filters?
Are you clicking on "New" at the top of the panel and then opening a new filter circle with its own black pin in the center, while the first circle's pin turns white (inactive)? You can't have more than one setting per parameter in any given filter; one Exposure setting, one Contrast setting, etc. Additional settings for the same parameter have to be in additional filter circles. Similarly, the filter can be only outward or inward, but not both. I have had images with nearly a dozen filter applications.
