Anyone have a good way to remove filter spots
 
I really struggled trying to remove the lens filter flare in this shot. Anyone have a good way to do it.

This was the best I could do.

Frequency separation is your friend for this problem which separates colour and detail into separate layers. Often used in portrait retouching to reduce details in skin, for your problem you want to remove unwanted colour on the colour layer.

If you have not tried it before it takes a bit of setting up but there is lots of info on the web on how to use frequency separation. Here is an example using it to remove lens flare:

In Lightroom, this is what I did. Two steps.

In Develop mode

Select HSL / Colour - section in tools drop down.

Select the targetted saturation adjustment the small target. top left of this tool.

Then put the mouse over bright red flare and press left mouse button and hold while dragging down until almost white.

Then select Spot removal brush sized just a bit bigger than the flare and click once on the flare.

That's it job done kind of.

Select the manual saturation adjustment the small target. top right of this tool.

Thats it job done.

Nicely done :)

Brilliant guys thanks. I knew that there would be much better ways to do it than I used. Will give them both a go myself *chr*chr

Here is my attempt.

http://www.e-group.uk.net/gallery/da...95-2_edit1.jpg

Done in Photoshop Elements 12. I defined four masks: the top half of the bright red flare above the tree, the half below, the "shadow" from the flare to the right and down, and a sliver along the top of the hedge on the right. The first three were all circular (with bits removed where they intersected) which made it easy, refined by adding a 2 pixel feather and shifting outwards slightly. Add each mask to a Huse/Saturation filter. Select the "red" channel, then use the eyedropper to refine the colour by selecting the colour of the flare in the picture. Reduce the saturation and lightness keeping just a hint of the red - as we are not after black and white. Then shift the hue a tad from red to something that approaches brown so it blends in better. I chose different masks for the 4 main flare areas as they needed different adjustments. Finally I flattened the image and just pixel tweaked it where the top half of the main blob was by cloning from either side just to enhance some detail.

Dave, I just had a go at your processing routine as it was in Lightroom and the easiest to have a quick go at. To be honest with my poor processing skills it was the only one I thought I understood. Anyway so far I've failed miserably to emulate what you did. When I select the flare and drag the mouse down the red spot gets redder! even if I drag the mouse upwards it never goes completely white. If I move it too far it starts to remove Orange from the whole image as well. Then when using the spot removal tool all I get is a cloned area to the side of the spot superimposed over the original area. Clearly I'm not following your example correctly but I can't work out how I'm doing it wrong!

Not sure what is happening.

Make sure you click on the little target in the saturation tool ( see arrow in pic below)

Then simply click hold and drag down on the brightest part of the flare until it loses most of its colour. You will see some of the sliders on the saturation tool automatically move left. Don't overdo it or the rest of the image will change colour.

Then in the spot removal tool make sure its got a good feather I think I used about 30% and the size should be about twice that of the brightest part of the flare. Also make sure its set to Clone not Heal.
It does actually clone a section from the left of the spot which you can move about if you drag the source around.

Hope this helps

Yep thanks Dave I hadn't got the section expanded and it was set to luminance not saturation, plus the spot was on heal too! haven't managed as good a clone insert as you did yet but I guess that just takes a bit of fiddling. Thanks for the help. I've learnt quite a bit this morning *chr
