RawTherapee Dust Spot Removal on Steroids Using a Temporary Curve
@midnight-starlight asked a RawTherapee question about the spot removal tool.
The Spot Removal Tool in RawTherapee can be enhanced by revealing MORE spots and blemishes with the addition of a TEMPORARY curve in the exposure tab - a long-standing Photoshop method, and retouching on steroids!

@andyastbury Thank you very much for answering my question with this video. It's tutorial channels, in particular yours, that make RawTherapee a viable choice as far as I'm concerned. I really appreciate it. P.S. And thanks for the correction - You see the dust on the sensor, not the lens!

[@bernym4047]

Regarding dust on the sensor, I have a clip-in sensor protector which effectively is just a glass filter and therefor can be more easily and safely cleaned (e.g. with an air duster or brush) than the sensor. It's made by STC optics.

Thanks Andy, please continue with your RawTherappe videos, I've learned a lot from you!

[@AndyAstbury]

Thanks, will do! Is there anything specific you would like to see?

[@joseantoniolopezgomez-vazq4284]

​@@AndyAstbury Yes, I would write down a list but I don't want to cross the line, so I'll tell just some things. I would like to know more about capture sharpening, because I think I've heard you have to do that at the end, and don't know why. I also don't know anything about those advanced modules (Retinex, Colour Appearance & Lighting, Wavelet levels), they're something I don't dare to take a peek. And also I would like to know how to treat overexposed zones; sometimes you take a picture, and there's a massively blown zone you have to deal with because you couldn't take it otherwise. I hope you choose one or two of them for your next videos :)

And he is back with another RT video!

Hi Andy, thanks for the video, its very helpful again. For me it looks a bit complicated: while you fiddled the tonecurve, i just switch on the negative-film tool for removing the spots (may be adapt exposure for to find them) and then switch off the negative film-tool. Anyway, the perfect result counts, not the way how to get there. Pls go on with your great tutorials!👍

[@AndyAstbury]

Good point, but the Film Negative tool will not reveal them all, as it doesn't move contrast around. Using it with a small to medium curve shift would do the job a bit better.
