Thinking of subjects for RT videos is hard for my aged brain - so if anyone has something they would like to see a video on in RT or RT/Ps integration workflow then please let me know.

Iāve seen perhaps more than 10 of your videos but not all, so forgive me if this has been covered, but Iād be interested in your process for setting mid grey, and subsequently highlights that clip due to processing (not blown in raw). Eg. Do you raise exposure so focal point is roughly Middle grey, and if doing so pushes highlights beyond clipping, what tool do you use to bring the detail back - dynamic range compression, log encoding, tone mapping, something else? Also, do you care if only one channel is clipped, or only when all three? Iām thinking particularly of Sunrise/sunset shots with sky. The temptation is to increase saturation and bring out the pretty colours, but being bright, it can quickly push beyond clipping.
Fantastic work on your videos to date!

Hallo Andy,
I suggest a video on the new āCamera-basedā Perspective correction in latest dev builds, as there is no description yet in the wikipedia. The auto method works great in a lot of photos. For manually correction to draw lines one must hold the Ctrl-key and draw lines as far from the center of the photo as possible (vertical and eventually horizontal) and then click the apply button. Donāt use autofill but crop later, as one can shift the boundaries vertical and horizontal, and there is also a recovery if the image doesnāt fit with the correct parameters anymore (i.e. the distortion was to much as to be realistic on the image)
I think this will be of great value for land/cityscape and architecture photographers. Your videos are very good. If you need images for perspective correction, I can easily sent you some good ones (and also some where the auto correction doesnāt work).
Greetings,
Reginald from Bruges, Belgium (user of RT since version 2!)

Hello Andy
I am a bit ashamed to ask because I should fix these problems myself when I take the photographs of my macro samples at workā¦
In essence, I would like to know how to fix, with RawTherapee, the areas of my fruits (mostly peppers, eggplants, red apples etc) where, due the powerful light of the Elinchrom lamp, I have lost their true colors. Their pixels are āburntā and no longer available.
At present, I work with Gimp (its clone tool) to fix these areas but, perhaps, there is a way to fix them directly within RawTherapee, e.g., with the local editing tools available with the 5,9 upcoming next versionā¦
Here is a problematic picture (the black lines show the areas to repair with RawTherapee):
Here is the original RAW image (Dropbox link):
EDIT:
I forgot to mention that it is also possible to āspot removeā these areas with ART 1.6.1, a recent fork of RawTherapee by Alberto Griggio (kudos to him as wellā¦):

How about the proper use of the several methods to enhance acutance in RT? I mean these tools: Capture Sharpening, Sharpening, Microcontrast and Wavelet Levels Edge Sharpness. All (or some) working together and alone. With and without resizing.
What about a full processing of an image from color raw to B&W with the several tools available to help with that?
