If you have hands-on experience with RawTherapee or have already evaluated it, do you think it is a good complement to RegiStax for AP image processing.
(Last step) Transform tools, if needed – to crop, resize (with Lanczos method), rotate, flip, etc the image.Again, the images in the attached album illustrate the process effects. removing automatic dead pixels and changing the exposure, sharpening, removing scratches and dust marks. (Next step) Wavelets Chroma contrast module – similar to the luminescence side, the chroma contrast module is used to reveal hidden colour data and/or sharpen it, by adjusting 7 wavelet layer sliders. While you may prefer to use RawTherapees normal noise reduction and sharpening, I prefer to do this on GIMP, as I think GIMP does a better job at these two.The "before" image is the one that came out of the RegiStax Wavelets process (denoise, sharpen filters and sliders) and the "after" image is the sole effect of the RT deconvolution tool process. It is applied to the raw file immediately after demosaicing and modifies the data in linear gamma to limit halo generation. My before-and-after-deconvolution images in the attached album illustrate the significant improvements delivered by the deconvolution tool alone. The Capture Sharpening tool helps recover details lost due to in-camera blurring, which can be caused by diffraction, the anti-aliasing filter, or other sources of Gaussian-type blur. The second tab allows you to control detail, sharpening, noise reduction etc. It's best to be conservative with this step and use a light touch.
Rawtherapee sharpening software#
(First step) Deconvolution (RL) sharpening tool – it is an iterative procedure for recovering an underlying image that has been blurred by a known point spread function (Wiki). Rawtherapee is an Open Source Software raw imaging program which can be. Pre-sharpening and noise reduction are the last steps before you convert and export your RAW image to the raster editor.In this experimenting I used RT mainly for: I didn’t use RT for the luminescence side though as I am handling it with RegiStax Wavelets. It caught my attention because it provides a Deconvolution sharpening tool using the Richardson Lucy algorithm and because it makes an intensive use of Wavelet contrast processing for both luminescence ( L component) and chroma ( a and b components).
Rawtherapee sharpening free#
RT is a free and open-source software that’s been around since 2010. I’ve been experimenting the past few days with RawTherapee.
