I’m pretty sure RT is limited to one graduated filter per image… but I’d like to be able to use two or more.
I’m new to RT. I currently use ACR+PS CC to process raw NEF files from a D810 and Ricoh GR files (DNG). Tried RT just to check what was out there in Open Source and was astonished by the quality of it’s raw processing and the depth/maturity of some of its processing tools.
Wavelets and the CIEC Color Model adjustments are standouts. I process both in ACR and PS using the LAB space until the final output stage (to avoid color shifts and to improve the operations of both USM and “Smart Sharpening”). RT seems to offer still better tools for this kind of processing.
I can see that RT hands off to image editors for post processing ‘touch ups’ (e.g. dodging, burning). But I also use a graduated filter/brush in ACR on many images at an early stage of processing to (subtly) refocus and sometimes exaggerate the lighting across the image to help direct the viewer’s attention. Often, this involves two or more graduated filters (ACR has a very flexible options for the gradient including exposure, dehaze, contrast and color temp. but exposure is probably the most important of these).
RT seems to have just an exposure gradient. That’s good. But I’d really like to place more than one per image e.g. in different corners of an image with a central lighting focus. This is much more subtle than using e.g. vignetting (which is often obtrusive).
Has this been considered before? Is it a possibility?
