Greetings! I love the power and control that using the Tonemapping persona provides with single image editing. But I'm concerned that it is so slow to go into the persona that it hinders my workflow. Once it gets into the module it moves quickly but it lags again horribly when applying the change. I'm using 188.8.131.52 The files I'm using are from a Canon 5DSR, and I go to 32bit Adobe RGB straight from the raw engine. The System is an i7 8700k 3.7-4.5GHz CPU with 16GB 3200 speed DDR4 RAM. NVIDIA GeForce GTX 1080 Ti 11GB GDDR5X GPU . Running windows 10pro. The performance monitor shows it is spinning at 16% (1 core 4.5GHz) and not using any disk. Are there plans to improve the parallelism and overall performance of this wonderful feature? Thanks!
Hi, I have question about the Tone Mapping Persona tools which I really love. I would like to better understand what is happening under the hood when using Tone compression tool and Local Contrast. Usually for realizing what some tool does I use SliceTool in Nuke, which shows me what is happening with the curve after using the tool. On images below we see what tonemap tools do to the curve of the linear gradient ramp. Some results are pretty crazy like when local contrast is combined with Tone Processing. I thought that if I apply same curve as I got from Tone Processing with a normal Curve Adjustment I will get same result, which is not truth. Here is an example. I would like to know what is happening to the image under the hood with Tone Processing and Local Contrast. I am curious if this effect is possible to replicate with other adjustments or tools. For example lately I use 3DLut Creator with Affinity, I am interested if this effects are possible to recreate with tools in 3DLut Creator and save it to .cube file. If anybody knows more about this topic please enlighten me.
Had a play with the HDR feature. I loaded 5 Pentax RAW files. Once Affinity had finished processing, I selected the high contrast black and white option. So far, so good. I then applied the Dodge brush to emphasise a line of mist in the landscape. If I then export to jpeg and resize the image, I end up with some cyan dots near, but not under where I used the brush. (jpeg quality 95%). This doesn't happen when not re-sizing, and when I didn't first use the dodge brush. If I recall correctly the problem remained even after I had gone back on the History tab to before using the Dodge brush. I tried to attach the original sized jpeg - not sure if it attached or not
