  1. 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.
  2. I think in general when you work with HDR images with 32bpp it will be slower than when you work with a 8bit formats. Question is if this speed can be improved on a software side or is it a hardware issue. When I edit 2K or 3K hdr images switching to Tonemap persona is not so slow. It is still not 1 sec wait like when you work with Jpg but it is acceptable. But I am interested if we can get higher speed improvement with bigger resolutions because in this instance I have to wait much longer. On the forum stuff members write that they are generally working on speed improvements on both platforms [PC | MAC]. I am looking forward for that. Other question is, if we can get better performance via hardware than which parts should we look at to buy ?
  3. Hi, this is my first topic on this forum. At first I just wanted to say that I am very happy with your product and I am very surprised that I am using it that often. I did not expect that. I thought that Affinity will not replace Photoshop in my workflow that soon. Good job. I am using Affinity Photo mainly for postproduction of my 3D renders. I love to use your Tone mapping persona which gives my renders a nice kick. Lately I work with 6k and sometimes even with 8k images and I import 32 bit EXR formats. When I open Tone mapping persona I have to wait really long time to start it up. Also other tools are little bit slower. I want to ask if in future we can expect some speed improvement with this bigger image formats.
