  1. Getting help from Topaz Labs is liking talking to a wall. They brought in a new operations manager, Eric Lowery, and he made encouraging words about cleaning up the mess, but I am seeing no improvement in their responsiveness.  I send them emails requesting help and I receive an automated reply acknowledging that they received my request, but it takes a week before I receive an answer to my question. And, if their answer doesn't solve my problem, it takes another week (if I am lucky) and so forth. I have a chain of emails going back to 8 October (before Catalina) trying to resolve the plugin problem.  

    I loaded their AI plugins into Affinity Photo and they show up under Filters > Plugins, but when I try to use them nothing happens; they don't even start-up.  They do work as stand alone but not as Affinity plugins. And, yes I did restart Affinity Photo.  I am using Mac OS 10.15.1 and AP 1.7.3 on a 2019 iMac and I have the latest versions of the plugins.

  2. At a qualitative level your explanation is quite good.  However, this is not what is actually happening at a statistical level.

    Here is a copy of a paper written by John Paul Caponigeo (Use Multiple Exposures To Reduce Image Noise, December 13, 2017) in which he describes what goes on in Photoshop.  I assume AP behaves in a similar manner.  Occasionally I have used multiple exposures for star photography to reduce image noise in both PS and AP, it works.  

    "So what is Photoshop doing? Photoshop first aligns a series of images as separate layers, converts them into a Smart Object, and blends them, reducing or amplifying the differences between the layers with a variety of rendering modes. You can choose one of eleven rendering modes; Entropy, Kurtosis, Maximum, Mean, Median, Minimum, Range, Skewness, Standard Deviation, Summation, and Variance. Few people will ever use all of them; most won’t use any of them; but I recommend you try two – Median and Mean. (Stacks were designed for analytical tasks in various scientific fields, like astrophotography or forensics and they’ve since been put to many other uses.)

    Median and Mean select values in between the highest and lowest values, smoothing out the differences between aligned layers in a stack. Median works best for images with some motion, either subject or camera, to remove moving objects or noise. Mean works best for processing exposures without motion. (Astrophotographers typically make many exposures, sometimes dozens or more, of the same subject and use Mean to reduce noise.)

    The more exposures you make and combine the better the noise reduction. Only practical limits apply. How many exposures can you make? How many exposures can Photoshop process on your computer? You can stack and process as few as two images. Three is my recommended minimum. Six is better. After that, you get diminishing returns. (Try using your camera in burst mode more frequently.) The most challenging part of this technique is identifying situations where it’s helpful and remembering to make multiple exposures. If you have the exposures you can take advantage of this great feature; if you don’t have the exposures you can’t."

  3. Let's assume that I have 2 copies of the same image.  I will call one image "clone 1" and the second image "clone 2".  I would like to be able to place both images into AP such that clone 1 is on the left side of the screen and clone 2 is on the right side.  My goal is while doing a dodge and burn on clone 1, I can look at clone 2 and, by comparing the difference between the two images gauge my D&B progress.  I do not want to do this with a split screen because I want to be able to see both images at once and not have to move a slider back and forth.

  4. I am doing Dodge & Burn with 50% gray scale mask.  Carl Surry did an excellent tutorial fro this process based on translating a PS tutorial.  Other achieving the 50% gray scale, the PS tutorial is fine and Carl did a very good job showing how to get the gray scale with AP.  

    In the PS tutorial, the author showed a split screen; the gray scale mask (he called this a "visualization layer") next to the Pixel image.  How can I get the same side by side view in AP?

  5. You guys are number one on several levels, your products are great, your tutorials are among the best, and you are continuing to expand your product line, keep it up.  However, as you increase your product line, the "desktop forum" is becoming cluttered.  For example, when I have a question, I am forced to wade through inquiries regarding Publisher, Designer, and Photo (thank you for separating iPad and Beta).  I realize that Serif has intentionally created products that are are inter-related and have much in common, however from a user ease of use prospective, I think that the time has come to have a separate forum for each product line.

  6. I went the direction that you are going, replace Acrobat with something else.  PDFelement turned out to be a fairly good replacement for Acrobat Pro 10.  That was the good news, the bad news is that their (Wondershare) customer support is amateurish at best.  They reply to your requests BUT they never seem to answer the question you ask.  It may be a language problem, they are a Shanghai company.

  7. You guys are doing a great job with 1.7 beta.  

    I have two questions:

    When do you expect to be making a final release? 

    I received this reply to an earlier posting, "Currently Affinity Photo doesn't pass the colour profile info to the plugin thus the differences you are seeing. This is more obvious when using wide colour profiles as the ProPhoto RGB you are using."  Will the final release be able to properly handle Pro Photo RGB?
