Hello, I am new here so I suppose the best thing to do is introduce myself and let you all know what my topic is about. To begin, I am a professional landscape and nature photographer. I create HDR composites that I sell through stock agencies and also in local art galleries in Sedona and Jerome AZ. For many years I used Photoshop CS5, and it did what I needed done as far as image manipulation and editing. But a short time ago my old MacBook running Lion OSX failed. The GPU in the logic board burned out and I got the white screen of death. I wanted to get it fixed but the parts were no longer available, which forced me to buy a newer Mac running High Sierra 10.13.3. PS CS5 does not work well on High Sierra. It would not update and it often crashed with errors. Adobe technicians told me that CS5 had never been tested on High Sierra and probably would not work. They advised me to get creative cloud, but I told them I was not going to rent a program. I only buy programs with perpetual license. I found Affinity Photo while searching for CS5 alternatives. I have been testing Affinity for the last couple of days and so far I am impressed. It has many of CS5's capabilities, but the controls will take me some time to get used to. I will probably end up buying the program when the trial period is over. But there is one thing that does need improvement with Affinity. It need support for the JPEG2000 format. I have several hundred images stored in that format and Affinity cannot open them. I use the JPF format to archive my master copies after all editing is finished. I put them in a folder with the original camera raw copy. The reason I used this format is because it supports LAB 16 bit color, just like a TIF, but has lossless compression and has half the size of a TIF. This format is also being used in some video applications. Since Photoshop supports JPEG2000 I think Affinity should consider supporting it as well if your company wants to compete with Adobe on their level. I can use another program called ColorSync to convert my old JPF files back to TIF but that might degrade their quality. So if you are considering adding JPF support to Affinity please let me know. And if you're interested in seeing some of the work I do here is a link to one of my portfolios. The images on this site are being marketed through Getty Images. My HDR lightning composites are my biggest sellers. http://www.roomtheagency.com/profile/555/ Thanks for listening.
