If the photos are already aligned then either 3.1.2 or 3.2Beta will reduce the ghosting issue if the Moving objects/people option is used. The aligment algorithm seems to be very good in 3.2 Beta and you may find that this could help your shots. This set of shots are like most of my shaots and taken on a tripod (I had to shake the tree to get movement). I guess your shots are handheld and that there are two issues here: 1) alignment to remove translation and rotation that occurs with handheld shots & 2) movement of foliage. You can see this in the shadow sides of the branches in the example above.ĭid you align by features? I'm not really getting the same results as above with my test image. ![]() It's interesting that there is a cost to increased reduction of movement artifacts - the more effective it is the less dynamic range that is included in the tonemapped image. Thanks so much for doing that research! I'm off to upgrade! If you are trying to do a grunge type HDR then I think the new Photomatix 3.2 Beta will give the desired results without the HALO effect. These images were from Photomatix 3.1.2Īn investigation into the new feature witch reduces Halo effects 'Attempt to reduce ghosting artifacts - Moving objects/people ' which appears to do the best job. If you have a HDR set where objects have moved then use the setting Not the best, and the name of the option suggested it would be the one to use.Īttempt to reduce ghosting artifacts - Moving objects/people īest choice for reducing ghosting artifacts. I was pleasantly surprised to see that it was possible to remove the moving foliage ghosting artifacts, but only by using the 'Moving objects/people' option.Īttempt to reduce ghosting artifacts - Background movement(eg water of foliage) The following shots show foliage that had been moving between shots. It appears that the 'Reduce ghosting artifacts' engine is the same as what is used in Photomatix 3.1.2. I was asked if there was any improvement if the handling of foliage that is moving. Trevor there is a link on the above picture along with more details of what I found by playing with the Beta. I will try some more test in the coming weeks. Photomatix 3.2Beta clearly does a better job of alignment then Photomatix 3.1.2 I also did an alignment test, the results can be seen here along with extra details.Ĭlick on the image to be taken to more details. Using 3 exposures of 15.1 megapixels in the HDR process and then tone mapping using detail enhancer the memory usage was reduced from approximately 456 megabytes of RAM under Photomatix 3.1.2 to just 406 megabytes of RAM under Photomatix 3.2 Beta. I found that the memory usage was reduced for the 'Detail Enhancer' mode. Alignment and HDR generation is also still single threaded. I use RAW and the RAW conversion is still single threaded (only uses one processor even if more are available). The multithreading support is in the tone mapping engines and does speed up the tone mapping process. ![]() ![]() It appears that there is no extra overhead in the multiprocessor (multithreaded) implementation as the total CPU time is the same but the elapsed time is reduced. This means on a dual or quad core processor that the software will use the available cores, this is a big improvement over previous versions that only used a single core. I was pleasantly surprised when I read that 3.2 BETA has multi-processor support. UPDATE - 3.2 Mac release available now for download from HDRsoft. UPDATE - 3.2 Windows release available for download from HDRsoft. I downloaded the BETA version of Photomatix Pro 3.2 today and started doing some testing.
