PhotoDante Posted December 5, 2016 Share Posted December 5, 2016 Hi there, After opening several raw files I found a problem with red and blue dots in Affinity Photo. The files where I found this dots are taken at iso 200 and different lenses. I'm photographing art, the first thought this must be in the painting. Opening the same files in Lightroom, Photoshop and bridge didn't show me the same dots. After exporting the same dots are in the jpeg files. What are these dots? Where do the came from? Am I the only onewho's facing this problem? Thanks in advantage.

emmrecs01 Posted December 5, 2016 Share Posted December 5, 2016 That's no option, I get the warning the file is to big ( 194 mb) Try zipping it or, more likely to be needed, upload it to a file-sharing site (Dropbox or similar) and provide here a link to it.

Staff MEB Posted December 5, 2016 Staff Share Posted December 5, 2016 Hi PhotoDante, Welcome to Affinity Forums :) These are called Hot Pixels and usually appear when the sensor becomes hot during operation or when using a high ISO (this is usually a temporary issue) or Stuck Pixels when some or all RGB components that compose a pixel become stuck at their maximum value (camera sensor - those may or may not disappear over time ). This is not directly related with Affinity Photo itself. If you do a Google search for these terms you should find plenty of info about those issues.

Staff Pauls Posted December 5, 2016 Staff Share Posted December 5, 2016 Adobe prouducts have some automatic dead pixel removal feature which Photo does not. If your camera has 'Dark Frame nose reduction' then that would help remove these pixels too at the expense of exposure time. Which camera is it ?

Mark Ingram Posted December 5, 2016 Share Posted December 5, 2016 Hi PhotoDante, we are looking at implementing an automatic hot pixel fixer in an upcoming release. In the meantime, you could use the blemish removal tool (with a 1 pixel brush size). You can also save the blemish positions as a preset, so you can quickly apply the fixes to all of your photos.

Thanks guys for all the time and efforts you spend in the forum :) hands down. My camera is a Canon 6D. I didn't think about the hotpixels.

Staff Patrick Connor Posted December 5, 2016 Staff Share Posted December 5, 2016 Thanks guys for all the time and efforts you spend in the forum :) hands down. My camera is a Canon 6D. I didn't think about the hotpixels. Not to worry, this will come up a lot I feel. Affinity Photo chooses to show the user all the data, but they are so used to some default noise reduction and hot pixel filtering (as in other applications) that they say we have bugs in our algorithm, where normally we can show the data is noisy or has dead pixels in the raw file. I believe there is even a tutorial on noise reduction in Affinity Photo RAW studio to explain our current approach.

Max N Posted September 4, 2018 Share Posted September 4, 2018 good afternoonIf the camera is a canon, that is, the procedure for treating the broken pixels.https://world-image.ru/kak-ubrat-bitie-pixeli-na-fotoapparate/ - here it is described how to get rid of them. In Russian. You can use an interpreter who is convenient for you. I was so clever removed the broken pixels on the 40D 50D 6D.I hope you will also help. __________________ Windows 11 64-bit, AMD Ryzen 9 3900 + Nvidia 1660 Super + Nvidia Studio driver + 32 Gb RAM.

tacua Posted September 4, 2018 Share Posted September 4, 2018 Rawtherapee has dark-frame which will remove them. You take pictures with the lens cap on, and then it uses that photo as a reference to remove the hot pixels. The Canon cure suggested did not work for me.
