I reset Affinity Photo as you suggested and it is working fine now. Thanks for your help.

Thanks, Dan. I only use one monitor, an AsusPA248 graphics monitor which I calibrated with a Spyder Elite on 2 December, 2018. The ICC profile I created then is the default one I use for the monitor. In Affinity colour preferences I set the 32 bit RGB color profile to "sRGB display profile with display hardware configuration data derived from the calibration (linear)", and ticked off "Convert opened files to workspace". Files opened in Affinity Develop Persona now seems to be the same as in other viewing programs, so I think my problem has been solved. Thank you for your help.

Thanks for your reply. I opened a number of files with the 32-bit preview checked. Some opened with the window as you show it, others with all items greyed out. I attach three screen shots: two of the same file, before and after I pressed the blue Develop button (I am not sure what that button does as I did not see any difference in the photo?), and one screenshot where the preview is the same as yours. More of the files opened with the preview correct. When it is correct the photos look as expected. I just don't know why some are not open correctly.

Hi Dan, Yes, my results are different. I have attached screenshots of the picture as opened in Affinity and as opened in Irfanview. Also attached another picture as it opens in Affinity and the same one opened in Irfanview. The difference is striking: the Affinity is way too dark and the other looks normal. No editing done to either shots. I just don't know why the difference and I don't seem to be able to do any adjustments in Affinity to correct the darkness. It is the same with all other pictures I open in Affinity. Before I got this camera I used Lightroom 5 but it does not open the raw files from the a6600 so I can't compare directly. Any suggestions would be welcome.

I have just got a Sony alpha 6600 with the kit lens 18-135. When I open the raw files in Affinity, the pictures are extremely dark. If I increase the exposure, the highlights are completely blown out. If I open the file in other viewers, the exposure is fine. Since I am new to Affinity, maybe I missing a setting or something? I don't see the lens in the list of supported lenses. Is that the problem? I am attaching a file. DSC00221.ARW
