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?

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.

My sincerest apologies for the delayed response. If you open your RAW file then navigate to View>Studio>32Bit and make sure this option is checked, then please provide a screenshot of this dialog in your app - it should look as below:

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.

Thanks for your further screenshots - I can see the 32bit setting is correct, so this may be happening due to your Windows Colour Profile in use, as Affinity uses this to convert colours in your open documents.

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".

Although that appears to have resolved the issue, I think that's just masking the root cause. From the description, it sounds like you're now using a monitor profile. I would leave that set to 'sRGB IEC61966-2.1 (Linear)'.

I would ensure you're on the latest version of Affinity Photo (1.8.0.585) and then try resetting Affinity Photo back to the default settings and seeing if the raw images still appear too dark in the Affinity Photo Develop persona (and what the title bar shows).

To reset Affinity Photo, close Affinity Photo, press and hold the CTRL key on the keyboard, then launch Affinity Photo whilst keeping the CTRL key pressed. When the 'Clear User Data' dialogue box appears, click the 'Select All' button at the bottom and then the 'Clear' button to clear all the user data.
