Part of #Brunnsviken north of Stockholm #shotonlibrem5 using the #megapixels #camera app from https://source.puri.sm/dorota.czaplejewicz/megapixels with default settings in #PureOS byzantium. The image file ended up as a 2463552 bytes .tiff file in ~/Pictures/ which I then made into a .jpg file using the "convert" program. Maybe @dos knows tricks to get better image quality? 🙂 (One issue seems to be that bright areas get too bright.) #librem5 #freesoftware @purism @martijnbraam

I don't know why it happens but it looks like that pink color sometimes appears in at the change from "too bright" to some normal color, mostly when the change is abrupt from one pixel to the next, when the change is more gradual it does not seem to happen.
Here is another example where that is seen more clearly. This was taken earlier in the day when the daylight was a bit brighter (still no sunlight though).
@eliasr @martijnbraam @purism That's typical for overexposured images. Can be corrected in dcraw by adjusting -H option.
@eliasr @dos @purism @martijnbraam yeah it looks more like what u get from an overexposure highlighting option rather than chromatic aberration. Was it present in the tiff too?
Yes, it looks that way in the tiff too.
There is also corresponding a .dng file for each photo taken, that I think contains the "raw data", probably I could process that myself to create images but I did not try that yet.
@eliasr @purism @martijnbraam Not everything needed for nice full-res photos has reached the repos yet, it's very fresh. Also, you need to adjust gain and exposure settings manually while taking photos (there's no auto mode atm) to avoid over/under-exposure; and same with focus.
