Hi @gbrowne
I use the default camera app that comes with /e/. I took a sample photo for you using max resolution (3840x2160 8.29MP) and zero decompression. Results below (not sure if the forum software will compress the images - but all the figures are there).
This week’s Development Update post mentions that the default camera app is being improved:
I dont know about ADB getting ported to /e/, maybe @Manoj would know, but it looks like /e/ is investing in improving the default camera app anyway. I personally dont use advanced camera options (hdr, exposure etc), I just want a camera that focuses accurately really quickly and takes a good photo straight away.
