@Paule, really beautiful pictures.
Just two things to consider.
The camera has a resolution of 8 MP. So naturally not much “flesh” for zooming in. I actually think it’s pretty good for 8 MP. But I’m at your side, waiting for the upgrade.
The pictures are automatically heavily compressed when uploaded to this thread / forum. So the original quality gets lost.
The last three pictures I posted were done with Open Camera on LineageOS.
I must admit, that I usually take several shots and only keep the best one.
Macros are sometimes easy, sometimes difficult. Depends on the light, contrast and especially the size of the object.
When the camera cant get the correct focus, I let it focus at another object at the same distance, pan back to my subject and focus again. This way I often succeed when subjects are too small.
Did you change the resolution to 12mp? It seems like the pictures are the same size and resolution, no?
Edit: here’s the link to know how to change resolution: read section “after”, point 3
Ok. I am no specialist. I just saw that both pictures were around 2MB and that both were around 2440x3260, which is the size of 8MP pictures. That’s why I wondered. Maybe are the pictures compressed by the forum? Someone else should have an explanation to give us.
