    Hi Tom,

    I think that both, sharpness and noise, are definitely ok. The wall is not really suitable to judge it properly, but neiter are responsible for the problem of not aligning. How do the neighboring shots look like? Because I think it should just be possible to align it with a suitable neighbor - there are few features, but RC should be able to pick out enough...

    That's a load off my mind about sharpness and noise - thanks Gotz. Didn't look good to me when zoomed in on screen to visible-pixel scale.

    So back to neighbour/coverage - for another thread.

    No problem. Glad to unburden you!  :-D

    I already suspected that you are over-worrying about that...

    If it looks crisp at 100% - it's sharp. If you think " where are my glases" or you want to squint your eyes, it's not sharp.

    There are examples here in the forum where people wonder why something doesn't work weel and whe I look a the pictures you can sometimes already tell by a large thumbnail, that it's super blurry...  :-)

    Oh, and if you really want to see how well your camera deals with noise, you need to take a picture of a black surface, non-reflective that is...

    Nice one. How about a photo with the lens cap on?

    I fyour camera can focus that close, then why not?  :D

    No seriously, it needs to be homogenous - just like the comparison I linked to once, there you can see the most noise on the black surface...
