about (my) reviewing in QI

dust spots ..

I'm well aware that my frequent remarks about dust-spots easily give a nit-picking impression. But I suppose, that just like me any other committed photographer tries to post pictures as perfect as possible; And I think that you too would be displeased if you look back in some years and find so annoying flaws such as dust spots in your appreciated QIs.
I suggest that 'review' should not only be seen as confirming: 'complies with the QI-standards', but also as the last chance to check for small errors wich can easily happen in enthusiasm for our good pictures. Therefore we could accept a not so ~~blind as a bat~~ lazy reviewer as assistance by honing our marvellous pictures.
So please have a little patience with me and my remarks,

And BTW: if there was a dust spot on one of your pictures, do you really believe this speck of dust lingered on your chip for just this fraction of a second? - maybe it might be a smart move to check the full set of these images PtrQs (talk) 16:17, 28 March 2019 (UTC)

.. and how to find them

If you can edit the picture the easiest way to increase their visibility is by playing with the contrast in your picture. By raising it - above any sensible level - and adapting the brightness you will plainly see them.

And the best way to spot them is by choosing a magnification so you can see only a part of the picture and then continuously moving the cut in your window/frame. The human eye is not bad in recognising patterns, but it is much better in spotting a moving change. (And for not loosing that lousy dust spot, I move it to that one defect pixel on my screen, so I will re-find it after changing to edit/clone mode.) --PtrQs (talk) 23:20, 19 January 2020 (UTC)
