+Derbyshire Dave Posted October 23, 2022 Share Posted October 23, 2022 Stu, I think you did a great job there.. I think that there are some improvements that can be made to winkle out a better shot though. The colour balance is out, so what I did was to use levels and curves in Photoshop to balance them out. This is the result.. What I did was look at the original histogram, which looked like this.. I first of all went into levels. I selected "blue" rather than "RGB" and "nipped in" that gap at the left hand "black point" side or the blue graph. I then went into curves slected green and stretched it upwards a bit, and blue and stretched it down a little bit. The final histogram looks liked this.. Which is not perfect, but a lot more balanced. This wasn't meant in any way to be a criticism, hope this helps. PM me if you need to discuss it.. +Glafnazur and +Stu 1 1 Link to comment Share on other sites More sharing options...

Clive Posted October 23, 2022 Share Posted October 23, 2022 With an image like that which is mostly sky background I will set the peaks of the histograms to the same ADU value such that none of the histograms to the left of the peaks are 'cut-off'. With my processing software that just involves offseting the RGB channels by a linear value but I'm not sure if it can only be achieved using 'curves' in other software? That normally gives a reasonably correct RGB colour balance starting point which can then be tweeked using curves. +Stu 1 Link to comment Share on other sites More sharing options...
