Hi Guys, well i do know how to take flats, but is there a level of consistency in the final product, and when is the best time to take them if not using a light box.
With consistency i mean is there a certain shade of grey, or for that matter a certain shade of anything.
Last night i took three sets, first i waited for the sun to just set and covered the scope with a white material cover that i made, that set came out mid tone grey.
The next set was about 15 minutes after sunset, they came out quite dark grey.
And finally the next set i took well after sunset,with no white cover at all, and they came out a medium bright blue.
I presume blue is no good, but what is acceptable in the tonal rang of grey's, and when is the best time.
Thank You for your comments in advance.
