[Sticky] Not getting enough colour in my final integrated stack, how to increase?
Since then I haven't seen any complaints regarding this so I'm assuming it became better. 🙂
I experienced better colour data in the stack when NOT using LNC, untick "local normalization rejection" in (6) and when NOT ticking neutralizing background in (5).
To me it seems that these three options reduce/flatten the colours in your stack. I guess any software has a hard time distinguishing between wanted signal and unwanted noise/light pollutin.
And: I do not stretch my data in APP, but in Photoshop (I only use the light pollution, background calibration and star calibration of APP).
LNC normalizes the background very nicely for all stacks, resulting in a much more even frame. Neutralize background in 5) can actually influence nebulosity, but you can fully restore that when calibrating the background in the tools 9) menu. On the right hand side there are presets for stretching and lower down for color saturation, where you can saturate with protecting the background.
A more detailed explanation of the right hand side can be seen when clicking the red question mark.
Here is a link I did on FB and need help with the same issue. https://www.facebook.com/groups/630922131094037/permalink/844890496363865/
I can't access that group as it's private, can you post the screenshot here?
I am new to APP and it is probably something I am doing wrong but thought I would post here to see. The image was taken with a canon 60da.
So you left everything standard and the data should be from a color camera I assume? If so and you do see an RGB spectrum (top right, red blue and green graph) you may need to add saturation. On the right side of APP you have a switch to turn on saturation. Then under that there are sliders called "Sat." and "Sat. Th.". Sat is for the amount of saturation, to the right adds more, Sat. Th. is the lower threshold protecting the background noise from being saturated.
No problem, otherwise I'll have a look at processing that data as well to point you to some things maybe.
Hello Vincent, I made sure everything was default and went thru the whole process again and everything seems fine, getting plenty of color now, not sure what is different this time but I really appreciate the fast responses. I purchased APP full version a few days ago and I am sure I will enjoy using it, thanks again.
