Suggestions (or directions)

Hi Adam - not sure if either of these is currently available somewhere.  If so, please direct me; if not, consider them suggestions :)

1. Do you maintain an email list so that subscribers can be notified of new videos in the areas they are subscribed to (obviously to prevent having to keep checking)?
2. Although I know you don't typically shoot OSC, for those of us that do (I use a ZWO ASI071Pro), do you have or would you consider doing a video on the merits of creating a synthetic luminance, and if it does have merit, how you would construct a workflow to process this in PI (which seems to have some processes that can be directed at "lightness" via a check box, which might obviate the need for synthetic luminance processing).

BTW, I have learned so much from Fundamentals and Horizons....thanks

Ed

    Hi Edward,

    1. I guess that is what this forum was for. I always announce on here when I release something I also always post it on the members' page (the first page you see when you log in) and finally I post on the AdamBlockStudios Facebook page. You might be able to have the forum send you e-mails? (I am not certain...I would need to check that). 

    2. I think this requires a longer answer- but basically I would say a synthetic luminance is helpful when you want to travel a different path than is possible on the combined or individual color channels. Take deconvolution, for example- you would definitely want to perform this on a properly made synthetic luminance. You would also want to have a synthetic luminance if you were blending something together in either the color data- or luminance image- but not both. HDRMT, as another example, you would only want to perform on a luminance image- not on a color image, because it will make things lose saturation (go white).  But basically it depends on the path of processes that are followed to reach a particular place.

    I suspect that isn't a very satisfying answer... so I will tuck this suggestion away. 

    One thing that does interest me... more immediately, is filling big obvious holes in Fundamentals. I would like to take care of those... and then concentrate on Horizons.

    Thanks for the reply.
    As for the synthetic luminance question, you are very perceptive...not very satisfying.....but no fault of yours.  I will patiently await a future video (I'm sure you have great sources of data, but if you ever need any OSC data for such a video let me know).  In the meantime, I will start playing around with it on my own, starting with deconvolution, and see how it goes.
    Thanks again.
