Ordinarily I do not think too much about dither settling time since it is such a small fraction of my imaging time. However, tonight I was just imaging a series of short exposures rotating through L-R-G-B and it occurred to me that it is unnecessary for SGP to dither every frame. The dithering is important between subs of the same filter, but not between filters!
Today SGP does this when “Rotate through events” is selected:
L
Dither
R
Dither
G
Dither
B
Dither
but all it needs to do is this:
L
R
G
B
Dither
L
R
G
B
Dither
…
My actual sequences often look like this: L R L G L B. In that case SGP should do:
L R dither L G dither L B dither …
I know some folks have very long dither settling times, and this optimization could make an imaging session much more time-efficient.
I don’t think so. We can look at “smart dithering”, but I think that event based dithering is too complex and not necessarily something we would like to support.
Ya… we can take a look at this, but it is more complex than it might seem at face value, especially since SGPro allows real time modification of events. It is certainly possible, just invasive. For instance, what if the L event suddenly disappears from the rotation? It is certainly possible to code up a whole rule set around when to dither, but it will probably be a bit of a chore to implement correctly.
Can’t we have a option in event settings for dither or not dither , would not seem too hard
default could be dither and its up to the user what option he requires , would also get round altering the sequence
