Regarding the glare effect, I'm wondering why the number of blades is always even? That is, if you put in an odd number the result is doubled.
I have seen pictures with real cameras that had odd numbers of blades in their irises, notably 5 and 7. This results in glare and bokeh with 5 and 7 spikes/sides. It's not common. I mostly see 6 and 8.
I'd like to suggest that odd numbers should be allowed. (if this hasn't already come up somewhere that I didn't see, I did search a bit)
Also, how about an added parameter - rotation - so that one can orient the spikes away from perfect alignment. Something that makes an image more realistic is that it isn't 'perfect'.
In thinking about this, I'm also wondering about bokeh and flare effects? Any thoughts/plans on implementing these real world effects?
I like the lens effects that are available. They really help make an image look photographic. It's just one of the many features that drew me to Lux.
