Yes of course area of the lens not the diameter is the factor determining light gathering. There is a huge difference in light gathering between the two lenses and whilst the ISO is 3 stops greater on the slower lens, even given its slightly longer exposure; the light gathering of the 100mm f.l. Lens at the slightly over 1 stop faster aperture but 3 stop slower ISO is clearly a key in capturing more colour. Like I said in my other post in the other thread, I will experiment myself a little further.
Didn’t mean to hijack your thread, Paul. I do like what you’ve achieved in 5 seconds. A few of those stacked and it will be stunning as Raymo achieved with his. Well done!
