Joseph,  I, for one, am glad of the change from a set schedule purely for selfish reasons.  My Tuesday work schedule offered no opportunity, other than taking a day off of work, to participate.  Now, at least, I can try to actually participate in one of these training sessions live!  Once again, there is always something I really wasn’t aware of or really understood the use of that I picked up in one of these sessions.  This time it’s the use of Grain.  Thank you for that.  The Dehaze slider is very useful for clearing out haze  but like all sliders can get garish if over used. I will add haze into a photo (move the slider to the left) if I want to give it a softer or misty look or to emphasize that effect for mood purposes. I also created an adjustment preset for one of my non-Canon lenses to correct for significant chromatic aberration effect and use that preset on import every time I use that lens so that way I do not have to do it on every picture one at a time or synched after import. I believe Aperture had that capability, but it’s been such a long time since I used Aperture that I can not be certain.  Looking forward to more of these as they come along.  Cheers.

Florian
