Well, I know I keep writing about LIGHT Photography Workshops but I do have some other stuff in the pipeline, honest, and I will get to it. But, yes, once again, I want to spread the word about MNL from LPW. Every Monday at 6:30 pm Pacific for an hour or more. Costs less than $5 per session. Stunning value for the money. Hal Schmitt, fighter pilot turned photography pilot and amazing instructor. But enough of that.
Last night covered two curves topics I have been anxiously awaiting for a while: adjusting color casts separately for highlights and shadows, and ensuring that white seamless backgrounds in studio shots are white and consistent. This was the third or fourth curves adjustment layer evening, and each has been a revelation on my pathway from Corel's PhotoImpact (that I have used for ten years) to Adobe Photoshop.
We all know about the midtone color adjustment eye dropper in curves and what it can do for color casts. But there is also a technique, although a bit more involved and using the separate color channels that allows color cast correction that differs between shadows and highlights. It involves dropping color samplers onto representative areas of the photograph and then adjusting the curves endpoints for the respective color channels to bring the three channels into equality. Hmmm, a little hard to summarize, which is why tuning in is so helpful.
The other technique covered was the white background issue. Same deal, but this time using the builtin layer mask automatically generated on new curves adjustment layers. Makes perfect sense in retrospect! And produces much more pleasing results.
Well, I'm off to a meeting.

Light Photographic Workshops: Monday Night Lights
Last night, Monday, was the first of the Monday Night Lights (MNL) webinars that I have attended and it was well worth it ... well, yes, it was a free demo session, but I mean it was worth the effort to download and run the software which can be brutal for some applications and I won't put Silverlight on my system (it is a Microsoft product that apparently doesn't allow removal) which so many doing online classes want to use so I skip them. Anyway, GoToMeeting wasn't onerous at all and the software was flawless although it requires a little getting used to where things are, but no big deal.
The session was an introduction to PS "Curves", targeting mainly CS4 but with legacy discussion for previous versions, taught by Hal Schmitt, the soon to be legendary Digital Photography Instructor. Hal ran through most of the controls on the Curves Adjustment Panel using provided images (in case you wanted to do the exercises along with him.) He missed a couple on the bottom as we sorta ran out of time. But as always with Hal, he revealed two or three little tidbits that just wouldn't have occurred to me ... things as simple as dragging control points off the histogram to get rid of them, using the pencil, using the luminosity blending mode (which I should know but keep forgetting) when there is crossover coloring and a few others that I don't recall at the moment. This, of course, in addition to demonstrating the power of curves for adjusting contrast in images in RGB, explaining how the slope of the curve correlates to that contrast, how to use control points and how to mask when using the adjustments panel.
Normally, this hour long session, as part of a weekly series, would cost a whopping $5 (paid monthly ... ). What is it that you can get for $5/hour these days? And watch in the comfort of your own home while sipping on a gin and tonic and maybe a fancy chip or two? [I know Hal and Victoria would probably sip wine, but my wife hordes Hal's wine.]
So, a couple of other little items: MNL (this series) doesn't have an itinerary ... you can't really know what's coming! I thought this was bad. Now I see the added power ... if something really striking comes along there is no more than a week wait before Hal can share it. I mean there's a ton of stuff in the waiting queue, some of which I have requested, so it's not like there's nothing to talk about, but if there is a new update to Lightroom, new NIK filter, some cleverness with Imagenomic Portraiture or a hot new feature of Photomatix, it doesn't have to wait three months to get onto the end of the schedule!
Also, for those who prefer more structure in their lives, even in the online world, there is a schedule of more conventional webinars at LIGHT here. I'm considering Wednesday's Retouching People if I can get through some paying work tonight to clear the decks. I am hopeful that this schedule will be expanded significantly.
So, if you are feeling like you've lost the muse, are bored with your work, need to find some zippy energy by learning something new but don't have time to take a class or pore over a magazine article, then I'm suggesting MNL.

Light Photographic Workshops: Online Seminars
LIGHT Photographic Workshops (formerly Lepp Institute) has started a new service: Online Seminars. They seem to come in two flavors: specific topics with one time subscriptions and Monday Night LIGHTS (MNL) with unannounced topics. The MNL series is amazingly cheap: $5 a shot for once a week paid either monthly or annually. [Please note that you must verify all this information yourself ... I am only reporting what I believe to be the case.]
As an introduction to this service LIGHT occasionally offers "free" seminars and one of those is coming on next Monday night, June 8th. You can sign up at https://www1.gotomeeting.com/register/208559489 as well as find system requirements and time. My inside tip is that this seminar will be about curves for all you folks fearful of this adjustment.
Their website, after rebranding from Lepp to LIGHT is still available at http://www.leppphoto.com/index.html for more detailed information.
Hope to see you there!
