Learning - Scott KelbyTraining
One thing leads to another on the net and I somehow ended up at and found that for $200 a year, one could basically view as many 4 - 8 minute lessons as one cared to from around 20 instructors, includihttp://www.blogger.com/img/gl.link.gifng Scott himself, JP Caponigro, Don Margulis and a variety of others.
George Purvis had written me a while ago about the possible advantages of L.A.B. colour and recommended one of Don's books. Well, here I was on a site which offered video lectures on a variety of subjects including Don talking about L.A.B. Better yet, without even signing up you could try the first three lessons of any topic by any instructor for completely free - impressive.
I watched Don's first three lessons on L.A.B., enough to whet my appetite. I brought an image into L.A.B. via Image/Mode/LAB and tried an adjustment curve - wow - what power. Where in RGB one adjusts all the colours in creating a curve in the default setting, here you start out with L or lightness and can basically increase contrast without increasing saturation - an important tool. Better yet, you can flip in to A and B and use the same kind of contrast increasing S curve to separate colours further, without changing the overall balance of colours - somewhat akin to increasing saturation, but not quite.
In a matter of a few minutes I was able to dramatically improve a few different images, in what would have taken a lot more time back in RGB - hmmn, maybe this guy is onto something. No doubt you can overdo it but by using the opacity slider in the curves adjustment layer, you can tune it back and forth between zero and 100% opacity and choose what looks best - almost always less than 100% as it's hard not to go too far with such powerful controls.
Will this change my image editing, am I abandoning working with RGB for a life in LAB?
Certainly not any time soon - I might well buy his book, I may even break down and spend the $200 for a years subscription to ScottKelbyTraining, it's hard to believe I won't geet $200 worth of information out of these famous instructors.
A little more careful perusal of the site indicates they are just getting going and don't have a huge selection of lessons at this time - but I just purchased my first studio flash for some still life work and I see they have a studio lighting series - handy. Some of their listed authors don't even have lessons listed yet - eg. J.P. Caponigro. I guess this would make it a leap of faith that more will be coming and that by year end there will be plenty - but I think the concept is sound and the price fair and I don't see a reason for it not to fly.
Anyone have any experience with it yet - care to comment? Anyone who hasn't signed up, what do you think of the concept, the value, the practicality?
Getting back to the L.A.B. thing, the top image is after using LAB, the bottom before. I was able to warm up the sun, without yellowing the whole image and without needing masks, add a little punch without taking the colours over the top. I'm sure I could have done the same in RGB, but probably not nearly as quickly - there may be something to this LAB - I'll let you know as I work on real images whether it gains or fades.
