Using lab colour........

Got a thin skin? Then look elsewhere. Post a link to an image that you've made, and invite others to offer their critiques. Honesty is encouraged, but please be positive in your constructive criticism. Flaming and just plain nastiness will not be tolerated. Please note that this is not an area for you to showcase your images, nor is this a place for you to show-off where you have been. This is an area for you to post images so that you may share with us a technique that you have mastered, or are trying to master. Typically, no more than about four images should be posted in any one post or thread, and the maximum size of any side of any image should not exceed 950 px.

had a play using curves and lab color on a old pix......I thought the first one was good till I had a play using curves, A and B channel in lab color. Just makes the colors jump......... more testing to be done on other images.......

image 1 using rgb color

Image 2 with adjustments using LAB color and returning to RGB. This is my first test using LAB color and more testing needs to be done, but I think you will get much better color using LAB color and a profiled monitor

I prefer version 1. It has nice, silk tones. Second one if oversaturated and it really doesnt matter if you do in in saturation slider or playing with channel a and b ;-)

Give #1 small bump and that all, will be perfect.

Regards,

K.Polak PS Also in #2 you introduced banding. That is definitelly not good.

Lab color is an interesting mode, I play around with it all the time. Adjusting contrast in each channel will give you a similar result that you got with the curves.

For some reason I like the rainbow effect of #2, yellow->orange->red->green->blue.

Looks neat :)

Doing a bit more testing and research, LAB Color does tend to be a bit on the red side which you can ajust to suite your image, I have improved the pix I have posted but yet to add to this thread as i am still doing some research, but with Photoshop there is more than one way to do things, and you find the one that will give you the results that you want......

That's a great tip, I'm amazed at how many ways there are in PS to do similar things just with greater subtle controls... I'll have a play with that later, thanks.
