    I entered one of the PP challenges recently and damn me I won.... anyway my winning entry was an experiment by myself in learning a bit more about curves, and in particular using multiple curves with masks.

    As I had some time this afternoon, I sat down and did a little video showing the steps I went through, and thought it might be of some use

    All acknowledgements to Robbie36 for the image, and to ScreenFlow for the screen capture. I didn't record a voice over, just subtitles so it is silent !!

    Very insightful. Thank you

    Just one question, I didn't quite get it how did you selected the door or the wall, you had the masks pre-made right?

    thank you

    yes I had the masks pre painted for this video... it was just a quick project to show the idea of having multiple curves, and how adjusting the RGB separately leads to some useful effects

    cheers

    Great vid Kevin. I am a Mac/LR user... I have never used Aperture, but I have always been told they are mostly the same w/ LR having a bit more options, but as far as I know, multiple masks and curves are not possible in LR.

    to me, that was an eye-opener. Never gotten the hang of curves, only stuck to levels... this made sense though, so I´ll be trying it out:)

    Multiple masks, yes. LR now has several selection tools: radial, brush, etc. However, the adjustments possible of the mask are fairly limited and don't include curves.

    Very interesting video. Thanks, Kevin.

    thanks for the comments

    the masking and the multiple adjustments in Aperture is underappreciated in my opinion. Its not perfect by any manner... you cant copy a mask from one adjustment to another, though there is an applescript that seems to do it

    I havent tried it.... but i probably should

    any thoughts/feedback on the style/format of the video.... too long...too short... does it need voice over?

    cheers

    K,
    Thank you very much for sharing this technique, which I was totally unaware of. I really appreciate the time and effort you spend for creating this insightful video.
    Kind regards

    This is a fantastic tutorial and, while I'm at, it's a super shot that you used to do the demo.
    Really love Rob's shot here. Think I missed it but could you link to the final shot from the challenge that you won?

    LR doesn't have this level of customization. I think that this is actually a lot more powerful than what Lightroom offers with the selective adjustments. In lightroom I tend to jump into Viveza if I want to accomplish the same thing as you have with the masks here. I do have a photoshop licence and have it installed but my photoshop skills are crap and to be honest I find it quite intimidating.
    I find Nik plugins much easier to get around and get better results because I'm more comfortable there.

    Can you do selective sharpening / noise reduction as well from Apperture?!

    Yes, the only adjustments I can think of that can't be brushed in and out are "RAW Fine Tuning" and "Exposure". You can also create multiple instances of almost pane except those two, "White Balance" and a few others.

    That being said the Noise and Sharpen panes are kind of minimalistic and could really use an upgrade.
