    Lightbulb Colour select

    I am using an image that has a very distinctive area of blue sky... that I want to get rid of.

    I have vanished the bulk of it using maskmode, but have a thin line left around the edge.

    How do I use a color mask to select the blue bits and delete them: I have done so to the majority, but I really want it to either select pixles or not select them - at the mo it does a 'under50%' selection thingy.


    Any better options?

    This is the image BTW: w ww.walford.ca/hiking/coyote_buttes/DSC05789 (Dot) JPG
    (Rather big so dial-up beware! And the (dot and spaces are a get around for the anti-link-5 post spam thing - thought it was better than just spamming 5 threads? )

    Thanks, friends!

    go to select colour range and make a selection of of the blue sky should be quite accurate then add a hue saturation adjustment layer and you can colour the sky however you like or brighten \ darken it

    The issie is, it isnt that accurate - I am left with either blue pixles or end up killing soe of the ground.

    Can I use the color select tool within , and only within, the bounds of a current selection?

    , don't know if you have gotten ananswer you like yet. Sometimes there is no complete shortcut in Photoshop. If I were doing this, I would use the quick select tool (if you don't have it, use the wand though it isn't as good IMHO for the task). Zoom in and clean up the selection a lot but don't spend tons of time on it. Create your selection and go into refine edges; alternately create a mask then go into refine mask. In either case you want to move the edge down into the mountains. One thing about organic images like this is that they are forgiving about changing the edges some. I made a selection of the sky, did selection>refine edge, added 14 pixels, no feather, no smoothing, 8? for contrast. This brought the selection into the ground, but made a fairly clean mask. Even then it needed a hard brush (because it is rock) on the mask to remove the slight blue halo. You might get cleaner results with a higher number of pixels but I didn't want to blunt the edges too much without seeing them.

    Re: Colour select

    that's odd because I just switched to dark theme and I can see the whole img on my screen, but is that just because it is my screen?

    Re: Colour select

    it is not your image I was referring to that is fine it is the fact you have black text so I assume you chose black as your colour let me guess it was blue from the link you embedded and you switched it back to black via the colour pallet
