  • Complicated selection

    As can be seen from the attached (which is a cropped section of an 1897-era US Navy Cruiser rigged for both sail & steam), I am having quite a time attempting to separate the ship from the background, which is mostly sky, yet preserving as much as possible the intricate rope rigging (and is there ever plenty of that!). Up to now I've been using the Magic Wand tool with a fairly low tolerance but I wonder if there was a better way to have started this in the first place. The spaces needing to be cleared are getting smaller and tighter, and I still want to avoid wiping out stuff that should stay in the picture. Perhaps a mask of some sort? I know there are quite a lot more than just the ordinary layer variety. This is a LOC photo, and is an 8-bit grayscale. If I'm missing something that should be obvious, please feel free to point it out; that's why I joined this group, to learn how to do restoration the right way. Thanks!

    The mask is already there (probably) in the channels and by manipulating one of the channels by adjusting levels or curves to gain a black and white image you will be well on the way to separating the detail your require.

    Usually finding the mask in the channels will give a better result (more precision) than using any of the selection tools

      If it's on a white background, or near white, you can adjust the levels as Tony said and use multiply mode to move it and its water to a new background. The neutral color for multiply is white.

        My thanks to both of you, and I'll be having another go at this taking into account what you've suggested. Since this is grayscale, there's only one channel, but I'll proceed with it and make a channel mask using levels (or curves?) to boost the contrast to stark black & white. I'll be working as time permits, but hope to have something to show soon.

          The channel mask is what I ended up going with. The background of the original might have been white but after 117 years it was dirty gray, at least 3 distinct shades of it, too. It was also a grayscale image, so only had one channel to work with. After I copied it, it was image > adjustment > threshold to start, and used a hard brush in black and white as needed until I had a good silhouette and a stark white sky. I loaded it as a selection, cleaned that up, went back to layers and hit the Mask button. There's still a ton of work to do on this, but isolating that rigging was what had me treed for awhile. Thanks to all who gave advice. I've attached a WIP shot of the mask under construction, and one showing the mask applied; since it's just a .jpeg screencap, the background is plain white (which shows that rigging to good effect, though). I've got the original saved as a .Tif with the mask and the background is for now transparent.

              Good job, pleased to see that it worked out for you. A little interest to the sky may be your next move and should lift the image

                hey all..I am trying to do something with a photo, and I figured turning the picture itself into a mask would be eaier.

                I've tried several different ways to do it. I've looked for help all over the place, but I can't seem to find directions easy enough to follow.

                I know...

                Trying to create mask
                by RamonaMarie
                I know I'm just a beginner, but I think of myself as highly evolved and able to follow directions. I've been watching and reading several masking tutorials all day and can't get this little guy (now 58) fully selected so I can change the damaged background. This photo was pasted down in an album and...

                Mask around trees
                by NWPhotoGuy
                I hope you'll give a newbie a little assistance.
                I'm faced with a number of pictures where I want to mask the sky but the line of demarcation is filled with fir trees. The magic wand masks most of the sky but there is always the bits within and among the trees that is not masked. Is there a way...

                Hi, I like to use both Photoshop 6 and Corel Photo Paint for colouring black and white images. However I prefer to use Corel Photo Paint as there is a handy little tool just called a brush, it is found on the tools palate along with all the other selection tools. you can push the pixels into the outer...
