lj_1999 Posted October 12, 2005 Share Posted October 12, 2005 Hi all, it's so nice to meet so many experts here. I am working on a project and get stucked, wish you can be kindly can help me out. Maybe it's not the right place to post here but ... PLS see attached photos, I want to replace the grey pole in photo Whiskey.jpg with the Pine Tree, and match pine tree's color with scene. I tried use photoshop 7 to remove the background (all the white color) of the Pine Tree ,and merge this tree to photo Whiskey. The problem is it's hard to get rid of all the white color because of the tree branches; and after i paste the tree to the other photo, the color doesn't match that good. Anybody can show me how to do it right? Greatly appreciate it. Lucy Link to comment Share on other sites More sharing options...
Sketchrender Posted October 12, 2005 Share Posted October 12, 2005 In Photoshop. copy your image on to another layer. select the new layer, go to adjust contrast and brightness, play with the levels untill the colours are black and white, and then use the select too, adjust the setting on that if you need to, and then invert the selection , and copy and paste in to the other pict. By the way the pine image is not very good, you should think about using a different render. phil Link to comment Share on other sites More sharing options...
edub Posted October 12, 2005 Share Posted October 12, 2005 By the way the pine image is not very good, you should think about using a different render. phil that's not a REAL tree! it a cell phone tower, disguised to look like a tree. My guess is that you want to show how the "fake" tree tower looks, in place of the "real" tower? The technique described above will work, but your "fake" tree is not the same perspective as the "real" tower. This is your main problem. You need a view from below, and not a dead-on elevation. You might be able to fake it in p-shop by stretching and distorting the image, but since you're, seemingly, a p-shop novice you'll have a tough time.

1eo Posted October 12, 2005 Share Posted October 12, 2005 By the way the pine image is not very good, you should think about using a different render. I second that....

lj_1999 Posted October 12, 2005 Author Share Posted October 12, 2005 acturally, my client wants to build a fake pine tree tower, and need a rendering similar like that. Leo, yours are great! it helps me a lot. How did you extract the tree from the original background? any trick? I tried but still has some white things left:( If you can explain this to me, I would appreciate it very much. Link to comment Share on other sites More sharing options...
1eo Posted October 12, 2005 Share Posted October 12, 2005 when I get home from work and from my TKD classes I'll be able to help you more.... What is wrong with yours? looks too fake? if that's the case maybe you need a better tree. Please let me know what "exactly" needs improvement so I can help you when I get home leo Link to comment Share on other sites More sharing options...
William Alexander Posted October 12, 2005 Share Posted October 12, 2005 If you rendered the tree tower....save it with an aplha mask, like tga format. Use the aplha channel to mask your tree in the composite image. For what it's worth..... I used the blue channel to make the mask for the tree...then dropped that layer into the wiskey image. Used the perspective transform, cloned. Put the new layer into a set (passthough to normal) and did a levels layer to darken the tree tower image and adjusted the green levels to take the vivd bright green away. Then a Hue Saturation adjustment layer to lower the saturation and a hue shift to make it fit better tot he whiskey image. WDA Link to comment Share on other sites More sharing options...
lj_1999 Posted October 13, 2005 Author Share Posted October 13, 2005 I am really a photoshop novice! tried to follow all your procedure, but still couldn't get it. What I want is extract that fake pine tree and merge to the other photo and get the result like what Leo and WDA did. I have problem with extract the tree from its background. WDA explained very detail, but i couldn't get it. After I droped the blue channel with tree mask to the new image, I got a new Alpha 1 channel, I could do the perspective transform, but what to do with "cloned" and how to "Put the new layer into a set"? If you can get a couple a screen shot, I would appreciate it. Thanks. Link to comment Share on other sites More sharing options...
1eo Posted October 13, 2005 Share Posted October 13, 2005 I didn't even bother to try masking anything... look carefully at my first screen shot. I selected the "tree" layer (layer 2 in my case) and played with the layer properties. In my job's flat screen looked pretty good... however once I got home and look at it in my monitor I realize how bad of a job I did Link to comment Share on other sites More sharing options...
1eo Posted October 13, 2005 Share Posted October 13, 2005 If you really want to learn how to become better at masking... then You're gonna have to learn how to use the alpha channel First look up what alpha channel do... (I have no time to explain it... my break is too short) then look at my pics 1. copy your tree layer, and make it b&w = (ctrl + u , sturation -100) 2. crtl + I (invert) and make sure everything that supost to be 100% solid is white (Refer to your own reserch of what alpha channel do) 3. go to "channel" and create a new layer (red arrows) 4. copy and paste your "B&w inverted layer" 5. comeback to layers, erase the "B&w inverted layer", select your regular tree layer, then go to = select , load selction and choose alpha 1. from then on just drag your tree to the background that you want Regards, Leo Link to comment Share on other sites More sharing options...
lj_1999 Posted October 13, 2005 Author Share Posted October 13, 2005 You did a great job, Leo! thanks a lot:) Now I found it out you had changed the layer Properties to "Darken", that's was the key! Good to know about this. I didn't even bother to try masking anything... look carefully at my first screen shot. I selected the "tree" layer (layer 2 in my case) and played with the layer properties.

William Alexander Posted October 13, 2005 Share Posted October 13, 2005 Great Job Leo Lucy The channels are your friend, even though they seem evil now LOL. There are many methods for pulling a mask from an image and a whole lot more, with a great deal of adjustable control. This is an area you may desire to put some time into learning...very well. many sites with PS tutorials...one of the better ones, historically to understanding compositng is http://www.dvgarage.com/ look into the free tutorials-compositing. Another learning site, lots of information about alpha channels, they rule the world... www.pixelcorps.com, a couple free tutorials. You need to create an account to see the goods, though, on both. The second one may be worth checking into a membership. WDA Link to comment Share on other sites More sharing options...
lj_1999 Posted October 14, 2005 Author Share Posted October 14, 2005 Thanks, WDA. I have found a photoshop book and start further learning... The two site you recommended are very good and helpful, thanks for sharing. Link to comment Share on other sites More sharing options...
