Well the great news is my design is a finalist in the final run; now it’s up for a public vote and I need your help in making mine the winner! What’s in it for me you ask? well unfortunately I’m just a poor graphic designer… I can’t offer monetary compensation – but you will have the satisfaction of knowing that you are part of why I won! That should be enough to hold you over with excellent karma for at least half a year! What a deal!

But in all seriousness: I put a lot of time and love into that design (even found a way to help others learn from it) and would really love to have it published and printed (nationwide too!).

I really appreciate it!

Instead, I decided on a stock image which seemed manageable to remove the background easily enough… Or so I thought at the time. My plan was to use the Pen Tool to create a Mask and remove it from the background. I realized quickly (well, actually not that quickly) that this particular item was way too complicated for the Pen Tool treatment.

Here's the Tree Stock Image I started with.

All I wanted was the tree; the sky and ground had to go, including the sky behind the tiny little branches. Now, because this was for a printed poster, the image is large, and has to be very detailed even when viewed close, so there wasn’t much room to fudge the details; I needed to remove the sky from behind each and every branch…

My first attempt was to use the Pen Tool and try to mask out the tree. But after 3 hours of work, this is all I had done…

This was just ridiculous, at this rate I would have been masking out this tree for 6-7 hours and been less-than-satisfied with the final result; because of this, I gave up immediately on this method (scratch 3 hours from my life… but better to save the rest than continue on with a poor method).

I ended up using Channels to do the task, and it turned out better than I thought it ever would!

How to use Channels in Photoshop:

I’m using Photoshop CS3 to explain this, but the method is very similar across the entire CS – CS5 tree (no pun intended).

Step One:

With an image (preferably the one you are trying to remove an object on) opened in Photoshop, choose Window – > Channels if it’s not already open. By default, the panel is tied in with the Layers panel.

Click on Window -> Channels to open Chennel Menu

Step Two:

Find which Channel gives the most contrast between the foreground and the background by clicking on each one Red, Green and Blue one at a time; the more contrast there is, the better your results. In my case, Blue turned out to have the most contrast.

Find the Channel which offers the most contrast

Step Three:

Using the Magic Wand Tool with a tolerance of 50 I clicked on the tree. The tolerance settings may need to be adjusted depending on your image, however this worked well for me. It did though also pick up the ground:

I simply used the Rectangle Marquee Tool to unselect the ground, leaving the tree the only selected object.

Step Four:

Head over to the Layers Panel by Clicking on Window -> Layers. You will see the image has returned to full color, yet the tree is still selected. Then it’s just a quick click of the Mask icon in the Layers Panel.

Click on Layers Panel and your object, in full-color is now selected.

Click the Mask Icon and watch the background disappear

That’s it! 5 minutes of work beats hours and hours every time!

I was then able to use the tree in my final composition, and the space between branches showed the design elements behind it!

I started by taking all the images I had taken, and used Photoshop to photo-merge them into a single panorama; the graf art is very wide.

[TIP] To Photo Merge many files into one, with all the files open inside Photoshop, click File -> Automate -> Photomerge and choose the type of layout, then click “Add open files” … The box will populate with the filenames of all open documents -> Click OK

I have the finished piece available in 300 dpi JPG image at 11,629 x 1,707 pixels, and the rest available in 3 separate sections in 2,500 pix wide, 300 dpi PNG files with transparent backgrounds.

I decided to give away the full-resolution image as a Stock Photo for you to use.
