By reading deviantart, i found a tutorial on how to simulate infrared filter on an image. Among some techniques I read on the net, I saw this one should be the best one. So I write it here for you:

• Open an image. As mentioned above, I use one from shareapic.net.
• Give a new adjustment layer: Channel Mixer with following adjustments:
  

  Don’t forget to check Monochrome checkbox.

• Change blending mode to Screen and adjust it’s opacity, like this:
• Again, add an adjustment layer: Channel Mixer. Leave Monochrome box unchecked. Adjust the Blue slider to the lowest value (-200%).
  Adjust the green slider until you get best looking tone.
  

  

• Then create new empty layer. Bring it onto the top of other layers, and press CTRL+ALT+SHIFT+E. This will merge all visible layers into the top most empty layer.
• Apply Gaussian Blur to this layer:
  
• Change it’s blending mode to Linear Burn and adjust opacity of this layer until you get best look.

Here my sample of this technique, both before and after:

Hope this tecnique usefull for you

You should ever seen PS CS3′ Splash Screen, which colored in blue and some texts in white. When running, PS CS3 displays this splash screen with some animated text informing progress of components those are being loaded. Or in About box, you see legal notice text and some patent information displayed there, on the same background.

I did. And I thought a way to change this splash with my own. After a couple of days, I did it, with my hand made software CS3 Splash Updater.

Below is my sample splash screen used to be a sample for this software:

If you’re interested, here is the download of the software:
CS3 Splash Updater Download – 218KB
You must change extension of the downloaded file from PPT to ZIP in order to open it!

To use, just run it, click browse to obtain Photoshop CS3 executable’s path, and then click Get Splash. The splas screen will be saved as a PNG file and you can edit it. Afterall, click browse again to get CS3 executable again (if you didn’t close CS3 Splash Updater during editing the splash screen, you needn’t to do this). Then click Update Splash to select the edited splash file (must be PNG!). If you do everything well, a success message will appear.

I have a technique for doing this, and I have been using it since 2005. That year, I work for photograph studio in Makassar, Indonesia,
found that the most of photographs’ background must be changed into landscapes, abstracts, or others. By reading on internet, I knew best way
to do this was by using white screen (we used thick white paper) as studio background, and gave enough light to obtain really white screen.

When imported and edited within Photoshop, I used “multiply technique” – I don’t know how has named it, but it really uses multiply blending to work.

Let’s see how it works:
1. Open an image – portraits should give better result.

2. Retune colors until the background become white and skintone become natural.

3. Double click layer Background (it should be the only layer). Name it object, click OK.

4. Right click the layer “object” and duplicate it. Now we have two layers, “object” and “object copy”.

5. Change the lower layer, the “object” layer’s blending mode to Multiply.

6. Add a picture and make it the bottom-most layer, which will be the new background.
7. Select the top-most layer and apply layer mask to this layer.

8. We can now start to erase the background of the top-most layer (in masking mode). Don’t erase white object other than background.
9. See detailed at red-marked parts. We can use layer-mask, black forecolor and white backcolor, then use brush tool to paint around the hair.

10. As you can see, this method works perfectly

For your notice, this technique works good on white down to light-gray canvas, but not various-colored canvas. Other time, we will discuss other techniques
for other cases. Keep reading
