This tutorial is long overdue, and I'm horribly sorry about that! Well this tutorial is made for people who are interested in making similar photos found in this post (Multiple Exposure's Beauty). This tutorial is not limited to Adobe Photoshop CS2 and above - just make sure that your version of Adobe Photoshop allows you to change the Blending Options to "Screen" as well as allows you to alter the exposure of your photos (under Image > Adjustments).
This tutorial will be separated into 3 parts due to the slightly different skills used, but the concept behind it remains the same. Like what I've mentioned above, creating images of multiple exposure requires 2 main functions - altering the images' exposures and changing their blending options.
According to the Adobe Photoshop Help (which comes bundled along with the software itself), blending mode controls how pixels in the image are affected by a painting or editing tool. The blending mode we're using today is called "Screen", and it looks at each channel’s color information and multiplies the inverse of the blend and base colors. The result color is always a lighter color. Screening with black leaves the color unchanged. Screening with white produces white. The effect is similar to projecting multiple photographic slides on top of each other - this explains why we're using Screen because we're actually stacking images on top of each other!
Each part is quite simple, but I recommend you to get some coffee because there are 3 parts in total! Each part comes with their separate .psd demo files so that you can use it for reference 
hope you find them useful! Special thanks to Mediafire for hosting the files for me since FTP access over here is temporarily banned. The 3 parts are tucked under 3 different pages instead of under one single readmore tag because I just realised there are too many images to load! 
After concluding this post I realised that this is the longest tutorial I've ever posted! Hope you all find it useful! Here we go! You can either use the pages link below to navigate or just click the corresponding images:

haha! Anyways I love chocolate mint too! Maybe because of the mint 
it’s refreshing!
Grace: Thank you! Hope the tutorial is useful to you
yanni: I think the only major difference is the addition of better functions as we move from Adobe Photoshop CS to CS3. I don’t think they changed the user interface a lot, but I heard that CS3 has a lot more functionality than CS2. One of the major highlights, if not mistaken, is the improvement of Adobe Bridge and support for Raw Images, which both I don’t use
LOL!
