    Hi,

    Here is the procedure to do focus stacking with CS3. Its a more manual process versus CS 4 however Im not paying $1800 for the CS4 package….yikes. OK here I have 3 images of a shelf full of books. The first image has the focus on the 1st book, the second image focus on the middle set of the books and the last image focused on the last 4 books.

    Next step is to load the 3 files into CS3 in order of the foreground sharp, mid ground sharp and background sharp

    Next you need to align the layers. Select all the layers by clicking on 1st layer and then "shift" left click on the 2nd and 3rd layers. They all should be highlighted as in the layers dashboard on the right of Picture 4.

    OK once this is complete…you are ready to add the layer masks

    Now its time to add the layer mask on the top and middle layer. Select the top layer via the dashboard on the right. You can only do this 1 layer at a time

    Repeat this step of adding a layer mask for the the middle layer

    Now once you have added the layer mask on the top 2 layers, you are now ready to erase the top unfocussed layer to reveal the sharper focussed areas below.

    1. Select the top layer mask icon as shown in picture 7…the small white blank rectangle
    2. Select the Eraser Tool E from the tool list on the left
    3. Adjust the eraser diameter accordingly…not too big not too small with a soft edge
    4. Now start erasing the blurred section on the image, you will start to see a sharper image reveal itself after you erased the blurred section
    5. Continue the same process with the middle layer by selecting the middle layer mask.
    6. Areas that you have erased will show up as black areas in the layer mask icon.
    7. Once you complete revealing all the in focus areas…..merge the layers and flatten the image.
    8. Walla…….great DOF image as shown in Pic 9.

    Thanks Dennis for posting this. CS4 is much easier. ;) If you have school going kids at home, get an educational copy, it is only S$99 and you have the full suite (including PDF writer, dreamweaver, illustrator, etc). Who said kids are liability?? :D

    Cheers,
    SC
