Mask is a tradition in PS, but in CS4 there is a new mask panel, which let you quickly create a pixel mask (I did not explore vector mask yet) from selection or color selection. Mask in CS4 can also be added to an adjustment layer, which is also new in CS4.
Mask is generally for making a selection f
or an effect. Mask can make an effect on an image localized. The mos
t common mask we see in PS is in a solid shape. The shape is actually a shaped mask on a solid color.
By utilizing mask, I made different adjustments to a statue and its blue sky background. Eventually I made the stone statue into a golden one and made the sky a little yellowish in order to correspond to the statue.
After I mastered the different utilities of mask I'll try to make a whole summation.
What I also learned is another utility of Smart Object.
Smart Object is a new feature in Photoshop CS4. By converting a layer to a SO, PS makes a copy of the layer and saves it with the SO. As a result I can add non-destructive, re-adjustable filters to the SO.
Furthermore, The duplications of a smart object have one same source. So that by editing the source file, which comes into being after a double-click on the SO, I actually altered all the duplicated files simultaneously.
Later I tried out adobe contribute. I think I'll expand on that later
Okay, That's it for today.
P.S. I also learned that placing photos is not so user-friendly here
