CIOS152-Lesson 3

Another rich chapter with lessons that I enjoyed doing...
It has been a long time since I learned about hue and saturation so it was good to refresh my memory about them...
The tint is the core color like a rainbow and saturation measures the intensity of the color.
I love being able to change the color cast using the Variations command under the Adjustment menu. I like that under the midtones option it shows us all the different variations with the filters of more green, more yellow, more cyan, more red, more blue, and more magenta and then to top it off it shows the current pick, lighter pick and dark pick all the same screen!!! that just amazes me-it is quite convenient to have the choice of having a fine or coarse intensity level with the fine/course slider bar. Variations changes brightness levels-highlights, shadows, and midtones.
Coloring the grayscale image was very interesting, I thought the photo looked fine as it was so it was very cool to be able to use photoshop to "color" a photo. The important thing for me to remember is to add channels and to do so one must choose Image, mode, RGB Color and then to turn on the Channels palette and walaa I'll see the Gray channel turn into Red, Green, and Blue plus the RGB composite and because this allows us to add channels it allows us to colors...The Hue/Saturation command allows us to turn on the Colorize check box which applies the Hue and Saturation as absolute colors and it is at this point that we enter a Hue value which creates the color! The Gradient Map command substitutes the luminosity values with the colors in the gradient! and if that was not enough it allows us to choose from a menu of Gradient menus that allow all kinds of cool colors to manipulate the photos with-the artsy kind of stuffs....fun fun fun!
Camera Raw
The other method for correcting or changing colors deserves a title just because it is way cool-it can edit multiple photos at once even! According to the book, it represents the unprocessed data captured by thy camera's image sensor. It has more flexibility because it is larger and contains more info and captures a wider range of colors...within it one can change things like White Baland to neutralize a color cast, change Temperature value to compensate for the color of the light source!Tint even lets you adjust colors even more along a color axis! The really amazing thing is that while in this program one does not permanently while in Camera Raw! so not only does it do all these amazing things, one can adjust highlights, shadows, and midtones-just like a real darkroom! The Vibrance and Saturation command changes the skin tone color when the exposure is not so great-I love this program! At first I was a little dubious about it but it is quite a handy program!
The Tone Curve command can get pretty detailed in its correcting abilities as well, the lesson he had us to do showcased how good that program is because of how he was able to do all the little changes that made a big difference!
Wow, switching into the HSL/Grayscale panel was fun because of how we were able to choose the Hue of the flowers right before our eyes-I had alot of fun with this as I exaggerated the colors and again it was artsy! I can see why people who have Adobe can get locked into it and not want to quit using it!
I loved the ability of the program to "heal" photos and get rid of blemishes relatively simple and clean...
The lesson pertaining to changing the color photo to black and white came in a close second as I love black and white photography and the Split toning was way cool and all it took was switching the channel mixer t monochrome....
Again, I learned alot in this lesson and the bonus is that it is fun-only hope I can retain some of the lessons!
