There is really no correct shutter speed, but it will often change the look of your photo. For example, do you hope to stop action (fast shutter speed), or have a blurry effect of motion (slow shutter speed). If you are holding your camera rather than having it on a tripod, a fast shutter speed can help minimize the effects of camera shake that will cause an out of focus, or blurry look.
With my camera in Manual mode I can choose a shutter speed I want, then find the matching f/stop that brings the exposure reading to 0.0. Or, I can set the f/stop and change the shutter speed until the exposure reading goes to 0.0. Then I review the images and see if I have gotten the results I want.
You can also change the results by changing the exposure number, too. You can go darker or lighter than the 0.0 exposure. This method is referred to as "Exposure Bracketing".

You can also take his course online under the same title as his book, and Learning to See or "the Art of Seeing". You will be given an assignment for the week, submit photos and receive critiques. I am presently in the middle of week 4 and have learned a lot. (Art of Seeing) Bryan also includes some short videos giving fun tips for photos.

MWAC: "Values: a set of consistent ethic values (personal or cultural) that measures the purpose of integrity and moral code."
Is it accurate to say that many religious people and many non-believers share these same "values", but the main difference is that religious people believe we get these values from God, they came from God, and others believe we create them by ourselves. Each of us is capable of creating our own set of values. Others say no, these values come from a higher source, not man. We cannot just create whatever values we want to go by, we need to look to a higher spiritual source.
Did God create man or did man create God?
Let's not discuss or judge people. Let's discuss or debate ideas.
Check with how the remote works with your camera. With model Olympus e-620, the wireless has to be out front. The wired version works great, but is more cumbersome and tends to falls out when moving the camera, if not carful. I already lost one.
From Scott Kelby on tricky hair selection:
Using a head and shoulder shot of a lady with some wavy strands:
Use the Quick selection toll over the entire image, work carefully to include the strands, but you do not have to be exact with it. It helps to enlarge the image as you select.
Goto the Refine Edge button up in the options bar.
In view mode, choose the Black and White.
You will see how well you did with the jagged edges, and why 'refine' is needed.
Turn on (check) the Smart Radius box.
Drag the slider right, watch the hair. You should see some detail appear.
Goto the Overlay View. The hair parts that did not get selected should show up as white areas.
Gotto the Refine edge tool (That is the brush icon to the left of View).
Just paint over the white areas That's it! You have selected out the difficult strands...the fine hair details.
Down at the output section click on Decontaminate Colors. This removes color spill over. It desaturates the edge pixels.
Choose New Layer with Mask.
NB: No need to get involved with the Adjust Edge section.
Thanks to Scott Kelby's Book on CS5. pp.256-259
He goes on to show how you add the new background.
No! Wait! Hair selection is made a lot easier using REFINE EDGE!
1 Make a loose selection with a lasso tool.
Now Under SELECTION>Refine Edge
Study all the options in the refine edge panel. Amazing, it make hair selection easy!!
Start by clicking the arrow next to the box with the picture. Check out all those different views.
Next learn about all those different slider options!!!!
Move the slider under "Refine edge" See what happens?
Refine even further, click on that Brush Icon just to the left of the Refine Edge box. Paint to add or paint to erase.
Keep going with the rest ......
PART II
Another way to make easy selections using Quick Mask.
1 Use any tool to do a quick selection around the object you want to select.
2 Click the button at the bottom of the tools panel or press Q.
3 You should have a red overlay over everything, but the selcetion
4 Paint in the areas you missed (Deselect from your selection by using black) (Extend the area of your selection by painting white)
Create a soft edge by painting in gray (use the opacity %, too)
You can change the color of the mask by double-clicking on the Qick Mask icon.
5 When you finish fine-tuning press Q and the marching ants should re-appear.
NOTE: When you double click on the Quick Mask Icon, notice you have a choice of Masked Area or Selected area as well as a color choice. If you choose Masked Area, the area that will be covered in color is the area NOT part of your selection. Therefore, you will be painting to disclose what you want to be included in your final selection. If you choose Selected area, the color will be covering the area within your selection. You will then paint over areas you want included.
Use the black and white brush selection, switch between black and white foregrounds, to either add or erase.
Also, note the the brush Mode should be "Normal".
Use how to use the Adjustment Brush in Camera Raw It is the 10th icon over on the tool bar at the top of the page. This will do lightening and darkening much like a layer mask can do in PS.
Use Layer masks, quick masks and as you refer to, Channels or editing Alpha Channels.
Here is a walk through right out of the Missing Manual, p. 205.
download the Balloons.jpg found at missingmanuals.com/cds. Save it in Downloads then open it from there into PS.
1 Open the Channels Panel (Select Channels under Windows, if not already open)
2 Open the darkest channel, in this case the blue one, then duplicate it and label it "Blue Copy"
3 Choose Image> > Adjustment> levels (Open an adjustment layer and use levels)
4 Move the black slider left until thew balloons are almost black
5 Use the white eyedropper (the third one in the row in the Levels box) and click on all the gray areas until all of the sky is white
6 Paint the balloons light spots with a black brush to get them all black. (Switch between the foreground black to add black and the foreground white to erase if you blacken too much)
You now have black balloons and white sky.
7 EASY SELECTION STEP!!
"In the Channel's panel load the duplicate blue channel as a selection by Command-click Mac or ctrl-click on PC, or clicking the 'Load Channel as selection" button (the dotted circle at the bottom of the panel." p.208
Check out those marching ants, the selection has ben done for you!
8 Invert the selection to select the balloons instead of the background. Command shift I on Mac or ctrl,shift,I on PC
9 In the channels panel turn on the composite (RGB) channel and HIDE the duplicate Blue Channel
10 Open the Layers panel, (make the background layer editable by clicking on it) and then add a layer mask (hit the circle-in-the-square button)
Done.
Now you can copy and paste a new background (eg. Blue SKy with Clouds) drag it to the bottom of the layers stack to put the balloons on top of it.
Okay,try this one: Store and catalog your images in lighttroom, process them in CS5.
Photoshop CS5 The Missing Manual. by Lesa Snider Very helpul. Here is an example:
goto missing manuals.com/cds and download the practice file Balloons.jpg
(save the image to Downloads and open it into PS from there) This is a good image to practice on for changing the sky. The Missing Manual will lead you through a step-by-step process using the Color Channels and layers masks.
Learning to work with layers and masks is very important.
Look in to joining Kelby Training for year round access to many video lesson on photography and Photoshop. Highly recommended Scott Kelby's books, too.
Kelby Training already has video lessons on LR 4.

I took a four week class online at BetterPhoto.com, "Basic Masks in Photoshop" with Doug Steakley. He helped is work on our own photos.
Do not overlook free help from Adobe:
http://www.adobe.com/support/photoshop/gettingstarted/I also followed links others gave at this website to find this:

Whoops, the above refers to you "Preview Button" to view DOF.
Your Field of View should show you the difference between looking through the view finder and what you see in the LCD. For example, when I look through the viewfinder on my camera, I do not see a lot of the sky, or what ever is in the top of the scene that appears in the LCD and in the final picture.
