1.  Your camera tells you that 1/125 @ F11 is the correct exposure.  List two other exposures that would allow you to bracket around this reading.    1/125 @F16, 1/125 @ F8

2.  Fill in the intermittent apertures.

    F2  F2.8  F4  F5.6  F8  F11  F16 F22 F32

3.  Fill in the intermittent shutter speeds.

   1sec  1/2sec  1/4sec 1/8sec 1/15sec 1/30sec 1/60sec 1/125sec 1/250sec 1/500sec 1/1000 sec

4.  F22 would produce a shallower depth of field than F8.  True  

5.  While photographing a scene, the camera shows that 1/250 @ F16 will produce a correct exposure.  Give two equivalent exposures for this reading.  1/125 @ F22, 1/500 @ F11

6.  Which shutter speed would best stop a car moving across the frame.  A) 1/1000 sec  B) 1/30 sec     C) 1/4000 sec  D)  1/60 sec 

7.  Dodging is the global adjustment that will darken areas of your image.  False

8.An ISO rating of 400 is more sensitive to light than 800.    False

9.  What is the difference between global and local adjustments?  Global adjustments apply to the entire image, while local adjustments are for specific layers only.

10.  How many mega pixels you need to make a 8x12 print at 360 ppi?  12 megapixels

11.  Name two tools in Photoshop you can use to adjust the density (brightness) of your image.  levels, dodge

12.  Name three tools you can use in Photoshop to change the color of your image. Color replacement tool, paint bucket, selective color layer adjustment tool

13.  What is the best file type to use when emailing or posting pictures to the web? .JPG

14.  What is the advantage of using adjustment layers?  By using adjustment layers, you can edit the image in a different layer instead of directly changing the original pixels of the image and therefore keep the original intact.

15.  What color workspace is best used when editing photographs?  RGB is the best color setting to work with when editing images digitally.

16.  A histogram is a graphic representation of your image and can also be used to judge for correct exposure.

17.  Name two tools in Camera Raw you can use to change the density of your image.  Tone Curve,  Sharpening

18. Name two tools in Camera Raw you can use to change the color of your image.  Temperature adjustment, tint adjustment

19.  What is exposing to the right and what is its advantage. Exposing to the right is shooting photos over exposed and then darkening them in post processing.

20.  Draw a basic histogram for an underexposed image.

21.  Draw a basic histogram for an overexposed image.

22.  Draw a basic histogram for a correctly exposed image.

23.  What is the best file to use as a layered working file in Photoshop?  Working with a PSD file is best for layers in Photoshop

24.  Name two advantages of having a larger digital sensor.  Higher resolution, better performance in low-light

25.  Pixels of unrelated color and/or brightness to surrounding pixels are known as noise

26.  Name two factors that would cause noise. Sharpening an image in photoshop too much, expanding an image without converting it to smart object

27.  In camera raw what is the difference between the Vibrance controls and the Saturation controls. The saturation control affects every pixel and even changes the colors, while vibrance just increases the vividness of the colors.

28.  Images made of pixels are known as vector based images.  False

29.  Name two tools you can use to retouch a photograph.  Healing tool, masking

30.  Name three tools you can use to make a selection.  Magic wand, direct selection, Marquee Tool

31.  Name two tools in Camera Raw can you use to adjust a particular area of an image.  Shadows, Highlights

32.  When editing an image what does the term “clipping” mean.  i.e. highlight clipping.

Clipping can occur when an image is over exposed the light pixels all turn white and have no depth, also in an under exposed image the dark pixels can turn black and have no information in them.

33.  Name two advantages to shooting with a raw file.  Larger image with a higher resolution, jpg format messes with the file and changes the colors when it flattens it

34.  What software is best used to get the images from your camera onto your computer?  Adobe Bridge

35.  What is the best way to erase areas in an image? Use the mask tool so that you don’t damage the original image and can undo it

36.  Name two controls in Camera Raw used to recover image detail.  Exposure, Clarity

Bonus  +1 each

1.What year was the first digital camera produced? 1975

2.What is the temperature scale used to measure color temperature in photography?  Kelvin

3.What president is on the $100 bill? Benjamin Franklin is on the $100 bill, but he wasn’t a president
