This week we are experimenting with Light writing and Light Painting in class. You are required to participate, create and invent ways to make a long exposure photograph. We will also take digital underwater still life photographs, and learn to edit them in Photoshop.
A total of 6 photos are due this quarter! Here are my due dates, handing them in early earns a reward of 10 points on the grade for the photo;They can be digital OR film prints, but you are still responsible for the digital information and vocabulary.
> 1 is due this Friday May 5 > 1 is due fri May 12 > 1 is due fri May 19 > the last 3 must be turned in by May 26
> After that we review for the final exam on June 5th
> There are three Quizes coming, for the next 3 Mondays; May 8, 15, and 22nd. The quiz on the 15th include the vocabulary below:
Vocabulary to Know: see http://www.photoshoplab.com/photoshop-tool-basics.html
A Layer in Photoshop can be created to make changes in stages that are organized on separate overlapping images. Photoshop layers are like sheets of stacked acetate. You can see through transparent areas of a layer to the layers below. You move a layer to position the content on the layer, like sliding a sheet of acetate in a stack. You can also change the opacity of a layer to make content partially transparent.
A histogram is a graphical representation of the distribution of numerical data. It is a kind of bar graph. In photography, a histogram is a graphical representation of the tonal values of your image. In other words, it shows the amount of tones of particular brightness found in your photograph ranging from black (0% brightness) to white (100% brightness). As shown in the image above, dark tones are displayed on the left side of the histogram. As you move rightward, tones get lighter. The middle portion of the histogram represents midtones, which are neither dark nor light. Vertical axis of a histogram displays the amount of tones of that particular lightness.
Levels is a tool in Photoshop and other image editing programs which can move and stretch the brightness levels of an image histogram. It has the power to adjust brightness, contrast, and tonal range by specifying the location of complete black, complete white, and midtones in a histogram.
Curves is best applied as an Adjustment Layer. Go to the Layers Panel, click the Create Adjustment Layer icon at the bottom and choose Curves. Now your original image remains untouched. The Curves adjustment layer is one of the most important tools in Photoshop. It’s the best way to adjust the brightness and contrast of your images.

Crop Tool The Crop Tool works similarly to the Rectangular Marquee tool (see above if you have no short-term memory). The difference is when you press the [Enter/Return] key, it crops your image to the size of the box. Any information that was on the outside of the box is now gone.
Clone Stamp Tool This is very similar to the Healing Brush Tool (see above). You use it the exact same way, except this tool doesn’t blend at the end. It’s a direct copy of the information from the first selected area to the second. You need to hold the ALT key down and click to designate where you are cloning from.
Crop tool: It’s used to lighten whatever area you use it on, you can vary the brush size, the exposure amount, and have it effect on the highlights, shadows or midtones of values.
Magnifying glass tool: You can enlarge or reduce the image on the screen, you may have to select a plus to enlarge or a minus to reduce size. This is great for seeing fine details.
The eraser tool will erase whatever you wish in the layer you are in, you can vary the transparency of the effect.
Aperture Priority (A): on camera settings dial. An exposure system used in some automatic cameras in which the aperture is selected by the user and the appropriate shutter speed is controlled automatically.
Manual (M): The camera is set so you have to set the shutter speed and the aperture.
Shutter Priority (can say TV for Time Value):a system used in some automatic cameras in which the shutter speed is selected by the user and the appropriate aperture is then set by the camera.
Bokeh is the official name for a specific photography effect, seen below. The name actually comes from the Japanese word for blur or haze. It requires large aperture settings to get a good bokeh background (shallow depth of field). Large apertures let in so much light that there is much reflection and unfocused backgrounds occur. If you want a deep depth of field, everything in sharp focus, a small aperture would be used.
