Exposure Detective

Today's challenge is to look at a picture and try to determine what aperture and shutter speed was used. I have given you some tips and clues below to help..

Example:

My Comments: I think this picture is using a fast shutter speed between 1/500 and 1/1000 because the quickly moving subject is frozen.  The background is out of focus so this tells me the aperture is on the larger end, between f2 and f4. You would also need a wide open aperture to get enough light into the camera in such a short time span.

Clues for Shutter Speed:

• is anything in the picture blurred? Use your judgement and decide it blurred because a very long exposure like 8 seconds or blurred because the subject is moving extremely quickly? In the case of fast objects blur can be captured at even 1/100 second exposures.
• is their a panning effect? Chances are good you have a slow exposure .
•  is the subject frozen in a way that would normally happen to quickly to see? A very fast (1/500 -1/1000) exposure was probably used.

Clues for Aperture Settings:

•  is there a shallow depth of field ? (An out of focus background?) This is a clue that a large aperture ex: f2.8 was used.
•  Is everything near and far in focus? The opposite is true.

Overall Clues:

• Pay attention to the light. If the picture has an obvious high shutter speed and is nice and bright this means that the aperture must have been wide open.
• Remember your own experiments, what settings did you use?

Grade 12 Project: Photos That Make People Think

As a last in class assignment you will but manipulating one of your photos using the "Rasterbator" program. This software takes an image and rasterizes it (Think Lichtenstein Pop Art) so that it can be blown up to a much larger size.

The focus of this assignment is to draw attention to an issue you feel needs to be highlighted in a social setting. Examples of locations include: the school, inside or out, streets in Grimsby (only with permission of property owners) the library,  and other public buildings. the image is blown up and printed on paper, cut out and put up on a backing. Remember you are not limited to walls, think about using 3-D surfaces as well (Ex: a park bench) The image must be your own. To "hand-in" take a photo of your installation "in situ" and post it on your blog along with an explanation of your intent. Posts must be made before midnight on Friday.

Grade 11: Hue and Saturation Assignment

Grade 11s,  your final in class assignment is based on the lesson we did in class today on using the Hue Saturation editing options in Photoshop. The assignment is very straightforward in the editing sense. It will be marked with emphasis on the creative and artistic effect you achieve. 

The assignment is to take a photograph over the weekend or during Monday's class that you intend to edit for colour. The edit must do one of the following things but only one:

• Desaturate all colours in the image except for one. This will result in the a black and white image with only  (for example red ) tones showing  through. Ex:

• Isolate one part of the picture with a selection tool, feather and leave only this in colour. Note the difference in the effect.

• OR you can isolate part of an image and play with altering the colour in an interesting way. Ex:

You will be graded on the quality of your original image as well as the overall effect of the edits. Pictures that have poor composition or colour edits that appear to be random or without purpose will lose marks.
