Exam Pic.

Shutter Speed and Aperature

Shutter Speed:

        The shutter speed on a camera is one of the factors that controls the amount of light in your photograph. It serves as a gate that keeps sunlight from the photo. The shutter speed controls the time that your photo will be exposed to light. A speed of 1/30 means that the photo will be exposed to light for 1 30th of a second. Anything exposure time longer than 1/60, a tripod should be used because your hand is not steady enough for the photo to come out clear.

Aperture:

       Aperture is another factor that controls the amount of light in your photograph. It is comparable to the human eye. The iris is the coloured band around your pupil, this is like the aperture, it can let in more or less light by getting smaller or bigger. The f number you set your camera to will be your aperture setting. A small f number (f/2.0 )  and a large opening for light to enter and a large f number (f/32) means a small opening for light to enter.

Composition

Photo composition is the visually pleasing arrangement of items (or a subject) with in a scene. This can be done in many ways. One if the tips for photography that is highly recommended is using the rule of thirds. Make sure that your subject is not directly in the middle of the picture and make sure that any movement (walking, running, a driving car, etc.) is moving in to the picture, and not out.Also, when taking a picture where a horizon line is involved make sure it is low. Another tip would be using shape in a picture. Shape is when the subject in a photograph had height and width, but no depth. Form would be another composition tip. This is quite similar to shape, but form creates depth for the subject. The use of line would be another composition strategy. Line in a photograph can be used to cause the focus of the viewer to be pulled through a photography (if there is an "s" shaped line), or it can make things seem alive, or taller (vertical line). Texture can be used to trigger emotion in the viewer. The viewer will relate the texture to past experiences and they can relate to the photograph. Lighting is also very important. Natural light can be very soft and very flattering to a subject, but you must keep in mind the position of the sun ( the time of day ) and how bright it is. Studio lighting is also very flattering, but positioning is everything.  These lights can also produce harsh shadows if they are not positioned properly. Finally, make sure you get close, get down to there level and take lots of pictures. You can always delete pictures you don't like.

Natural Light

 Natural light pictures are taken by only using light from Nature (the sun). So no flashes or mirrors are used, although there was a blue colour cast from the lighting, it was easy to remove. This lighting, I found, is actually very flattering to the subject, it is very soft.

What we Learned Last Week

Last week we learned abouut pixilation (or stop motion animation). It is a type of video that consists of multiple pictures being shown for a short amount of time to create the illusion of movement. The amound of pictures used and the time that they are shown will determine how smooth the movement is. Claymation is an example of this type of animation.
