Shutter Speeds

Here are some shutter speed examples:

The first, Panning with a moving bus with a relatively long exposure time. It's light out so relative to dark situations it might not look like a very long exposure time but for the amount of light it is.


F16 (narrow as possible)
1/8s exposure time


Same conditions. I want to freeze this nice car and I opened up the aperture to let in more light. As well, the background is not as sharp because of the large aperture.



F 2.8
1/320 exposure time.







Here is an example with a human being. The fast action photo with a short time turns out much better than the longer exposure time. In fact the highlights get overblown (bright day) and he still moved so fast you cannot tell what the subject is.

A good example of using a large aperture to direct your viewers attention.

F2.8, 1/200sec exporure









Here is a good application of that in real life.

You can see where Amie is standing, you can see what she's doing. But the mountains/street/clouds don't take away from the subject.

F2.8, 1/640sec exposure

White Subject - White Background

Again, the camera is trying to set the white balance. Because of an absence of darkness, this is the result.
A quick white balance adjustment: and cropped.

Black Scene White Subject

As discussed: When you have a black scene, the in-camera metering tries to find the proper white balance and of course... cannot.

Example:

The tea cup/saucer and shells in this picture are actually white.

You can adjust the white balance (Manual).

Or - as shown. You can adjust your subject into a greyscale image later in Photoshop.

The result... one of the best pictures I took. (cropped of course).

Backlit Subjects

By adjusting your exposure, you force the camera to overexpose the highlights (backlit area) but properly expose your subject... the important portion of the picture anyways.


This would be a good example of trying to take a picture with a strong backlight.




By adjusting the Exposure value... we have fixed the problem of the dark subject.

The first picture was taken with a 1/500 sec exposure (very fast) .
This picture was taken with a 1/30 sec exposure. So 16 X the exposure.




Now you can crop out the overexposed portion of the picture... and your subject looks pretty good!

Studio Work

One main concept we looked at today was how adjusting your camera up and down stops affects your picture. This is a screenshot of my desktop with the 5 images required. The second one down on the left would have been the most accurate setting. 9596

Picture	Aperture	Iso	Exp	White	Meter	Focal Length
9595	4.5	200	1/100	Auto	Matrix	47.8
9596	4.5	200	1/60	Auto	Matrix	47.8
9597	4.5	200	1/25	Auto	Matrix	47.8
9598	4.5	200	1/200	Auto	Matrix	47.8
9599	4.5	200	1/500	Auto	Matrix	47.8

Here is the best picture... cropped of course. (Remember that these files are all compressed etc for the web)

The Pictures Continue

Here are another batch of pictures. It's been tough to get in some time for pictures as the weather has not been co-operative. On a positive note, we are close to setting a record for rainfall.

Early morning light. A corner of my house.











A little park by my house. A small break in the rain allowed me to run out and take this picture.


Taken in early morning light, after 25 days of rain. Tough to get a good depth of field with this subject.





Who says beer makes a bad subject?

DSCP200 - I love this camera

Using the built in macro function.






Taken on a cloudy day, needed a 1/3 exposure time, you get the flowing effect of the water.

Photography Pictures

Welcome to my blog. I just started a photography course at Focal Point and will use this blog to post up results. These pictures unless mentioned were all taken with my Sony DSCR1.

This picture was taking in the dark of night with 15 sec exposure. It is my house and I wanted to get the glowing effect by turning all the lights on.
This picture was taken in the rain last night in a parking lot under construction. The exposure time was 1.600 of a second. I found this time to give me the best result from the light standards (star effect).
This picture is of a neighbours house. It's better landscaped than my own.
This picture was taken indoors. I set the camera to Vivid mode to see what the reds would turn out like. The Vivid mode is meant for outdoor sky and enhancing the primary colours, you can see the effect.
