A Beautiful Day

What a gorgeous day we had for these photos.  The sun was shining and it was a nice 70 degrees.  We went to a city park in Galena Il and luckily everyone was in a very good mood.  The challenge at the park is always to find a nice shady place with no dappling from the sun.  This was done with all available light.  The subject is placed in the lower left quadrant an we have very nice diagonal lines.  I love the happy looks on everyone's faces. 
I wanted the subject to stand out so I chose a small aperture and I had to be concerned with movement so this was taken at a faster speed.  I am very happy with the results.

YUM

This was taken at a restaurant in Antioch Illinois called David's Bistro.  David is an up and coming chef in the area and a blast to work with.  He has such a great sense of humor and an excellent eye for designing his dishes.  His food tastes great too.

Because this is a food shot the first thing we had to consider is the depth of field.  We wanted a fairly shallow depth to bring out the mushrooms and de-emphasize the background.  The shutter speed did not matter as we had a tripod and food does not move.  This was shot with a Canon 40D with a 28-105 lens set at 80mm with an f-stop of 4.  The closer the object of the photo is, the shallower the depth of field.

Okay, now as for the corrolation between the shutter speed and f-stop.  To maintain the same exposure on your subject, each time your shutter is closed down a stop your f-stop must be opened by 1 stop. Example, if you are shooting at 1/125 at f5.6 and wish to have a shallower depth of field-say f4, you must close the shutter down one stop-1/250.  So the first thing you need to do is decide whether shutter speed or depth of field is the most important aspect of your photograph.

Autumn Colors

This was a beautiful wedding.  It took place at the Birdhaven Greenhouse in Joliet, IL.  It was a chilly autumn day towards the end of the leaf season.  We went to a small forest preserve and this is one of the shots that was taken there.

You will notice that the leaves in the background are out of focus.  This allows your subject to pop.  This is achieved by the correct use of the f stop or aperture on your camera.  Your f stops show on a ring around the lens on your camera and run from 1.0 to 32, lenses vary in the starting and ending points for f stops.  Generally the smaller the number (1.0) the more expensive the lens as this can be used in lower light situations. There is a diaphragm inside each lens and the smaller the f stop the larger the opening is on the diaphragm.  This allows more light in.

The aperture not only affects the amount of light that enters the camera, it also affects the look of your photo.  The smaller the number-1.0 (by the way this is considered a larger aperture not a smaller one) the less of your photo will be in focus.  The photo above was taken with an aperture of 3.5 had a used an aperture of 16 the leaves would have been in focus and the bride and groom would have blended in with them. 

Next week we will talk about the corrolation between f stops and shutter speed,
