May - Spring Flowers

While my square foot vegetable garden is beginning to bare fruit, more flowers around my house are blooming each and every day. I guess the old adage, "April showers, bring May flowers", is mostly correct.  There wasn't much rain in April but there are May flowers.

Depth of Field at the Garden Shop

During my lunch hour the other day, I stopped by the garden section of my local home improvement store.  I just happened to have my camera with me.

Below are a few examples of how the relationship between lens focal length and aperture relate to depth of field.

Colorful tomato cages 200mm @ f/13

I changed the focus from the yellow to the blue cages and lowered angle a bit.  The yellow and red cages seem to be in focus less than when the camera was focused on the yellow cages.  You will need to look into hyperfocus.
200mm @ f/13

At a long focal length, 200mm, the depth of field is shallow even at a rather small aperture, f/13.

I used a shorter focal length here, 42mm @ f/4.4

Here the aperture is close to wide open, f/4.4, the depth of field is greater then the above two photographs because of the shorter focal length.

Pelargonium 135mm @ f/22

Here again, long focal length decreases the depth of field.

Try some test images on your own camera.
