Cindy, Ernie and I went to the East – West Center on Presidents day to do an Equivalent Exposure shoot. This is to show you how you can change either the aperture or shutter speed and still capture the photo in the manner you want as your original. If you adjust the shutter speed to a faster speed you need to make the aperture smaller. Another example is if you change the aperture to a smaller aperture you need to make the shutter speed slower.

Here is a practical example of how it is best used. You take a photo in Program mode and you like the exposure but the background is too in focus. You want to blur the background some to what do you do. Well you check to see the setting of the original photo to find out that the photo settings were 1/60 sec, at f/16. You want to blur the background some so you may want to use an aperture of f/4 so what is the equivalent shutter speed? Well between f/16 and f/4 is four (4) steps wider (f/16 to f/11, f/11 to f/8, f/8 to f/5.6 and f/5.6 to f4 ) so you need to adjust the shutter speed three (steps) faster. Well 1/60 sec. to 1/125 is one step, 1/125 to 1/250 is the second step , 1/250 to 1/500 is the third step, and 1/1000 is the fourth step. Therefore you equivalent exposure is  1/1000 sec. at f/4.

Aperture steps:

f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22

Shutter speed steps:

15, 30, 60, 125, 250, 500, 1000

By the Way, most digital SLR cameras have two settings for the number of between stops on your camera. Most have 3-clicks and 2-clicks, which mean that between each full step is either three (3) or two (2) clicks. So between f/4 and f/8 there are three or two clicks to go from f/4 to f/8.

Here is one set of examples:

Wide Angle shot from Makapuu Lookout

Well gang after a long absence the KCSPhoto.org site is back. We will be following a different format which is more of a blog site rather than a full blown site. Due to time restraints on my part this will allow me to update the site faster and more efficiently. I hope this will not bother you.

This past weekend on the 21st a small group of us went to Makapuu Lookout for a photo shoot. Here are a few photos which were taken from that photo shoot. Sorry for those of you who were not able to make the shoot but maybe you will be able to join us in September when we go to shoot the Blue Angels.

We had a fun time at the Makapuu shoot but the when we got there the skies were over cast. But even with the clouds hiding the blue skies the clouds gave a beautiful shot. We spent maybe and hour taking photos before deciding to leave to have an early an early lunch at Harbor Village Cuisne. We had a great Dim Sum lunch and thanks to Debra is was free to us because she paid for the lunch. Thanks Debra.

Anyway I hope that you will be able to join us at our next outing. Check this site out for the date and time of the shoot. It will be at Kaneohe Marine Corp Air Stating for the K-Bay fest. I will also be sending out emails to you who are on our list. Hope to see you all there.
