Some old habits just keep reappearing and are the explanation for why I occasionally make pictures like these. When I use to make travel videos I always tried to capture images that I could use for backgrounds on title pages. It was a good idea then, and still is if you are making videos or presentations with title slides or text. It helps to leave either a clean area or have a uniform texture to be used in the backgrounds. On slides with images like the leaves, I would usually lighten them up and use a contrasting color for overlaid text.
The garden clean-ups have started. This is one of the gardens down by the dog park. It is cool today and it is raining so I’m using an old picture I found as I was going back through and cleaning up some of my recent pictures. That is one of Homewood at Plum Creek’s buses on the left.
I have been using my Olympus PEN-F camera in the program mode with the electronic shutter and auto ISO in order to keep my photography silent when photographing around people in changing light conditions. When photographing this way, I noticed that the camera’s bias is towards selecting slow shutter speeds before raising the ISO level. Often the shutter speeds were too slow to stop subject motion until Olympus published the software update that enabled me to set a floor level for shutter speed.
While trying some other features of the camera, I noticed something. The camera appears to have a different program curve for different shutter mechanisms; i.e. the camera selects different values for ISO and shutter speed for different shutter types.
The literature is clear about the effects of rolling shutter effects when using the electronic shutter. In addition, the specs show that faster shutter rates can be obtained with the electronic vice mechanical shutter. Based on that information I assumed that when using the electronic shutter that the chosen shutter rates would be faster than those used with the mechanical shutter, if the camera software used different program curves. Not so. The reverse is true, at least in some sections of the program curve. When I used either the mechanical or the hybrid shutter the chosen ISOs were higher as were the shutter rates. I expect that the reasons for the different program curves have to do with shutter shock, etc. Olympus is probably biasing the different curves to minimize the issues that arise when using different shutters.
Has anyone found an explanation of the differences between the Olympus program curves that are dependent on shutter modes, or does anyone have some other explanations?

I made these pictures early Sunday afternoon between the morning showers and the later rain from Nate this morning. I don’t post many pictures like these and some have wondered why. The main reason is that I have posted many in the past … especially in the years after I moved here in 2011. One of my reasons for posting pictures from around Homewood is to show others, who live here, various images they didn’t, or couldn’t, see. Since many see images like these shown above, I mostly try to post images that are of the details that others might have missed.
