Black and White Sunday: Rainy Day

It's a rainy day…perfect for a Busy Bone and messing around with the camera.

 Luckily, I used a tripod, since the camera was doing way mysterious stuff.

For starters, I set it to take b&w, which already had me researching the instruction book. Then I set it for Aperture Priority. Supposedly the shutter speed sets automatically…but I also played with the ISO and for no good reason set it for 800.


ISO 800, f 5.6, 1 second

 Well, of course the camera compensated with a long shutter speed. I get that. So, auto ISO it is.
ISO 6400, f5.6, 1/15 second 
What is happening with the shutter speed? Isn't a fairly low f-stop supposed to let in more light? So it's obviously a slow shutter speed because the light is dim, but it wasn't that dim (or so I thought).
ISO 6400, f5.6, 1/8 second
I'm so confused. What is making the shutter speed change? Does setting for b&w have something to do with it?


ISO 1250, f4.5, 1/40 second
Meantime, with all my dithering around, Toby has gobbled down his Busy Bone, and is no longer, um, busy.  So he's done "modeling", and I guess I'll go spend some more quality time with the instruction book :D

    It is interesting how the different settings change it. My camera doesn't have a b and w setting.

    I tried messing around with with the priority modes, but just wound up being frustrated because I couldn't control everything, and therefore wasn't fully seeing why X thing was giving Y result. Messing with full manual mode (and normal color - black and white is incredibly difficult to shoot) really helps!

    I love that last one!!!! That's a moody and thought-provoking photo.

    I think that what is happening is that the camera is deciding on its shutter speed based on one point or a small area of the frame. If that point moves relative to the things in your picture, then the camera will compensate. E.g., if the point being evaluated happens to be on a dark spot in the photo, the camera will make the shutter very slow. Then, if by happenstance that point is on a bright spot next time, it will change the shutter to be faster. This can even happen when the camera is trying to use all of the frame to choose a shutter speed.

    I tend to use aperture priority to get a ballpark for good settings. Then, I switch to manual mode, and I control the aperture and shutter so that I don't have to deal with the odd behavior of a camera faced with a high contrast scene. Does that make sense?

    I did the same thing, I took 87 photos while Easy was busy with a chewing bone ... it's a great time to stay inside and to play with the cam :o)
