Ann - Rosa

1/125, F8, ISO100, levels adjusted, sharpened

I have just been processing a post for tomorrow which is me experimenting. Its good that you post this now. I might put mine up this morning instead of tomorrow for a direct comparison of problems.

There is something not quite right about your stats, Ann. Here is how my thinking goes. If you have an ISO=100 then it is a bright sunny day and you are closing down the light for this reason. Yet you only have the aperture set to F8 whereas I would think it might be better at F11 or even more for an ISO=100. Because Rosa is not doing anything other than looking at you take the photo, it is not necessary to have the s/s set as high as 1/125. So: as my tendency is to choose the aperture for the conditions (or the s/s if action needs to be frozen)then let's settle on F8. I would then have set the ISO=200 and decreased the s/s to something like 1/60. All this would have let a lot more light in and decreased the need for post-processing.

What do you think?

I will post mine now and would welcome your critique of it.

I think I opted for F8 because I wanted to make sure I got her alpenhorn. I really wanted the whole thing but didn't have the lens with me to do that so I ended up settling for this composition which I like but I think with this composition I should have opened the aperture and blurred the background a little. 1/125 is the setting the camera gave me as correct. I suspect I metered off the wrong area, figuring out where to meter is something I'm having a lot of trouble with. I'm going to go back to evaluative metering instead of centre weighted and see if it makes a difference.

This one also looks darker on screen than it actually is.

How do you mean metering? Point at grey and that is the s/s for the chosen aperture?

I think I have to do more reading as I shoot ... I read my last manual as I trained from London to Avignon ... that's the problem!! Need foreign climes ...

Its what part of the scene the light meter in your camera (the line with the divisions (-2, -1, 0, 1, 2) uses to determine what it thinks is the correct setting for that scene. What it is using to give you the 0 reading. I'm shooting when the camera says its correct but its coming out dark so I suspect I'm metering on the wrong place. I've been using centre weighted (which metres off a smaller area) but am going to see what the camera does when I use evaluative which takes some kind of an average of the whole scene. I find this area really difficult to get right.

Any thoughts, Peter?
