For this first shot I wanted to show the bluebells in focus front to back. However being in the wood in bright sun was difficult light wise. I thought of the Light in Zones and took readings to give me a good shot of exposing the whole scene correctly. I have included these shots at full size so you can see the depth of field and detail in each shot.
My second shot was more evenly lit but the wall was quite dark. So I set up the camera on the tripod and sat and waited for the sun to light up the wall. Then triggered the camera with a remote shutter release.
This third shot shows a weed as a thing of beauty and as the whole field is in focus the beauty fills the shot front to back. To get good clear depth of field I waited until the right atmospheric conditions to get deep depth of field. I walked 10 miles with lots of lenses and my tripod so it was an all day adventure. I aimed to use F16 to capture my shots but also experimented with F22 but found the results too dark.
