Hi and thanks once again for your feedback,
The Fungus was on the north side of the tree and it was mid morning on a sunny day, so I suppose I was on the back foot to start with, but I kind of hoped the leaves would help me out a little in terms of blocking the light. Last time this happened I managed to get around it oddly enough by changing from spot or centre weighted metering to Elvalutive/Pattern metering.
Luca - Yes I agree the second image doesn't look right, it looks a little yellow if you ask me, would you agree??? I took the image that looked very much like the first and just played around in photoshop. Unfortunately still reading the manual and I have got as far as Layers, so plenty ahead of me as yet. Its a bit like the blind leading the blind at the moment.
Bob - Wow how did you find that out !!!!! I'm truely amazed. Anyway I was shooting using a Tameron 28-80mm lense mounted on 13mm (iirc) extension tube. I used a high aperture setting to increase the DOF, I wasn't aware of the Diffraction effect. Everything I have read implies smaller aperture greater DOF and increased sharpness, another learning curve to hop on !!!!.
Thanks for the link, I've had a quick look but will have a proper read through later. Is this the same site that the WB info was on ?
I wasn't aware of any better performace of lenses between certain apertures, are their any manufacturers guide available on this do you know???
Thanks once again for your feedback, happy to learn !!!
If you want to edit any of my images to demonstrate points/techniques to either myself or others please feel free to do so.
Still learning with Canon 40D, 28-135mm, 100-400mm L and Elements 6.
Any Advice greatfully received.
