A couple of final images from me.
There have been many comments about the very slim depth of field in close-ups. I decided to photograph this pin on Fabi’s hat using telephoto close-up. The pin is too big for the Moment Macro. It measures about 1.75", or 4.5cm. It has quite a strong dome shape. With the centre being about 1cm higher than the edges. Bad news for getting it all in focus with the regular closeup lens. With the telephoto lens I had a much greater lens to subject distance and the depth of field was enough.

I photographed the pin by a south facing window, but not in direct sun, somewhat cloudy. There was a reflector added to the shadow side to even the exposure.
I had another purpose for photographing the key but something happened that made me think it was a worthwhile example.

You probably know I’m a big fan of using a white balance card to get the right colour in photos. In the first photo I measured the colour temperature of the light and locked the setting (just press the WB button in PureShot with a white balance card in view), It looks very much the way actual colour looked.

I was finished with my photo and was about to put things away when I cancelled the white balance setting, I reverted to the regular auto white balance, and I really noticed a sudden change in colour. The red when towards cyan and the key lost the nice brass colour. So I made this second photo with AWB. This is how the picture would have turned out if I had not made a custome white balance. If you have any large single strong colour in the picture the auto white balance will go wrong.
Imagine the standard photographic colour wheel. Just in case you can’t imagine the photographic colour wheel here it is.

The 3 additive primaries - Red, Green, Blue. And the three subtractive primaries - Cyan, Magenta, Yellow. With AWB, or auto white balance, the camera tries to find a neutral balance with the colours in the image. When there is an imbalance the AWB identifies the direction of the colour shift and adds the opposite colour to reach equilibrium. In this case Cyan. So it adds a bunch of cyan to offset the excess red and ends up ruining the colour.
