Over two years ago I posted some photos of roses on the second page in my macro thread
It was interesting to see the difference between lighting conditions on an overcast and a sunny day.
1/60 - f/8 AP- ISO 200
The same rose I had shot two days earlier in sunny weather. The difference is quite dramatic. I had the sun in my back and in order to shoot it from the same angle I had to cover it with my shadow. But even then the much higher contrast creates a very different photo. The shutter speed was the same as two days earlier but the ISO was 64 instead of 200 so there was almost four times more light. And it shows. I shot it from slightly further back that time.
1/58 - f/8 AP- ISO 64
Overcast again. Lovely creamy colours.
1/52 - f/8 AP- ISO 200
I also wanted to shoot it in its entirety and wanted to isolate it as much as possible from the tree in the background so I went right to the other end of the aperture scale and set it to f/3.5. The soft light is very flattering again and the contrast against the dark background makes it really stand out. This photo looks best also against a black background but I cannot change the colour of the forum page. This photo is the only one that I slightly cropped before I resized it.
1/280 - f/3.5 AP- ISO 200
Again two days later in sunny conditions. Not covered by shadow this time. Again quite a different picture. In one of the shots this little insect very helpfully decided to pose for me for an instant. So I chose this one.
Surprisingly enough the live histogram told me that no exposure compensation was necessary. The lightest parts were a safe distance away from the edges of the histogram. All photos were shot at EV 0.
1/1400 - f/3.5 AP- ISO 64
Grey overcast days may look very dreary but they can offer a very flattering light. No harsh contrasts and in these photos it allowed for a beautifully subtle tonal range. The pale light of that grey day made for some rather nice pictures.
When in doubt..... Press the shutter.
