Not really a pet photographer…
Here is a great example of why an overcast day beats the pants off of a full Sun, high in the sky, day.
So here is the family pal, Murphy. This photo was taken at 1:00, or there about, in what would have been full sun. More or less in the direction he is looking.
Murph is full of color, and although in need of a good brushing, his coat shows really well in the cloud diffused sunlight. Also take not of the vibrancy of greenery showing from behind the spindles. Very rich. I shot this 1/250s, f/7.1, ISO 400. White balance? Cloudy. Post process? Mild contrast adjustments – as always – and a very slight vignette to bring more attention to his face. Also cleaned a couple of twigs off his forehead and cropped it so it would fit nicely on my blog. I think this could have been a little longer of an exposure. Maybe. Naw, that’s what he looks like and the green is spot on.
The point. Cloudy days are your friend. Shoot like a fool at noon with the sun behind your back. No worries, your shadow will not be in the pic!
Have shooting!
