I love these shots. They are incredibly cute little fellers. I have one question - have you applied a gausian filter to the backgrounds or was the blurred background the result of your depth of field I'd like to know how you got that effect.
Thanks,
Joan
Hi Joan, the blurred background is due to the very short DOF I was working with. The squirrels were quite close (a few metres away) and the background was quite some distance away as the small log in the shots was on a small rise in the ground (the 'ground level' shots were actually taken resting the camera on a waist level fence). As I was using a 100-400L at 400mm, wide open at f5.6, DOF was minimal. Looking at the shots that look along the log (2 & 5 for example), the log only comes into focus just in front of the squirrel and the shot is going out of focus again by the squirrels tail. That means the useable sharpness only covered a distance of less than a foot.
Having said that, I did apply a touch of blurring to some but it wasn't sufficient to actually affect the level of visual blur. I used the soften brush at about 4 or 5% to flick over the background, not to blur it but to reduce the harshness of the visible noise in the image (most were taken at 1600 ISO). If you look at shot 7, which is a tighter crop and so shows the noise more, you can see the difference around the edge of the squirrel, particularly around the whiskers away from the body. Not wanting to soften the whiskers I went around them, so you can see the background behind them is slightly noisier than that to the left of the image. As you can see though, this isn't sufficient to affect the degree of ' out of focus' blur it just helps give a slightly smoother bokeh by reducing noise (I don't have any software such as noise ninja).
I hope this helps.
Oh and don't worry about the sad face, that happens when you type multiple question marks.
