Title says it all:
what do you think?
should of gone HDR
lol thanks for the tip!
Looks like a snapshot with nervous bokeh to be honest. Focus is good and the subject appears sharp though.
I got an HDR portrait somewhere in the back of my flickr page that I did a few years ago and...yeah...
It makes people's faces look like the surface of the moon...
it WAS a snapshot I didn't really want to "pose" her, so we were just walking around taking pictures of each other.
what do you mean by "nervous bokeh?"
oh hdr your idea very good
If it was just a snapshot than I wouldn't call it a "portrait attempt", to me that means you set up the shot. For me it changes the way I critique, for a snapshot this is very nice, for a portrait shoot it needs work.
Nervous bokeh = not creamy, shaky.
sorry... I will retitle the thread. I didn't really set anything up.
how do I change from nervous bokeh to creamy?
Yes, it is nervous bokeh. It's a characteristic of the Canon 50mm 1.8 EF-II lens and its overcorrected spherical aberration, which makes the images very sharp, and the clunky five-side diaphragm that the lens also has. Nervous bokeh doesn't look too awfully bad on a smooth, monochrome hedge like you have in your photo's background. Some backdrops would have made it much more intrusive.
Nikon's 28-200 G series zoom has the same issue of overcorrected spherical aberration, which makes the lens bitingly sharp at its best focal lengths, but it does not have the 5-bladed diaphragm like the 50 EF-II, but a 7-bladed one.
This article compares Canon's 50.1,4 EF versus their 50/1.8 EF-II, and has some nice photos that show how a 5-sided aperture renders out of focus highlights in the background Canon EF 50mm – F1.4 vs F1.8 MK II - photo.net
One of the odd things about bright,green hedges is that the leaves themselves often have subtle highlights on them from the sky, small reflections if you will, that will disappear with a polarizer is used. Those highlights tend to render badly with the 1.8's five-sided aperture, not as graphically as with the lights at night as shown above, but enough so that the bokeh is not creamy, and the rendering is not what is called "with a roundness of detail". Canon's 85/1.8 EF gives much smoother bokeh than their economy 50/1.8. One of the *worst* 50mm lenses for bokeh is the expensive Zeiss 50mm f/1.4--it has a Double Gauss optical formula, and is very sharp, but the bokeh is extremely harsh and hashy.
it probably didn't help that I sharpened the photo... if I had known it was a big deal, I would have done NR on the background... I'll remember that for next time.
