Hi Mirenchu
I like the bird's pose, did well with the bg, great head angle and lots of feel Could only wish for more room around the bird particularly for the virtual feel !! I like it a lot !!!
lots to like here - composition, exposure, HA and action - agree with AL just need some more room at the bottom for the virtual feet.
Good show :)
Lady Mirenchu,
I like the composition, image and capture, I like to open wing position and the fine details displayed...the color rendition is good and so is the low-key complimentary background...My only suggestion would be to tone down the hot white area on top of the bird's head...aside from this, you did very well, proud of you...:):cool:
Mirenchu, Nice details and pose, Agree w/ more room for virtual feet.See some halos around wings also.
Nice pose Mirenchu. Other techs mentioned. The bird has a beautiful wing spread, just see some cloning marks or something on the back wing from blurring the BG a bit?
This is a great capture, but it has two main problems resulting from blurring the background.
(I'll be the first to say that is a tricky effect to pull of convincingly, so don't feel bad.)
First, blurring the background left some halos and other artifacts around the edges of the subject. There
are several ways to avoid halos, depending on what kind of blurring you use. If you use lens blur, that
has a feature that recognizes a layer mask and prevents halos. If you use Gaussian blur, that requires
a more elaborate process to prevent halos.
Second, blurring isn't consistently applied. Here, for example, the legs and the leaf at left are both
on approximately the same plane -- same distance from the camera -- yet one is blurred while
the other remains sharp.
David, How do you eliminate the halos w/ Gaussian blur? Also are you saying that lens blur is better for BG blurs? And can you use that w/ a layer mask w/ the same results and if so what settings? Sorry for all the questions but since this is a very important part of most images(the BG) I feel it is important for us all to learn the correct way to blur a BG before we get comfortable doing it the wrong way-that's assuming there is a right /wrong way to do it. Thanks again sorry for all the questions!
D, I think lens blur is better for BG's from what I have read. Seems to give you more realistic DOF. Haven't done it a lot so maybe the expert will chime back in :)
With G/blur, the whole image gets blurred, even with a mask. All the mask does is hide what is directlyOriginally Posted by denise ippolito
behind it. So you have to allow for that. There's a tutorial in my list of mini tutorials (in OOTB forum) called
"blurring a background." Here's the link. It shows how to avoid halos when using G/blur on a background.

In the lens blur dialog box, there's a drop-down menu. If you choose the "Layer mask" option, that
prevents the blur from affecting what's behind the mask, so no halos are generated (if the mask
is drawn accurately). Also, many feel that lens blur creates a more realistic bokeh.
Here's a thread on dpreview that discusses the halo problem.

Thanks David, I thought that tutorial was only for lens blur-I didn't think it would be the same for gaussian blur. Good to know! Also thanks for the layer mask tip.
Mirenchu, I like your composition and the effect you were able to create for the background.
Congrats
