Simply very excellent. SH, perfect EXP, and a perfect HA. I wold love to see this as a traditional 3X2 cropped from the bottom and the top (with a bit more room above the bird than below).
Love the BKGR and the fact that you were working right on sun angle.
Duane, you have done very well to bring out the real colors of this little bird. The exposure, bkgr, and
detail are right on. I have a hard time with their black and white head in direct sun. This looks great.
Jack
Wonderful image agree with other on the nice HA and BG.
Nothing simple about a chick-a-dee. They move so fast and exposures are tough. This one is really sweet and I like the detail that you have in his (or her) eye. Great that you were able to stop down and achieve good depth of field from beak to tail.
Jack, The trick is to to work right on sun angle.... Doing so makes getting detail a lot easier than if you were working with strong off angled light.Quote:

Duane, nice alert pose, I like the HA, excelent job of exposure and sharpening with those difficult colours.
Steven...HA stands for head angle.
Thank you for the critiques and comments. I struggle to get such a small bird sharp from head to tail but when they turn just right it works. I also think I was working with some filtered light with this image...thin layer of clouds but I can't remember on this exact image.
To get them to stop in their tracks and make eye contact with me I wiggle my left index finger before I push the shutter...it works most of the time and they make it easy because they're used to me sitting out on my deck photographing them.
Although I love the body completely within DOF I'm OK with OOF tails (and many times even more) when the head is sharp (just so you don't struggle too much...)Quote:

Excellent image all around. Techs look great. Nice perch and BG. I agree with Artie's composition suggestion.
Not much of a cloud at the moment of exposure judging by the fairly sharp shadow of the bird on the branch. But any thin cloud helps a ton with B&W birds.....Quote:

Roger
Rog, The sun is more high than off-angled. Look at the spot where the shadow of the body crosses the branch. I would agree with 10-15 degrees off sun angle and with the bird angled towards the light the bird is effectively pretty close to the sun angle; that is why there is pretty much no "sculpting" of the feathers in the image, because the bird is very close to square to the light.

It is this phase angle that gives the fine detail in the subjects feathers.
If Duane can tell us the date, time and location of the image, I can compute the sun altitude (and show others how to do it too--it's simple with a US Navy web site).
Roger
Rog, I do not understand either aximuthal direction or phase angle but do agree that the sun was relatively high in the sky. And I do understand that some folks may learn best using the scientific approach. I do not :)
OOOPS! That should have been azimuthal, meaning how far around the horizon the sun is (e.g. in degrees). For example, you can point your shadow directly at your subject, but if the sun was up in the sky 45 degrees, the angle between you and the sun as seen by the subject is 45 degrees. So the phase angle would be 45 degrees.Quote:

From Duane:
"This image was taken in Chesapeake, Virginia at around 4pm in the afternoon on March 7, 2011. As I stated in the topic I think I was working with a very thin layer of clouds and the sun was over my left shoulder at the time."
It is very simple to compute the position of the sun or moon using this web site:
http://aa.usno.navy.mil/data/docs/AltAz.php
(Note also the data services tab gets other useful data).
On this web page, you simply put in the date, and for US places select the state and nearest city. The site does not correct for daylight savings time. For other places in the world you need longitude and latitude (you can get that from google earth).
Here is the portion of the table for Duane's image around 4pm (16:00) EST.
Altitude and Azimuth of the Sun
Mar 7, 2011
Eastern Standard Time
Azimuth is (E of N)
hhmm altitude azumuth in degrees
1530 28.4 237.9
1540 26.7 239.9
1500 24.9 241.9
1600 23.2 243.8
1610 21.4 245.7
1600 19.5 247.5
1630 17.7 249.2
1640 15.8 250.9
1650 13.9 252.6
(I had to take the : out of the times as funny characters kept getting inserted.)
So the sun was abut 23 degrees high at 4pm (1600), and since the shadows are to one side (say about 15 degrees), the phase angle was around 27 degrees (25 to 30).
From the time of day and shadows, we also know the camera was pointed north-east.
It is the phase angle of about 25 to 30 degrees that gives the wonderful feather detail.

Nice image!
I love this site... I really do, but seriously... does anyone actually calculate the phase angle of the sun / moon before they hit the shutter release?
I agree that the proper angle of light is desired however I never get to shoot wildlife in studio conditions and more importantly I don't want to. It's enough for me to to deal with to make sure that I have my settings correct- like ISO, f stop, shutter speed, head angle, body position, is there trash in the image, can I move to solve some of the visual problems that I see and can I do it without spooking the bird (or whatever the wildlife is that I'm shooting).
I can only control lighting to a certain degree. I can pick what time I shoot. I can try to adjust my angle on the "target" so that it's lit as near correctly as it can be. There are locations where that's easy to do (Bosque comes to mind) and then there are locations where I'm grateful for the diffuse light that comes from clouds (Brazos Bend SP comes to mind). I'm not dedicated enough to wade into an alligator infested pond to get the perfect phase angle of the sun. Probably won't ever be. However I am dedicated enough to go early and try to capture a moment that won't ever be repeated.
I'm with you Michael. Read the light and let er rip :)
Do note that some folks may learn best using a scientific approach. I am not in that group. I use the seat of the pants approach :)
I write programs for industrial control systems. Just about every program will have a routine in it with 50 to 100 lines of code that uses all of those fun things that we were supposed to have learned in school like ARCTAN, COS, etc. Personally I didn't learn how to use that stuff until I had to use it in real life... but I digress...
I love photography for it's technicality and because I don't have to use it's technicality to have fun and every now and then create a decent image.
But- I do agree that learning comes in many forms. I've read the posts of all and I like to think that I learned from them. That's what it's all about in the long run...
PS- Do you have an extra pair of those pants laying around Artie. I think you could auction off swatches of them and make a killing :bg3:
:) on the pants. I have said often that Geroge Lepp has more technical knowledge of photography in one fingernail clipping than I do in my whole brain. And I am fine with that! George BTW is a good friend.

No, we all estimate things and do what we think is best in the field. No calculations necessary.
Regarding phase angle, it is simple to estimate. If the shadow of your head is landing on the subject, the phase angle is pretty much zero. If the sun is off to your left or right, the phase angle is 90 degrees. If the sun is behind the subject it is 180 degrees (backlit). So if you want a 20 to 40 degree phase angle for good front lighting with fine feather detail, choose where you set up at sunrise so your shadow is off the the left or right some. Estimate where the sun is about one-third the way from directly behind toward your left or right for about 30 degrees. If you have trouble envisioning what 20 to 40 degrees is, carry a protractor for a while. I would bet a session or two with a protractor, that takes a few seconds to look at the angles, would be enough, then you could free-style it.
Depth of field is much harder to grasp.
Roger
For 28 years I have been working with phase angles of from 0 to only 15 degrees, with the average very close to zero. And I have done OK with that. 40 degrees off sun angle images rarely work for me and often cause myriad problems.

I would like to see a comparison of images at 40 degrees versus 20 versus 0 degrees phase angle to see what issues come up.
