You are right! One should not graduate to manual mode but rather like you graduate to auto modes. It takes more knowledge to use auto modes.


Hah. I like the concept of graduating, but in my case, I went from always shooting in auto on my D70s to trying to exert more control, thereby learning more about the science behind taking a self controlled capture. In my way of thinking, we should all always be in a state of graduation.

I think that part of your challenge here is the slowness of the lens from an aperture standpoint. F/5.6 is pretty slow and it also makes the DOF large enough that too much is in focus in your photo and it makes it difficult to separate the bird from the rest of the scene a bit. Unfortunately that is the lens that you have now so you just have to work with it if and until you can get something faster lens wise. I would suggest you get an app for your phone or tablet for DOF. You can get them for free or a couple dollars. That way you can plug in the parameters of the camera, lens and distance and get feedback on the acceptable DOF. The closer you shoot toward the 300mm end of the lens the shallower the DOF will be at a given aperture. Shorter length of lens will give greater depth of field at any given aperture. For example, my DOF calculator indicates that a 1.6 crop camera with a 600mm lens at f/4 shot at 30' has a DOF of 0.11 feet... While a 300mm lens at f/5.6 on the 1.6 crop camera has a DOF of 0.63 feet at 30 feet away. Almost 6 times the total depth of field.

The other thing you can do to deal with the limitations of your current lens is to shoot in RAW and crop a great deal to isolate the subject more. That will not be a great solution with a lot of cropping as you will greatly reduce the resolution of the picture. The other thing that could be done is to use post processing software to reduce sharpness or blur the surrounding elements and isolate the subject more. You can also do that with vignetting tools and use that to frame and isolate the subject.

Best,

Thanks you all for your suggestions and valuable information. Of course this quandary is typical of the relative newbie that I am. Here is where my confusion comes in play. While some of the birds are in motion, it is mostly because I catch them, while they are moving from one branch to another. I am not discussing catching them in actual flight...at least not yet? Lol. Mainly, I have been capturing them from a second-story window (open of course) where they perch against a backdrop of verdant leaves of several bushes on the western side of the yard. My office window is my version of a blind. The lens (Tamron 70-300) is not very fast at 5.6, maximum reach, especially if the light is low, which it often is, given the location of the area these birds seem to favor. But it can render nice images, IMHO.

I tried shooting the birds at slower shutter speeds allowing more light, but then the ISO ended up rendering an image with more noise than I cared for, and the images weren’t as sharp as I wanted. So I figured what the heck and set for shutter speed of 500-800 in S mode. While the image sooc is often darker than optimal, I have had great success in PP. All of this while ignoring the meter. Then it dawned on me that maybe the D7200 software wasn’t actually doing what I thought it was doing, and so decided to ask the more experienced here. Ultimately, this IS the experiment and I am having trouble interpreting the results. I feel the solution is to return to full manual, but often, the time it takes to make the adjustments is twice the time it takes for the subject to fly away.

When shooting birds in flight I like Aperture Priority, let us say I am using 6.3, I then want to shoot at least 1/2500 sec. So I play with my ISO until I get the shutter speed up to where I want it. I use Aperture Priority to knock out the back ground so the bird is isolated. I also use GROUP AUTO FOCUS, continuous auto focus, center weight metering (not spot). If my shots are dark or light, I use exposure compensation as a final adjustment. Good luck and keep on shooting until the end. ie. If I am shooting white birds, I tend to go a +1 on exposure compensation, if my birds are darker, I might go the other direction with exposure compensation.

Shouldn't that be the other way around? If shooting a white bird, shouldn't you go (-) on the compensation to keep from overexposing and blowing out the white detail, and if the bird is dark with a brighter background (backlit) shouldn't you go (+) on the compensation to show more of the detail on the darker bird, rather than just a silhouette? I could be wrong.

Maybe so. But given the distance I am from the subject, and the closeness of the subject to the background, am I correct in saying depth of field vis a vis bokeh will always be at a minimum?

Thanks Todd, for your clear evaluation of the weakest link in terms of my equipment. The lens does a fine job in better light, and I agree better glass would eliminate at least one problem. I always shoot RAW and have a suite of software to use to work on images. I have no qualms about cropping and am glad I posted a full image so you could weigh in. Thanks again!

The meter will try to make everything medium, 18% gray. So it will try to make very white or very dark objects medium gray. It will underexpose the white to make it gray and it will over expose the black to make it gray. For a Snow shot you can usually meter and then overexpose 1-2 stops. I do think camera metering algorithms are getting better at metering at least on the higher end cameras. Just my opinion.

And if shot at 30 feet with those settings the DOF would be approximately 0.15 feet...
But we don't know the distance....

Your welcome...
and get a DOF app and play with it... it is instructive and in part explains why we don't need F/1.4 800mm lenses...aside from the huge size and weight they would have to be...

Whenever I've been confronted with a situation such as you describe, I'll meter something stationary in the same light as the bird would be. My hand works well held over my head and metered. That would simulate the shaded side of the bird in flight. As long as the lighting is similar to that on your hand, there will be no difference in the exposure between your hand and the bird.

If the lighting is changing, broken clouds blowing by, take two meter readings. One when your hand is in shade, the other when in sun. Remember those two settings. Then just switch between the two depending on the lighting, as there is little time to do much else.

I almost always shoot in manual, but lately, I’ve been trying to get bird shots under less than ideal lighting conditions and began using shutter mode. When I do, am I to disregard the meter reading and assume the camera will do the rest to render the best possible shot? I have the same questions about the other non-manual modes as well.

And if you want to set up two setting to toggle between it is handy if your camera allows you to define custom shooting modes. My Canon does and I use that capability...

Nikon has shooting banks that maintain settings, similarly. How quickly one can change between them is an issue when situations are changing rapidly.

Thanks for sharing Bill. I can understand that being your lens sweet spot. Do you have issues with DOF when the birds are very close with at crop body and long focal lengths. I would think the DOF could get very very shallow. I think you have a great combination for birding with the D500 and the 200-500!!!

Todd, with group auto focus the eye of the bird is in focus no matter how near or far. That's what is so great about GROUP AUTO FOCUS. Mind you, I try to get all five spots on the bird, which is not all that hard to do. I used to practice panning on moving cars hours at a time until I had them centered almost every time. And 6.3 gives a lot more DOF than say 2.8. I find that at 6.3 most all of the 4 foot wing span of a great blue heron is in focus from one tip to the other.

Bill, do you know which Canon focus mode is closest to group auto focus?

Thanks for your reply. So I should ignore the meter. Should I then, in response to your statement, also set ISO to auto?


I don't know that I would ignore the meter. In shutter priority, the camera will set an aperture for you but I would still look to see what it is wanting to choose and if the meter shows a proper exposure or not. For maximum flexibility you can put the camera's ISO in "Auto" too but if the light is too low it may choose an ISO higher than you want to use. I would recommend setting the ISO to somewhere in the 100 - 400 range and if the light is too low maybe up to 800. Use the fastest shutter speed that you can and still get a good exposure and if you lens has VR turn it on too.

I recommend using shutter preferred and setting the ISO to AUTO. AND, learn how to hold your camera very steady!
