Spoonbill Aperture Quiz « Arthur Morris/BIRDS AS ART

Spoonbill Aperture Quiz

Stuff

We enjoyed a lousy morning of bird photography as a west/southwest at 25+ mph sandblasted our eyes and had all the birds facing away from us and the light. Our sunny/hazy afternoon turned into a cloudy early evening; we enjoyed a great session with lots of bathing godwits, three totally tame spoonbills, and lots more.

For the first time in weeks, I was too tired to finish a blog post the evening before. With the forecast for stormy conditions and more morning west winds I decided to head to bed early and stay in on Monday morning. This blog post, the 109th in a row, took about 1 1/2 hours to prepare. It was published just before 5am on Monday morning.

Canon’s Huge Megapixel Bodies

Many of you have read about the two new Canon 50+ megapixel bodies, the Canon EOS 5DS DSLR and the Canon EOS 5DS R DSLR. The two cameras look, sound, and pretty much are quite similar. I have withheld commenting until now because I did not have a good–heck, I did not have any–understanding of the single difference between the two bodies, that being the Low-Pass Filter Effect Cancellation.

    Haven’t read any of the comments above but I’ll take a stab at f8. Your exposure for white in sun is 1/3200 f8 ISO 400. Shade or cloud needs about 2 to 2 2/3 stop lighter. So 1/3200 to 1/1000 = +1 2/3. ISO 400 to ISO 640 = +2/3 Total +2 1/3 The whole image in general seems lighter than middle tone and there is just a little white. So +2 1/3 should be enough, therefore leave aperture at f8.

    Hi again Artie.
    That is such a great shot. I can’t believe we are all making such a meal out of the shot details.
    I checked the sunny 16 rule and it says F 16 for sunny , ISO 100 shutter 1/100!
    So your normal starting point for your test exposure is the same exposure as this using F 6.5 ISO 400 and 1/3200 shutter.
    Its bright here today so I got my camera out and played with the settings.and indeed these two different sets of values give the same exposure value. At least within a third of a stop.
    So my new deduction is this. Your exposure value should be roughly similar to the above rule for a cloudy day. I’m unsure weather we need to factor in the amount of over exposure you have dialled in above the cameras meter. Since it comes down to a hard number I thinks this might be a distraction.
    Whatever, the rule gives ISO 800 1/1000 , f8. For cloudy.
    Therefore at 1/1000, ISO 640 your camera meter gives you f7.1
    Shooting + 2 EV above this would yield a value of f 3.6.
    So now I have one leg on the boat, one on the dock and one in the water.
    Someone needs to,save me soon.:-)
    Regards
    David.

    My head is still spinning from the IPT. Thanks again Artie what an experience. That spoonbill you got is fantastic.
    All of the bird seems to be razor sharp and I sense the grass was as well before you applied the blur technique plus the bird
    Is landing or flapping and wings are sharp. I would say because of all those points
    You used f9 to give lots of dof and still keep it sharp with 1/1000 shutter speed.
    Thanks again for a great three days it was an awesome group and my wife and I met some folks who I’m sure we will be life long friends with, including
    Of course yourself!
    I will send some shots of you soon.
    Cheers Lisa and Craig

    Boy am I dumb. What does the posted jpeg size (from exif) 1200 × 800 have to do with anything? I don’t know the answer to the question, but I’m pretty sure the 7D2 crop sensor will effect the depth of field? Another question regards center AF point on birds eye was active so this image has been cropped to move the bird back to the left in frame?

    • avatar Arthur Morris/BIRDS AS ART

      As for the EXIF, I should have written that the answer is in the published EXIF data, that is the ISO and shutter speed… Yes to crop bodies increasing the d-o-f. As to the crop, you are exactly correct. a

    • avatar David Peake

      Ok William,
      You are in the company of many others . I’ve looked hard and still don’t know how to put together pieces in a logical explanation.
      I think you are right about the slight crop on the left b/ c the birds eye is not in centre frame as displayed,however Artie says it is as framed.
      My answer is instinctively that it should be f2.8. But why?
      The conditions are described as borderline crappy. Does this describe the light at all or only.? Or is this meant to encompass the cloud cover, time of day , wind strength an direction all of which have a bearing on the final ” firing solution”.
      Assembling the facts.
      we are given 1/1000 and ISO 640
      We know from the exposure triangle that these work together for a given exposure by one goes up and the other goes down so they balance each other.
      Arties preferred shooting starting point in good light is 1/3200 , f6.3 and ISO 400.
      Since he’s shooting in this instance with several stops slower shutter and going for a higher ISO , I think he has compromised on shutter speed( lower ) and ISO ( higher) . He has had to work hard to get a usable shutter speed for the flying bird even though it’s at its slowest just as its landing as it is here.
      So putting aside the discussion on depth of field, I believe, in this situation I would go for wide open, F 2,8
      If he used some other f stop he will let us know what and why in due course, and if it’s not 2.8 he will have a good reason and an even better explanation.
      Cheers
      David

      • avatar Arthur Morris/BIRDS AS ART

        Crappy was referring only to the light. Wind was pretty good and the birds were great. As for the rest it is amazing what happens when you consider all of the available information and put your thinking cap on…. Still withholding my comments for now 🙂

        artie

  • avatar Warren

    I would say wide open at 2.8 because you had bad light and only adjusted ISO about 1/2 stop. The 2 stops different from your starting point only equal the 2 stops above the meter. But do not take into consideration the poor / cloudy light. That requires about 2 more stops which gets us back to wide open (2.8)!

    Warren

  • avatar J L Turner

    Since it was borderline crappy light, you probably needed about two and 1/2 to three stops more than on a sunny day. Your starting rule of thumb for a sunny-day spoonbill, previously published in Bulletin #473, is iso 400, f6.3, 1/3200 sec. Going to iso 640 and dropping to 1/1000 gets you about two stops and you went evaluative +2 stops, so I would say f6.3 would get your needed exposure.

    • avatar Arthur Morris/BIRDS AS ART

      You gave it some thought but you and everyone else are missing some obvious considerations….

  • avatar Frank Sheets

    DOF for a 300mm lens at f/4 is about 5′ at 100 feet. Guessing the length of the Spoonbill in that range to be about the same and the birds body is in focus and foreground and background is out of focus, f/4 seems to be a pretty good guess.

    • avatar Arthur Morris/BIRDS AS ART

      I am not saying right or wrong but there is pretty much no need to guess 🙂 a

  • avatar Leonard Malkin

    I would say F4 as both foreground and background are fuzzy indicating a shallow depth of field.

  • avatar Scott B

    Artie,

    You say take a look at the EXIF data because the answer is there. Hmm…

    If the resolution is 1200×800 (the only EXIF data available), and you were starving for light in time of day and poor conditions, I’d say you are shooting at f/4, maybe even wide open at f/2.8.

    There may be some blur selectively applied to the image, but if you were farther away, and you didn’t apply any blur accidentally to the Spoonbill wing, the tips are blurred. You’d probably need more light from the lens if you’re +2 stops exposure as well.

    I’m a more experience-based learner, which is why I am coming to Nickerson, so apologies if you bluntly put this calculation out on a blog and it didn’t sink in.

    Back on topic, distance guessed by your final image size (1200×800), blur on the bird, and need for light, I’ll make a decision and say wide open at f/2.8.

    Crossing fingers,
    Scott

    • avatar Arthur Morris/BIRDS AS ART

      Hi Scott, Ah, your comments get me to see where I might have mislead folks. I should have written that the answer is in the published EXIF data… Please note that I am withholding judgement on your answer…. artie

      • avatar Scott B

        This has been killing me all day.

        I’ve come to this conclusion based on your published ISO and shutter speed.

        You were constrained at f/2.8 for light and needed to increase ISO until you reached your desired 1/1000 shutter speed.

  • avatar Tony L

    Looks overcast … I’d say f4 at hat ISO/shutter.

  • avatar Stu

    Largely because of the OOF vegetation in the foreground.

    • avatar Arthur Morris/BIRDS AS ART

      Good try but I selectively applied a Gaussian blur there with a Hide All mask and a soft brush. But that ain’t it. It was pretty well out of focus but I wanted to soften it up a bit. a

  • avatar Stu

    To,clarify my response, I guess f/4.

  • avatar Stu

    i am in David Peake’s camp — both regarding the data on an iPad and with my guess on the aperture.
    Best wishes.

  • avatar David Peake

    Hi Artie ,
    let me be the first to reply.
    I have yet to learn how to view the EXIF data on my iPad .
    However I’m picking that you are aiming to balance the need for speed with depth of field considerations.
    So I vote for one of either wide open or more likely f4.
    To me it looks like you are shooting in light that requires about four stops more exposure than a typical bright day.
    Regards
    David

      There was a recent blog post on this very topic 🙂

      ps: if I forget to remove the EXIF and you get the answer by looking at it that smacks of cheating and deprives both you and the rest of the gang from exercising their brains. Someone posted the answer based on the EXIF. I deleted the comment and wrote him asking him if he thought that that was cheating :). He apologized. I often remove the EXIF for quizzes but here I had to re-do the JPEG. Five minutes extra work 🙂

      You beat me to the punch.
      I was thinking sunny 16 too. But too embarrassed to say so.
