Can’t figure out why the “Sunny 16 Rule” doesn’t work so well on my 5D/IV. The lens is Canon 70-200 F4 L/II.

Conditions: Bright, sunny, mostly clear sky. All three shots SOOC.

First (IMG_3321): A Priority, F16, 200 ISO, 1/20 Exp (Yes, 1/20th SS)
Second: (IMG_3322): Manual Mode, F16, 200 ISO, 1/200
Third (IMG_3323): Manual Mode, F8, 200 ISO, 1/200

Comments?

Thanks

#2 & 3 have the same settings but totally different results.....What about exposure compensation...?

Icorrected orig post for Fstop to F16.

Explain pls.

A bright, sunny day but your subject is limited to darker colors, absorbing the light. You didn't shoot a typical "scene" with varied light and dark elements averaging out. See:

Did you do any post processing?

Do you have some sort of darker filter on your
lens?

??? I desagree...see, N°2 is shot at f/16 while N°3 is at f/8...ISO and SS remaining the same in both cases.
And N° 3 is effectively much brighter (by 2 stops?) than N°2.
Question is: why N°1 can be quite OK at SS 1/20 sec...where 1/200 is expected???
I also suspected Expo' Comp'...or something with bracketing settings?
Anyway, strange results!

For info;

Shot 1 - +3.3 EV more exposure than Sunny 16 (the result being closest to what we would expect)
Shot 2 - Sunny 16 exposure (note this is the darkest exposure)
Shot 3 - +2.0 EV more exposure than Sunny 16

So, based upon time of day, the lighting conditions you confirm and the scene content it 'appears' your system is 'underexposing/reducing the image brightness' of each shot by approx 3 Stops.

There appears nothing in the Exif I can see to suggest why.

I assume you do not have an ND filter or polarizer attached? I wonder if there's a possibility that the lens is stopping down to a smaller aperture than that indicated, does it do the same with a different lens?

This chart says only the middle image, the dark one, was using the sunny 16 exposure parameters. The first is wrong for the shutterspeed. The last is a better exposure, but 'wrong' in the sense f/16 is now f/8, see the exposure setting of 'poor lighting'.



Stepping away from the technology, what are you trying to accomplish? This view of trees against a blue sky, assumed to be sunlit trees, does not need f/16 on a digital camera. Regardless of the exposure being used, f/16 will soften the details of the image due to diffraction.

When it comes to exposure, why not use the modern digital technology right there in your two hands?

If you want to use f/16 (or any aperture) in aperture priority, just set that value, hold the camera to your eye, focus, and look at the meter reading in the view finder. If the meter does not register 0 or something between 0 and +1 (aka to the right), adjust your exposure until the meter does register at zero or to the right, between 0 and +1. If you want to shoot in aperture priority with a fixed ISO, just turn your EC (exposure compensation) until the meter registers between 0 and +1.

BTW - I checked only the first image in DPP. No EC was used and the camera was using a center-weighted average metering. The approach above of viewing and adjusting how the exposure positions the meter is valid for all metering modes, but possibly your metering mode selection impacts how the camera behaves if you don't make informed adjustments as the human decision-maker in the equation.

BTW2 - the current firmware for the EOS 5DIV is 1.3.3.

BTW3 - at 1/20 sec, the EF 70-200 f/4L IS II should still capture a sharp and stabilized image at 130mm and this slow shutter. Was the IS active and were you using good shooting technique in terms of holding the camera steady?

Pls review orig post. The answer is : no

My orig post was incorrect at Fstop, which I subsequently corrected.
