do you routinely exposure compensate in the camera?


John Di Leo

Recommended Posts

On my prior dslr, a d700, I found that setting the exposure compensation to -0.3 yielded a more pleasing image to me. Now, with my new-to-me d810, I find that to get the same pleasingly exposed image, no compensation is needed. If I go to -0.3 the image is underexposed.

did the exposure bias (probably not the right term) change with the d810 vs the d700? Would that be a function of the wider dynamic range?

"do you routinely exposure compensate in the camera?"

 

- Yes! Short answer.

 

It's my belief the D700 used the same metering module as its DX twin the D300, and that therefore the metering nowhere near covered the full frame. I consistently got overexposure and blown highlights from my sample of D700. So much so that it was returned to Nikon UK as faulty, only to be returned saying it was "within specification". Hah!

 

My D800 metering performed slightly better, but I was still only comfortable with -0.7 EV "fine tuning" permanently set on the matrix metering.

 

I don't have a D810, but I find the D7200 matrix metering more consistent and reliable, although still needing an occasional compensation tweak.

 

Personally I think that Nikon's advertised protocol of comparing metering patterns with X thousand preset images is misguided and facile. It's never going to work successfully unless backed by powerful AI processing of a kind impossible to squeeze into a camera with current technology.

 

A simple 'Expose To The Right' highlight protection system would have a far higher hit rate. And such a system has finally been incorporated in Nikon's latest models I believe.

 

Improved DR (getting sick of people banging on about that - it's really been a non issue for years) shouldn't affect the exposure. DR only affects the amount of shadow detail recoverable from a RAW file. Whereas a blown highlight is irrecoverable regardless of how much or little shadow detail is captured.

I often use exposure compensation, to get shadows where I want them. The meter on my Nikon cameras are pretty accurate, but they don't know what I want. I use their reading as a place to start from, just as I do when shooting large format using an incident light meter.

I know that this gets tossed around a bit, but I shoot digital like I do slide film. It needs to be pretty darn close anyway, but as you said once the highlights are gone they are gone. For that reason, I would rather err on the side of underexposing just a bit-with the added bonus that you can recover shadows better in digital than on slide film.

I expect the camera to expose correctly with no exposure compensation. Correctly means if I fill the frame with a gray card the resulting image should have the value of 117,117,117 up to 127,127,127. If it's not it may need calibration or I may set a permanent compensation in the custom settings.

For scene that needs to be expose differently than the meter indicates (i.e back light subject, spot light subject) I would simply switch to manual.

I never use the exposure compensation control.

In landscape I chimp from the RGB Histogram, sometimes re-shooting with compensation. For candids and family events I use face detection AF/AE. Raw files at default EV have sufficient latitude for any minor tonal curve adjustments in post. With each newer sensor/processor combination I'm closer to everything being right in the original file at default AE settings.

Exposure compensation is nice for situations where the meter is fooled.

 

In the case of film, there is a well defined way to rate the film speed, and to calibrate meters.

Yet often enough, for a variety of reasons, one uses a film at a different EI value.

 

There is a different system for measuring the ISO values for digital sensors, and also a different

variety of reasons that one might use a different value.

I've always found that with any camera which uses reflective metering that it is likely some compensation is in order, no matter what mode is chosen. It is a function of what the exposure sensor is reading from light reflected off the subject, not the light falling on the subject. I use incident readings with my rf cameras and exposure is always spot on, transparencies or negatives, same true for digital in the manual mode.

In situations which fool the meter, like back lighting and spot lighting, I prefer to use manual mode rather than exposure compensation. There are times when a landscape seems over or under exposed, but on checking the histogram, everything is usually okay. However for video I use exposure compensation about 80% of the time. There is much less latitude in video compared to still digital photography, and corrections take a lot of time and computer resources.

 

For manual exposure, I use the spot meter setting, and adjust according to the vernier reading in the viewfinder. To save time, I sometimes profile the stage and make adjustments without a formal light reading.

My answer is Yes. I rarely have a subject that has the same "grey" tone across the image area so I adjust the exposure as required. A camera has a greater chance of making the right exposure without exposure compensation for a great blue heron than for a white great egret, all other things the same. I much prefer to tweak things in camera than in post processing.

 

That being said, the other issue is that your two cameras may be metering things differently. To test for this possible problem, follow the advice above: same lens, focal length subject, etc. Use matrix metering and compare the results. One camera could easily be off .3 from the other.

I seem to read/hear a lot lately of chest beating from photographers who consider manual the only "right" way to work their camera.

 

Truth be told, I still use a lot of cameras regularly where even having a built in light meter is optional(or sometimes not an option). I have an RB67 TTL metering prism, for example, but I rarely use the thing as sticks 2lbs right on the top of a heavy camera(that's decently balanced without the prism, but not with). I'd rather use a an incident meter if at all possible when I'm working with medium and large format.

 

With that said, I think those of us who use cameras with TTL meters but built for manual exposure-in my case Fs, F2s, F3s, F-1s, and the like(either match needle or center the needle) do various tricks to get the exposure correct. Truth be told, for me exposure compensation is a "set and forget" value once I've found out how a particular camera's meter reacts. On the above, I tend to point the camera such that the strong backlighting is out of the frame, set the exposure, then compose and shoot. On more automated cameras, I make heavy use of the AE lock button. It's possible to set my Canon T90 such that a half press of the shutter button also locks the exposure-there may be a custom function on cameras like the F5 and F100(and of course DSLRs) that allows this, but I haven't found it. It's certainly something that I've missed in moving to Nikons.

Manual is just another tool in the box. I think it's the right choice for stage plays or backlit subjects (e.g., in front of a window) where you want good exposure the subject. It's also the best choice for a series of group photos (e.g., weddings), where flesh tones and consistency are the most important objectives. Sorry if that seems to be thumping, or something ;)

Not at all. I agree that it's a tool in the box and a very valuable one if used correctly or even just out of preference.

 

None the less, I've noticed a trend saying that you're not a "real photographer" if you don't use manual "all the time." Like I said, I use it as necessary or quite often out of necessity. If I really wanted thump my chest, I'd talk about how easy manual DSLR users have it with their fancy TTL meters and don't have to calculate filter factors, bellows factors, and all that other stuff that comes with non-small-format stuff. Then there's the fact that mechanically timed leaf shutters rarely run at their marked values :) . With LF and even on my RB67 lenses, I've taken to writing the actual shutter speeds on a slip of paper/sticker attached to the lens that I reference when making the exposure.

I use manual mode very often and that include manual focusing and manual exposure as well as not using the meter. However, I don't agree with the notion that you are not a real photographer if you don't use manual. I use manual simply because it's simpler and easier. It only takes a few seconds longer than auto and requires me to exercise my muscles a bit. So if I have a few seconds to spare I would use manual mode. Of course there are times I don't have even a second to spare.

Ordinarily I don't use compensation, and agree with several others here, preferring either to go to manual operation and disobey the meter, or to spot meter. Having used a D3200 for some time with manual lenses, I got pretty comfortable with no meter at all. But much of that depends on how leisurely the occasion is.

 

Recently on a trip to Botswana, where I was shooting hastily in different directions and did not always have time to adjust things, I found it handy to compensate. The light is bright and diffuse, the scenery often low in contrast. Lowering exposure in post cuts noise a bit, but if you are using aperture priority and a fixed ISO, compensation gets you a boost in shutter speed.

Hardly ever use compensation on my D700; if I find light conditions to be tricky, I prefer switch to manual over using exposure compensation. If light conditions are normal, I find expsoure to be typically fairly good with matrix metering (so I don't quite recognise the other findings with the D700 - mine is well-behaved). Plus, if the exposure is a bit off, it's well within reach of the raw editor to compensate later on.

When I'm photographing horse cross-country, I usually use Manual. However, I know I want f4 to blur out the background and 1/2000 th to 'freeze' the motion. I use Auto Iso to take up the natural variations. I shoot JPEG to sell on the day and RAW for on-line purchases later.

 

The compensation comes in when a particularly pale 'grey' or a very dark 'black' horse approaches. I know the usual centre-weighted metering can be a little over-zealous in it's views and I step in with + or - 0.3 EV. Very, very occasionally 0.7 is needed.

 

I could use just Manual, but the variations in weather/cloud cover AND horse tone together are too much for split second changes. I let the cam sort out the ambient and I sort out the horse correction.

 

There is only one take and I can't ask them to go around again 'cos I messed up!

Yes, when I use automatic exposure, I use exposure compensation with matrix metering. I rarely find I need to apply more than +-1/3 stops to get generally acceptable exposures in changing situations. Sometimes perhaps +2/3 stops in backlight. However if automatic exposure is way off, then I find it more conductive to set the camera to manual exposure rather than apply large compensation with automatic.
