What is your normal exposure metering method?
2

With the advent of Analog Front Ends on Sigma cameras with the consequent danger of blown highlights, even at high ISO settings compared to earlier models, what is your normal method? This question is more about such as DP2x, SD15, Quattro but I'm interested in any Foveon-equipped model. It is also about single-shot photography: not stacking and not SFD - trying to keep to basics ...

Personally, I spot-meter the area of interest in the scene and make my best guess at the necessary exposure compensation. If that blows some brights or blacks out some shadows, so be it.

Is there another way? That's how I meter in M mode.

With my SD Quattro I use the liveview histogram to balance the exposure as best as I can. I know it's for jpegs but as I use the camera regularly I know what I'm going to get based on what the histogram is telling me, it works well for me. I also do the same with my DPXM's, I normally leave all of them in matrix metering mode. For those that might say the histogram is not particularly accurate, I never get an exposure I'm not happy with using this method, first time. I rarely have to change the exposure at all in post, unless I've deliberately under-exposed with a view to tweaking it in post.

Depends entirely on subject, light and intention.

Metering in the last generation of film SLRs and in today's better digital offerings is so sophisticated that I see no merit in "I always shoot manual" unless using only an external meter.

I use A or S  depending on whether depth of field or camera/subject movement is an issue, and if in doubt bracket the exposure ..........

The same here.

Also M mode when using non-TTL flash.

Re: What is your normal exposure metering method?

Greetings

I use 4 different metering methods depending on what I'm shooting

1. Spot meter and bracket 3 shots -3 right on +3

2. Spot meter splitting the highlights and shadows in the exposure circle

3  Hand held light meter

4 Meter off my hand and open up 1/2 to 1 stop.

Have fun

Re: What is your normal exposure metering method?

I don't meter, except that I see the preview of the exposure and the live histogram in the viewfinder and on the rear screen, when shooting with my EVF cameras Ted. By those I just estimate what I will need the exposure to be, based on what I'm seeing in the viewfinder. (i.e. are there bright spots of sunlight on an otherwise shaded subject? If so, I feel that in order to avoid blown spots in the shot, I'll normally reduce exposure a little, by setting the shutter speed one or two clicks higher/faster. If things are too dark, and I need to expose more, I'll just slow down the shutter speed or step up from ISO 100 to ISO 200, and then adjust the shutter speed, if I feel it's necessary. I don't spot meter. Instead I guestimate, and then chimp.

I always shoot manual, because the camera might suddenly change the exposure, based on some light suddenly peeking through the leaves, and coming from the subject, or maybe my subject moves, and more light comes from the background. My camera, left on any auto setting, might reduce exposure just at the wrong time. Imagine if I had used an auto-exposure setting with this photo?

It would have been over-exposed or under-exposed.

Even this one probably would have turned out under-exposed:

I shoot aperture mode 99% of the time.  I used the histogram more to avoid overexposure than under and I frequently bracket 3-5 shots with a tendency to go lower rather than higher on exposure.  Blown highlights are my greatest fear.

I'm glad you were joking Scott!

Otherwise, I'd have to ask you to explain exactly how this histogram of your posted review image is inaccurate:

Especially when ImageJ's histogram of your original image is almost identical (see bottom right):

And, with only a bit of noise in the dark area selected at top right, I'm not sure why you called the image "noisy"! To me, a SNR of about 50 in such a dark area is pretty good - SPP must have been quite busy, LOL.

Maybe the words „not accurate“ are not really correct in a semantic or literal way here. Maybe „not representing the RAW data“ would be better in this respect. As far as I understand, the histogram shows the distribution of brightness from the resulting in-camera jpg. I accept that some people use the words „not accurate“ in this context based on the assumption that they do the RAW development in SPP and not with the actual settings in-camera.

I think this is a good example. Do you really think that the two histograms are almost identical? But maybe the imageJ histogram uses a different y scaling. And you show the histogram in SPP, not the in-camera histogram. I didn‘t test it, but I assume the SPP histogram already reflects the settings in SPP, not what you see in-camera.

The thing is, if you're using a jpeg histogram in camera, and you position it as you see fit, you know you will always have more latitude when it comes to processing the raw. The trick is to understand where the distribution of brightness is on the histogram and how to use that information to give you the exposure you are aiming for. People have a tendency to over-complicate this, but it's really quite simple in practice,

A RAW histogram, whilst undoubtedly still useful, has less utility with Foveon because of the extreme 3x3 colour matrices. The current in-camera histogram used as you say is logical and most practical.

@Ted, with my SD1M I shoot Manual and spot-meter significant areas of the scene, taking an exposure decision from there. With my DP3M I use intelligent ETTR via the histogram. I AEB everything because... well why not
