metering digital compared to film and slide film.

When metering for a digital exposure, I meter the brightest part of the scene. Then, I add a bit to the exposure. The added amount is determined by where I want to place that bright area. The bigger factor in the additional exposure is the characteristics of the camera and its ability to handle that additional exposure. That is determined by structured laboratory testing.

Use your camera meter and especially use the digital feature in the playback that 'blinks' for the over-exposure highlight warnings. Push your exposure to the right to the point of either:

a) you have some blinking highlights in non-critical aspects of the image or,

b) you see highlight warnings and you move the meter just back to the left until all blinking stops in your test image.

Then, compose, focus and shoot from there. The approach above is based on the 'all-over' metering option, Evaluative in Canon, Matrix in Nikon and similar.

So just average the exposure and trust the dynamic range of your sensor ? šŸ˜

Here's a quote. In case you missed it I'll post it again: "...with slide film it was best to under expose up to a stop."

In my over 40 years working as a professional in the photo industry I shot my share of transparency film. Doing studio product work I shot mostly Kodak Ektachrome. We bought the pro-grade film that came EI tested from Kodak -- you know the red stamp on the film insert -- and we tested it again (ran our own E6 line in house) because getting the exposure right with transparency film matters. Most of the work of course was done shooting strobes and we used Minolta flash meters to set the exposure but also tested with Polaroid film as a secondary verification. If any of us every said something so incredibly sloppy as just underexpose by up to a stop and your *ss is covered they'd be looking for work the next morning.

Why did you even ask your original question?

Given the kind of effort involved in setting up a shot like this, you don't just underexpose by up to a stop with transparency film. You get it right.
Here's a quote. In case you missed it I'll post it... (show quote)
I wasn't referring to table top photography I was referring to portrait photography. Not table top where you set it up and just bracket until you get what you like and the subject never complains about how long it takes or how how hot the lights are. You however are correct for that kind of shooting you need to be accurate with your exposure but that is not what I was talking about and I doubt you were using 35mm cameras and film for that kind of work.

And you made that really clear.

No, that was shot 4x5 sheet and you didn't just bracket until you got what you like -- that got you fired too.

I thought so. you bought a batch of film bulk tested the hell out of it calibrated your meters had an art director tell you how to set the shot up and when it came time to purchase a new batch of film the testing started all over again because film batch to batch varies. I bought my film in bulk, worked with my lab to get the best results that I wanted for the way I shoot just like you my point is some times you have to underexpose highlights to mateine detail in the shadows depends on what's important. I never said to underexpose for every shot only when it's called for.

How does, "with slide film it was best to under expose up to a stop" help maintain detail in the shadows?

That's not what you said. You made a generally applicable statement: "...with slide film it was best to under expose up to a stop."

I understand that screwing up and underexposing transparency film is better than screwing up and overexposing transparency film. I prefer not screwing up.

the key word is upto. not every time use your brain it is more intelligent that a meter. learn how to use the meter to get the results you want. learn your medium and equipment and use your brain.

Yes a critical medium like chromes should be exposed carefully. But donā€™t disparage the informal guidance to ā€œunder exposeā€ it slightly. The advice is correct for legions of users whose metering method is quite pedestrian and dare I say mindless. IOW that ā€œslight under exposureā€ ... in the hands of the simplest meter users ... most often results in the correct exposure rather than under exposure.


I agree. I always shot slides and always underexposed with great success. and I do the same with digital. Unless it is already a dark situation.

The key words are best and underexpose. Use your brain to do best and don't under or over anything.

thank you I agree with you 100% I never use the matrix meter in the camera as I don't like reflected readings. I never seen a person that was 18% gray. I always use my hand held incident meter and never less than 2 strobes. I'm not a landscape shooter and I never shoot Jpeg. I was well aware that film had more latitude than the paper that was used to print and shot accordingly and digital has more latitude than film which makes it better for post processing that's why I always shoot raw. I don't want the camera to decide how I want my image to look that's why I don't shoot Jpeg. I am a studio photographer and always shoot with strobes. Film is different than slide film and digital is different than them both but one thing that remains the same is light. Understand how to see and use light and you will always have a beautiful end result with little effort.

thank you for your answer but I must disagree with your comment about slide film. this is the way I was taught at Kodak and served me well for 40 years as a profession photographer.

At one workplace we didnā€™t have an in-house color lab. All of our 8x10 E6 was bracketed. Thereā€™s too many very small variables, and if they donā€™t vary all in divergent directions they can add up to +/- 1EV. So in order to SAFELY move on to the next setup or location, you MUST bracket 3 sheets.

We had 8x10 Polaroid, but that is also a variable. It was used for reviewing the details of the shot. It was not a reliable gauge of exposure.

Digital is ā€œmore likeā€ slide film. And digital is extremely harsh if you blow out the highlights, because you cantā€™ recover them.

I didn't say we didn't bracket. I said we didn't bracket until we got what we wanted. A standard 3 frame bracket for E-6 is common.
