Live histograms.. (Page 4): But it does cost you some loss of DR and some additional noise - how much depends on how much you underexpose.

I always slightly underexpose. I find it easier to bring up the dark than reduce the light.
Just a bit...nothing heavy handed.

Just a bit...and with a good sensor...you'll never notice it.
Add in Topaz denoise ...which frankly is ... amazing...no worries.

Other recent threads have discussed this. One idea is to set the camera to as low as possible in terms of picture quality settings and to get the white balance correct in camera or use uniWB which my camera doesn't have. Others have demonstrated that the individual color histogram is really quite close to raw.

Good video, worth watching to the info about white balance at the end.

For the raw histograms it's nearly always the green channel unless the lighting is unusual like after dark or in artificial light.

Or you photograph a lot of highly saturated flowers.

You can set UniWB on your camera if you want. You need a lazy afternoon and a little time. There are multiple methods.

I agree with Linda. My Olympus can display a live histogram.

Depends on how much you underexpose and what ISO you’re at. If you’re shooting at base or low ISOs, you may not see the difference, but as you move down in light and up in ISO, one stop underexposure can cost you a stop of DR when you only have 4-5 to work with or double the noise. Fixing it in post may reduce the noise (with some effects), but you can’t replace the DR. Underexposing in low light/high ISO situations is just throwing away performance that you paid for. Not a great practice unless you’re worried about inaccurate metering and blowing highlights.

Understood...why I do it just a bit.
it's easier to raise the dark areas, than lower clipped highlights.
Once the detail is gone...that's all she wrote.

Can the Nikon D7200 display a live histogram? I tried to follow the video for the full frame, but I did not find the histogram on my crop sensor D7200.

In the case of any live-view histogram being viewed before the photo is taken (there is no JPEG yet) the histogram is derived from the live video feed. If the camera is a mirrorless camera and effort has been made by the engineers to match the live EVF image to the JPEG that will be created then the live-view histogram is a fair representation of what to expect in the JPEG. I'm not aware of any option from any camera maker that presents a live-view histogram designed to represent the raw file.

We cannot be more wrong. When a camera uses a live view it can produce a 'live' histogram and display it. This is rarely implemented thought.

The Nikon D750 offers a live view histogram.

I'm pretty sure my Fujifilm X-100T and my Pentax K-3 can also do that. What specific functions with live view and active histogram I have not investigated.

My X100T only shows a luminance histogram or highlight warnings after the shot. Nothing live and no color histograms.

Yes and no. Most top of the line cameras (all manufacturers) seems to have it* the other?

What I cam to realize is that to find the settings for it is awkward to say the least.

My Nikon D500 goes nuts when it is set with a live view histogram with P mode. It is likely due to the changes in settings when the camera is moved or if the light changes. I any other mode there is no issue. I will have to check if the D850 does the same 'waltz'.

This is a private message sent by Bob and concerns the Nikon D500 and D850.

It may work for your camera if not many others.

1 Press the Live View Button
2 Press the Info button (grid appears)
3 Press OK (Exposure Scale appears at the right)
4 Press the Info button (histogram appears)

Do thank Bob for the info, not me.

This is an outdated assumption. Some cameras, e.g., from Olympus, have included live histogram for years. Good to hear that Nikon is playing catchup with an already well established technology.
