.Take a test shot of the scene/subject you want to photograph, then look at it on your LCD. Observe how many blinkies there are, and what part of the scene is blinking. Then note whether there are a lot of little tiny areas blinking, or if there are big massive areas blinking.

You might also take test shots with each camera to test the accuracy of the blinkie function. My G15 produces "false positive" blinkies. Some blinking areas are data-free, as intended. On the computer screen, they'll be pure white. Other blinking areas will be almost completely blank but not quite. With my simple PP program, the proof that they contain data is that using the eyedropper tool on them moves the Temperature and Tint sliders.

This might be the time to mention that there is an accurate exposure which is technically correct, but it may not be the correct exposure in the sense that you are not obligated to be limited by where those tones might fall on the gray scale. The real trick is learning how to make the technically correct exposure, and the wisdom to know when to chuck that out the window.

I've been confused by that exposure compensation thing because the histogram was all over the place when imported into LR.

Since starting to shoot in manual mode, utilizing Live View's histogram, those problems are a thing of the past. Technique is:

That LV histogram is based on a jpeg rendition of your image so you need to "neutralize" (slide them to the left) all your "picture style" settings.

Set-up your LV to display a RGB histogram and blinkies whenever it's opened. Now it's a simple matter to adjust SS, F/stop, and ISO to

"push" that histogram to just shy of the right side, a technique referred to as "Exposing To The Right".

Now simply input wanted/needed SS and f/stop and use the ISO to push that histogram to the right or...any combination of the three settings.


The things you do for yourself die with you, the things you do for others live forever.

Starts with right technique but ends with right taste.

Chauncey, reading another post that appeared a couple of hours ago I think I may have found an explanation of your point.

Is it this?

What you have to understand is that when you are shooting jpegs, the image and the in-camera preview and histogram are rendered using the Picture Style setting for that jpeg, including Contrast, Saturation, and Sharpening.

What is not-so-obvious is that if you are shooting Raw, the Histogram is also derived from those in-camera Picture Style settings.

So, those of us who shoot Raw typically dial our Picture Style settings for Contrast and Saturation all the way back so we don't get "misleading" readings from the Histogram as well as Highlight "blinkies", although there is still "range" in this stuff, but we do what we can!!

Thanks Tony. When you say "dial back" do you mean to "zero" or to the "minus" number for each picture style? I assume you mean zero but just wanted to check

I mean, if you are shooting Raw, dialing back the Picture Style settings for Contrast and Saturation and Sharpening to "-4" will produce a more accurate histogram and "blinkies", especially if you set your Picture Style to Neutral or Faithful.

Having Contrast or Saturation even set to "0" can be misleading! You can see this by using DPP as a reference!!

lots and lots of practice and studying your pictures and being in all types of different lighting situations. I can usually estimate my exposure pretty accurately before i even start shooting
