The Camera’s LCD.                

Of all the modern technology conveniently packed into our DSLRs there is one major trap DSLR users should be aware of when attempting to find a correct exposure. And that, in my opinion, is relying on the camera’s LCD.

That little picture screen will lead you astray faster than believing a politician’s promises. It should never to be trusted.

This past week I talked to two different photographers that were wondering why their photos were improperly exposed when they downloaded them into their computer. However, when they handed me their cameras in hopes I would correct some programing error I immediately saw their problem.

The LCD is great for previewing and checking for closed eyes and composition, but it’s never completely trustworthy, and committing the following three transgressions are a sure way to give yourself an unpleasant surprise when you download your images for processing.

I’ll begin with the LCD’s Brightness. If you leave your camera on auto it will change the brightness based on ambient lighting and that can be confusing when one reviews images.

I suggest setting the LCD’s brightness manually for a more reliable way to judge the image. Some photographers even change it for different events so they know exactly how their image is meant to look for different ambient light levels. However, for most of us, a static setting will be just fine. Whatever brightness we our LCD to, it’s going to be better than auto.

My next thought goes to the Histogram. Even with the LCD set to manual brightness, many still only rely on that JPEG preview without paying attention to, in my opinion, one of the best features on digital cameras; The Histogram. The histogram gives a mathematical bar graph representation of the image’s tones. It is also a quick and easy indicator of an under or over exposed capture. And most importantly when the graph shows clipping on the far right or far left, that the photograph is losing detail.

Reading the histogram may be a bit daunting at first, but it’s just a simple bar graph and with a little research and practice reading the histogram will become second nature.

And finally the Highlight alerts. Highlight alerts are a flashing overlay that can be set up to alert when there are clipped highlights. This means that some areas of the photograph are to bright and have no detail recorded at all. The flashing areas on the LCD that many affectionately call, “blinkies” show us where the detail is missing.

It is important to remember that what we are looking at is, in fact, a JPEG preview and hopefully you are shooting raw and won’t actually lose that all that data when opening the image to post-process. However, if a large portion of the image is flashing your camera is alerting you that much of the data may not be recoverable.

If the subject is a bride and her white gown is flashing on the camera’s LCD, you’re in trouble and need to dial back your exposure or face a very angry bride when she sees her expensive gown is reduced to a wash of pure white.

Every camera should come with an instruction manual. The Instruction Manual is one of the most important accessories you have with your camera. And if the camera was purchased second hand it is very easy to find the instruction manual on line. The instruction manual will help you understand and control the three important LCD features I have dicussed.

  2. Thanks you for this valuable info John. I’ve never used the Histogram b/c I felt it was too techy to bother with. But now I will certainly check it out. I never shoot RAW b/c I’m happy enough with JPEG, can edit most images to my liking, and don’t need tons of extra memory. Don’t always need everything in the image to be full of tonal detail – except for some classic Portrature or Scenic shots.

    • Glad you found my article useful. And yes, you should learn to use the Histogram.
      Regarding JPG vs RAW, The JPG limited data is hard to edit. You loose so much colour information when editing. RAW is so blasted forgiving and much, much easier (and quicker) to edit. But you must have a program that will covert that RAW data.
      Once you start Shooting and editing in RAW you will wonder why you ever thought JPG was good.
