Dogwood blooms along the Merced river shoreline.

Highlight warnings or Blinkies as some photographers call it are life savers while photographing Dogwoods. When enabled, this feature tells the photographer if a particular section of the photograph has been overexposed and does not have any details within it. They show up as annoying little red patches blinking as long as you are previwing the image. They are annoying at times and that is a pretty good reason not to anable this feature.

But you see, the naked eye looking at the little 3″ screen for instant feedback, is not that good at identifying overexposure. We see the picture as a whole and not in parts. As a whole the there is a tendency for us to believe that the shadow details and colors ( in this photograph, the green foliage) need to look much more appealing. If we go ahead and compensate our exposure to achieve this goal, then the result will defniteley be an overexposed highlights. This is where the blinkies come into picture.

They help you see individual areas that are lacking in detail. With that information, the photographer can make a concious decision to either leave those blinkies there, knowing fully that the overexposure is not a problem, or compensate the exposure to remove them.

In this photograph, compared to the entire frame, the individual dogwoods are very small and (also very bright compared to the surrounding foliage) hence without the blinkies, its hard to determine if we’ve captured good details in them. Well, you may ask, does it matter if as small section of the frame is overexposed? The answer depends on the presentation method, if we only plan to use it for online posts, then, may be not. But if we do plan to make big prints, then yes, it matters to pay attention to each and every small detail in the frame.

In my last post, I talked about how the dogwoods shine against the background forest when the light is just right. This shot is one such case. Bright diffused sunlight shining through clouds gives some even lighting to the scene. Even with this even lighting, I used a polarizer to removed some distracting reflections off of the dark foliage surrounding the dogwoods.

Scenes like this are abound during the peak dogwood blooming season, but isolating them from the surrounding forest and finding a spot to place my tripod was sometimes easy, but sometimes required good amount of bush whacking :)
