The second article in an occasional series aimed at beginners called “Things Experts Forgot to Tell You” or “Things that You Forgot you had to Learn” was All about Exposure. (The first article is Why Won’t My Lens Focus?) This post expands on the ideas presented in that article with some real life examples of exposure problems and how to overcome them.
I currently back from a trip to the Pacific Northwest and Alaska. One of the principal publicity problems that I encountered was white, featureless skies due the fog, mist, and overcast clouds not unusual within the area. There are a few special options for dealing with this sort of problem, and I will present a few examples to provide an explanation for them each, beneath.
AE Lock
In All about Exposure I explained some of the benefits of the AE Lock button and how you can use it to override your camera’s suggestions about what the correct exposure might be for a given situation. I found myself using the AE Lock button quite frequently at Mount Rainier to force the camera to balance the darker colors and tones of the trees, rocks, and landscape against the overwhelming brightness of the overcast skies.
The pics above display the impact of the use of AE Lock. The photograph at the left became the digital camera?S proposal for the ideal exposure, based totally on evaluative metering: ISO one hundred (set by using me), an aperture of f/5.6, and a shutter velocity of1/eightieth. For the photograph on the proper, I pointed the digital camera up at the nearly clean sky, pressed the AE Lock button, and then recomposed the photo, which ended in an exposure of ISO 100, an aperture of f/8, and a shutter velocity of 1/one hundred and sixtieth. The 2d photograph is deliberately underexposed, according to the digital camera, but a long way higher represented the colours and tones earlier than me, in my view. It also delivered more definition and detail to the sky.
The brightness of the sky can effect an picture even when you don?T think about the sky as being within the photograph, as in the snap shots above. Here, the brightness of the sky is clear within the light filtering thru the trees and the shadows on the course. The digital camera chose the publicity on the left: ISO one hundred (set via me), an aperture of f/three.5, and a shutter pace of one/13th, even as I used the AE Lock (once more, pointed up more toward the sky then recomposed) for an aperture of f/three.5 and a shutter speed of one/twentieth. This mild underexposure led to higher hues and intensity to the general photograph (as did slightly adjusting the composition to ensure a straight horizon line and vertical trees).
Recompose
Another option to repair publicity troubles is to rethink the composition of your picture. If a featureless sky bureaucracy too large of a part of your photograph, it is able to be not possible to nicely balance it out for a effectively exposed photo.

In the image above, I desired to attention at the tunnel, however while I become happy with the colours and info via and in the tunnel itself, the sky above got ?Blown out.? (Blown out is a term that photographers use while a photograph or location of a picture becomes so overexposed that it will become absolutely white and loses any detail that might have been there.) If I used AE Lock and exposed for the sky, the resulting darker image would lose the colours and details in and through the tunnel that I wanted.

The answer right here turned into to reconsider after which recompose the image. I knew that I desired to characteristic the tunnel, both inside and outside, so I determined to recompose the picture to completely exclude the sky. Then it became a lot less complicated to stability the mild and tones earlier than, interior, and thru the tunnel.
Bracketing
The method and ‘how to’ part of exposure bracketing was covered in the All about Exposure article. Bracketing is a particularly useful technique in the field when you are unsure about an exposure or want to capture a range of different exposure options.
I recognize that the LED display at the again of my digicam is merely a compressed photo and no longer a superbly accurate representation of the picture that I have captured. In general, I actually have discovered that pics that I may suppose appearance ?Too darkish? On the LED screen appearance perfectly uncovered when I download and have a look at at them on my laptop display. The LED display is also difficult to peer in brilliant daylight, and I regularly don?T reflect onconsideration on how my carrying shades while looking at it can impact how I interpret an photo. Thus, once I find myself in a situation in which it is tough to decide the perfect exposure, I frequently depend on bracketing and make the selection later, in the front of my pc.
For a lot of our time at Rainier, we had been unable to peer the mountain itself, due to the fog, mist, and clouds, however I nonetheless desired to seize images of the bits of the mountains that had been visible. Determining the publicity become hard, because of the brightness of the sky, the darkness of the trees, and the variable nature of the mountain, so I determined to apply exposure bracketing.

This set of 3 pictures, bracketed at plus-and-minus one forestall at the publicity reimbursement scale, demonstrate more than a few exposures for the same photo. In this situation, I appreciated the definition of the mountain and the blue sky inside the middle picture (underexposed), although it rendered the encompassing pine bushes as pretty darkish and a bit featureless.
Fixing Exposure Problems for your Photography
The key to locating and fixing exposure issues in the subject is understanding what you are trying to accomplish in every image and the usage of workaround strategies, as wished, to satisfy your purpose. If a vivid sky or overcast day is making your images appear too brilliant or blown out, use AE Lock to take a reading from the sky, recompose your image, and spot if you get a end result this is toward your liking. Or, if you could, exchange the composition of your image to exclude the sky totally and get rid of it as a factor. Or, provide your self a buffer by means of the use of publicity bracketing to seize a range of different exposures for the equal composition and pick the satisfactory at a later date. Each of these strategies offers you greater manage over your photographs and their publicity and could assist you come home with the snap shots you desire.
