How to avoid underexposure or overexposure when shooting with SLR camera?

1 to avoid underexposure or overexposure.

Most SLR cameras have histograms that can be displayed in your camera. The leftmost part of the histogram is all black, the middle part is gray and the rightmost part is all white. If most pixels are concentrated on the left side, it is probably underexposed. On the contrary, if the pixels are concentrated on the right, it may be overexposed, which is very easy to see. Therefore, if the naked eye can't tell the exposure problem, learn to look at the histogram.

2. Avoid losing the bright spot.

Overrendering is a common thing in SLR shooting, which will directly lead to the loss of details. The best way is to reduce the exposure shooting of 1-2, and then pull it back through Photoshop later, which can effectively preserve the details. Of course, be sure to save it in RAW format.

3. Get the correct exposure when shooting the silhouette.

It is much easier than you think to capture a person's silhouette before a beautiful sunrise or sunset. Just aim the camera at the bright sky, choose aperture priority, set the size to about f/ 1 1, and select photometry to evaluate photometry. If the subject is too small, you may need to set exposure compensation and increase some exposure, otherwise, if the subject is too big, you can reduce some exposure.

Tips for shooting SLR cameras:

1, set automatic white balance.

When the light changes, it is recommended that you set the SLR to automatic white balance to ensure perfect color balance.

2. Reduce the noise caused by long exposure.

Long exposure will cause some noise to the photos, especially in the blue channel, which is the most serious in the RGB channel. In order to solve this problem, you can take pictures in RAW format, denoise them through Lightroom or Photoshop, and restore the clarity of the pictures.

3. Relax the use of automatic ISO.

Automatic ISO in SLR is a magical function, which can ensure that ISO is high enough and shutter speed is fast enough to avoid camera shake affecting photography. Before that, it is usually set to the default ISO to get the lowest shutter speed. This means that the minimum shutter speed can be set to1125 if a 50mm lens is used.

4. Learn specific metering skills.

Exposure is particularly important in some landscape photography. In many SLR cameras, when shooting in spot metering mode, the camera will measure the light from the active focus. If you shoot a landscape without ND grad filter and want to expose the sky to preserve the details, you only need to set the SLR to manual focus, set the active point in the sky, select spot metering, and then use exposure compensation for fine adjustment.

5. Choose the measurement method

In SLR photography, the correct exposure can be obtained by choosing the correct metering mode. Generally speaking, when there is a good contrast between light and dark in the scene, it is a good choice to choose evaluation photometry because it can balance the exposure well. Central metering is the most ideal when using ND grad filter to shoot landscapes. For backlit objects, spot metering helps to avoid underexposure.
