Understanding Correct Exposure

In this video, the speaker talks about getting a correct exposure and explains what it means. They then demonstrate how to set an exposure of a scene in manual mode and discuss the three options for setting an exposure: shutter speed, aperture, and ISO.

What is Correct Exposure?

• An exposure is taking a picture with settings that make it look the way you want.

• A correct exposure doesn't necessarily have to look the same as what your eyes are seeing but should be what you want.

Setting an Exposure in Manual Mode

• Demonstrates how to set an exposure of a scene in manual mode.

• Discusses the three options for setting an exposure: shutter speed, aperture, and ISO.

• Shutter speed is the length of time that your shutter remains open when you take a picture.

• Aperture is the size of the opening of the lens expressed in fractions. The smaller the number, the larger your opening.

• ISO is the sensitivity of the sensor. The larger the number, the more sensitive that sensor is.

Live View as a Learning Tool

• Live view can be used as a great learning tool to see what exposure would be obtained with current settings.

Adjusting Camera Settings for Correct Exposure

In this section, the speaker discusses how to adjust camera settings to achieve a correct exposure.

Shutter Speed and Negative Effects

• A slower shutter speed can be used without negative effects when taking pictures of still objects.

• The general rule of thumb is that your shutter speed should be a bit higher than your focal length.

• If you have a lens with IS, you can go a little bit slower.

Adjusting Aperture and ISO Sensitivity

• Increasing aperture decreases the size of your lens opening and vice versa.

• Increasing ISO sensitivity makes the sensor more sensitive to light and vice versa.

• Adjusting these settings can help achieve a correct exposure.

Choosing Shutter Speed for Moving Objects

In this section, the speaker discusses how to choose an appropriate shutter speed when taking pictures of moving objects.

Shutter Speed Rule of Thumb

• Your shutter speed should be above your focal length when holding the camera steady.

• With a lens that has IS, you can go a little bit slower.

Choosing Shutter Speed for Moving Objects

• For moving objects like people or animals, use a shutter speed around 100 - 125th of a second.

• You may need to adjust other settings like aperture and ISO sensitivity to achieve correct exposure.

Balancing Aperture and Exposure

In this section, the speaker discusses how to balance aperture and exposure when adjusting camera settings.

Adjusting Aperture and ISO Sensitivity for Correct Exposure

• Increasing aperture allows more light into the camera but decreases depth of field.

• Decreasing aperture allows less light into the camera but increases depth of field.

• Adjusting ISO sensitivity affects image noise.

Achieving Correct Exposure

• Adjusting aperture and ISO sensitivity can help achieve a correct exposure.

• You may need to adjust other settings like shutter speed to achieve correct exposure.

Adjusting Camera Settings for Better Exposure

In this section, the speaker talks about how to adjust camera settings to get better exposure in photos.

Starting with Aperture

• Start by adjusting the aperture to control the amount of light entering the camera.

• Use AV mode to set the aperture and let the camera automatically set the shutter speed.

• Adjust ISO based on the resulting shutter speed.

Avoiding Auto ISO

• The speaker is not a fan of auto ISO as it gives more control to the camera, which can lead to bad decisions.

• Learning how different settings affect image quality is important.

Factors Affecting Image Quality

• The speaker mentions factors such as avoiding motion blur and handshake, choosing an appropriate aperture for the scene, and setting ISO below 1600 for entry-level DSLRs.

• If necessary, increase ISO to avoid blurry images even if it means slightly noisy photos.

Conclusion

• The speaker concludes by thanking viewers for watching and promising more videos on related topics.
