Iso shutter and f stop

Aperture — This is the hole that lets light into the camera, meaning controlling how wide or how small this hole is determines how exposed or bright your image is going to be.

T he size of the aperture is measured in f-stops, and, the lower the number of f-stop a lens is able to reach, the wider the hole will be and the more light it can let in. The aperture is controlled within the lens. ISO — This is adjusting the actual digital reading and letting the camera know what the sensor can sense. When filming, try and only use ISO , , , Bracketing was a technique that was popularized from shooting slide film, due to the limited ability to correct the image in the darkroom.

Many photographers still use the technique today, so they have the exposure that they want. Having the three bracketed images lowers the amount of post-processing time that they might have to spend. Simply put, overexposure is when the information in the highlights is effectively unreadable.

Underexposure is pretty much the same concept; except in this case there is no image information contained within the shadows. This non-existent information cannot be retrieved through post processing either. This is not always the case in the photochemical world of film photography. In this mode, no matter what changes there are to the lighting in the scene, the camera locks in the ISO, Shutter, and Aperture settings, so you can continually achieve the same EV without having to re-meter the scene.

You want to become increasingly proficient with all three elements of the exposure triangle so that you can make adjustments on the fly and know exactly what the resulting effect is going to be. As it is, we have many more options, most lenses have an aperture range that lets you adjust the aperture size one-third stop at a time, hence all the in-between options.

Tip: Remember, the bigger the bottom number, the narrower the aperture. A smaller bottom number of the f ratio signifies a larger aperture. If you change a setting by a full stop one direction, you can always compensate by changing another setting on the exposure triangle a full stop in the opposite direction or both of the other settings by a half stop each. Tip: Mirrorless camera users have an added bonus when they shoot in manual mode. They can see in real-time the effects that changing their aperture diameter makes and adjust the other exposure settings simply by looking at the screen.

Halving or doubling ISO numbers will also halve or double the image exposure. A shortcut is simply to count how many clicks you move.

For example, if you adjust your aperture dial three clicks darker, compensate by moving your shutter speed dial three clicks brighter. And so on. For example, most portrait photographers favor a shallow DOF to better isolate the subject from the background.

Both the foreground and background are blurred. This f-stop setting creates a super shallow depth of field. Both the foreground and background are nicely blurred, while the subject is nicely in focus. Putting F-stops, shutter speeds and ISO together for creative control Now that we understand f-stops, shutter speeds and ISO settings, we need to manipulate them to improve our photos.
