what is iso in photography ???????
(please explain).
Mainly when you are doing something in macro photography (say with a micrometer screw) or if you want to get close to infinity, where the image curve is really long … ??????? the maximum visible light intensity after digital conversion in your camera will be a smaller area of highlights, i.e. you have to lower the ISO. This can bring unwanted noise and blur, so it’s better to take some time for practice with that kind of images and gain skills in that…Be patient, try this with ISO 50 or 1600 so see all effects: Quick unsharpness aka digital noise averaging, max brightness from middle but start disappearing towards blacks, sharp lens IR cut off etc …. ———— I agree, what’s up with \This is a short movie about what is iso in photography.

Why use shallow depth of field for pet photography?

With the depth-of-field being so shallow, whatever troubles you about the background can melt into a beautiful creamy bokeh.

What is the aperture of a lens?

The aperture is the window in the lens that controls how much light does (or doesn’t) hit your sensor. The aperture mimics how the eye works. On a lens, the aperture is denoted with f-stop. If you look at a lens, you’ll first see the focal length (the millimeter number) followed immediately by the f-number.

How does the aperture work?

On a lens, the aperture is denoted with f-stop. If you look at a lens, you’ll first see the focal length (the millimeter number) followed immediately by the f-number. This number tells you the widest point that the aperture can go.

Why use shallow depth of field?

The shallow depth of field allows you to mask the flaws. If you’re photographing dog sports, such as canine agility, you’ll find that the background is very distracting with all of the different colorful obstacles. This is a great opportunity to use a very shallow depth of field to take an eye-catching photograph.

What does a wider aperture mean?

With a wider aperture comes other types of effects too. Wide apertures cause a shallow depth of field. The depth of field expresses how much of the image is in focus. Shallow depths of field mean that less in the frame is in focus. For example, a dog is in focus but the background blurs away.

How does aperture affect light?

Aperture affects the light intake of your lens. The wider the aperture, the more light comes in. The narrower the aperture, the less light comes in. Pair this with an ISO and shutter speed setting and that dictates how bright or dark your photograph will come out.

Why is shallow depth of field important?

This is because photographs taken with a large aperture allow all of the focus to lie on the subject. The background ceases to remain a distraction. Finally, shallow depth of field can create dreamy, ethereal, or soft photographs.
