If a scene is too bright, what’s the best way to reduce exposure? Should I use a smaller aperture, a faster shutter speed, or something else? Also, what can I do if I want to keep a specific depth of field or shutter speed for creative reasons?

Exposure is essentially controlled by Aperture, Shutter speed and ISO. You need to balance these to get correct exposure. Assuming you are shooting manual (M on the left top dial).
The delicate balance between aperture, speed and iso depends on the image you are trying to capture. I usually ask myself questions before taking a picture.
- Do i need to isolate subject from background?
- Do i need to include background in the picture?
- Do i care about about background?
If i can answer the above questions then it fixes aperture for me.
- Do i need to capture motion?
- Is subject moving and i want to freeze action?
This fixes speed for me.
Once one of speed and aperture is fixed then look at your light meter. Change the other till the meter indicates correct exposure. There are limitations to be considered. Like you don't want speed to be very low etc. And then ISO comes into picture. A stop change in one these cuts light by half or increases twice.

Exposure is controlled by three settings: aperture, shutter speed, and ISO. To reduce too much light, you can:
- use a smaller aperture (higher f-number)
- use a faster shutter speed
- lower ISO to the camera’s minimum setting
Which one is best depends on the photo you want.
- Aperture affects depth of field, so choose it based on whether you want background blur or more of the scene in focus.
- Shutter speed affects motion, so choose it based on whether you want to freeze action or allow blur.
- ISO should usually be kept as low as possible in bright light.
A common approach is to decide your creative priority first: set the aperture you want for depth of field, or the shutter speed you want for motion, then adjust the other setting until exposure is correct.
If you can’t change aperture or shutter speed because of artistic goals—such as wanting a wide aperture in bright sun or a long exposure for smooth water—use a neutral density (ND) filter. An ND filter reduces the amount of light entering the lens without changing color, letting you keep your preferred settings.
