A digicam lens hood is likely one of the most underrated photograph equipment. Many photograph lovers are sometimes fast to scoff at lens hoods, deeming them nothing greater than an pointless burden. I’m not of them.
I think about a digicam lens hood one of many important equipment in my digicam bag. I’ve lens hoods for each lens I personal, they usually hardly ever depart the lenses’ entrance components.
If you’re on the lookout for the reply to the query “What Does a Lens Hood Do?” this text is for you. By the top, you’ll clearly perceive how lens hoods profit my pictures and why you also needs to use them.
What’s a Digital camera Lens Hood?
A lens hood is a small, round accent that goes over your lens to decrease stray mild falling throughout the lens. And not using a lens hood, stray mild will trigger undesirable lens flares and a washed-out low-contrast look.
What Does a Digital camera Lens Hood Do?
There are 3 predominant capabilities of lens hoods.
1. Lowering Undesirable Stray Gentle
The primary good thing about utilizing a lens hood is to dam undesirable direct stray mild.
To higher perceive this operate, think about being exterior on a sunny day and looking out on the solar’s route. To enhance visibility, you instinctively convey the palm of your arm to your brow. Your palm casts a shadow over your eyes, and the image of the scene improves instantly. It turns into extra contrasted, clear, and vivid since you block the direct mild coming from the solar.
For the reason that human eye is a classy model of a digicam lens, the lens hood holds a operate much like your palm.

And when the reflective mild mixes up with the direct mild, most frequently coming from the solar, you expertise undesirable optical results. The results are lens flares, discount in distinction, and readability.
Use a lens hood when taking pictures outside. It can drastically scale back undesirable optical results.
And as a substitute of evaluating the scene and deciding if it has a possible for lens flares, it’s a lot easier to have a lens hood connected to your lens always. In distinction to lens filters, the lens hoods don’t scale back mild transmission, and it’s secure to maintain them at all times on.
However I have to admit that the digicam lens hood doesn’t at all times assist to eradicate lens flares.
Let me clarify.
Throughout the sunsets and sunrises, I usually shoot straight into the solar to extend the visible impact of the setting or rising solar. In such instances, even the lens hoods don’t stop undesirable lens flare. My resolution is double shielding. I take advantage of my hand’s palm to extend my lens’s shielding.
2. Bodily Lens Safety
Generally I feel that the bodily safety operate of lens hoods is extra important than optical safety.
If, for some purpose, I shouldn’t have a lens hood connected to my lens, I understand how to take care of lens flares or washed-out results. I can use the palm of my hand to protect undesirable mild. Or I can place my digicam within the shade of a tree or rock. However the bodily lens safety is unreplaceable.

One in all my favourite phrases that describe panorama pictures is “the worst climate produces the most effective images.” In sensible phrases, it implies that whenever you shoot within the rain or snow, you could wipe the entrance aspect of your lens each 15 seconds. Having a lens hood gives partial environmental safety. It’s important to clear your lens much less usually.
The environmental safety operate of the lens hood is the least vital one, however it’s nonetheless useful. It helps you to focus on taking pictures relatively than on cleansing actions.
