Theoretically, in a vacuum there's no limit to how far away your eyes could see since light rays can travel an infinite distance, McCulley says. But on Earth's surface, "you're seeing through the atmosphere, and yellow particular matter in the air is scattering the light," he says. "...
Its focal length changes between 5.8–17.4mm, which is a ratio of 1:3.An ordinary lens has a fixed focal length—so it does one job and one job only. But what if you want it to magnify a little bit more or focus on something slightly nearer or further away? Our own eyes (and ...
The handheld light meter is an extremely powerful accessory that was far more popular in the days of 35mm photography. But this versatile and precise tool is just as valuable when shooting with modern digital cameras, and this tutorial explains why, when, and how. Continue Reading » Pages...
Without a camera lens, your camera body could not capture images. And it's important to choose the right lens because it helps you reach your camera's greatest potential.
(II) (a) How far from a 75.0-mm-focal-length lens must an object be placed if its image is to be magnified 2.50 x and be real? (b) What if the image is to be virtual and magnified 2.50 x ? Verified step by step guidance ...
The S.3 spotting scope is heavy at 60 oz considering it has a 67 mm objective lens, but it’s still around the same weight as some of the most high-end spotters with the interchangeable eyepiece system. Tripod mount it and you’re set. It’s not like you’re hiking with it as it...
Yes, I guess a RAW workflow would be better suited to landscape photography. The reason I've avoided working with RAW software so far (other than X-RAW) is the Fujifilm simulations. No third party software exactly nails them. I can't say that I'm especially enamored of the in-camera ...
Edge-sharpness is generally better than in the cheaper Canon RF 15-30mm f/4.5-6.3 IS STM but worse at 24mm, whereas the 15-30mm hangs onto center-sharpness better in the longer half of the zoom range. I found that the Canon RF 14-35mm f/4L IS USM L-series lens gives better ...
this is a pretty advanced technical procedure with innumerable adjustments, because it can calibrate a lens to behave differently whether focusing near or far, and at multiple focal lengths throughout a zoom range. However, this is usually a bit overkill, and it is also something that we do ...
you need to consider keenly where you stand. The fisheye lens will introduce a lot of space between you and the subject, hence you must consider how close or far away you are from the subject so that the pieces of the compositional puzzle will fall in place smoothly both in the horizontal...
