(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 ?
How far apart are an object and an image formed by a 79 cm focal length converging lens if the image is 3.75 times larger than the object and is real?How far apart are an object and an image formed by a 93 cm focal length converging...
After the camera, atelephoto lensis an excellent place to start. If you only want to capture close-ups of the moon, a 200mm or 300mm lens can be a pretty solid investment, and getting one with an even largerfocal length— such as 400mm — can make for even more detailed work. Grab...
Take a Good Photo of the Moon with Your Phone Phone cameras often have a wide lens and a small sensor, so the Moon might come out looking like a blurry dot of light in the sky. But there is a new generation of phones that let you take better pictures of the Moon. Here is how yo...
The focal length, or the size ofsecurity camera lenses, is the NO.1 factor determining how far security cameras can see. It is measured in mm and can be classified into fixed focal length (found infixed lens security cameras) and variable focal length (available amongvari-focal IP cameras)...
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 ...
Answer to: How far (in mm) from the lens must the film in a camera be, if the lens has a 33.0 mm focal length and is being used to photograph a...
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 ...
Remember, you may have to put a flag in front of the camera. The flag will block the lens but up and towards the camera is going to work. So let’s get back to that, up and towards the camera, right there. So now what we’re going to do is we’re going to put a fill card...
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...
