How to Test Your Lens | B&H Explora


Saved by uncleflo on January 6th, 2019.

So, you just bought a shiny, new, and maybe expensive, lens for your camera, and being the savvy consumer, you did your homework. You pored over customer reviews on the B&H Photo website, read online reviews splattered all over the Internet, grabbed a copy of every photo magazine that reviewed the lens, bookmarked dozens of websites, and now have the lens’s MTF curve charts burned into your retinas. Now, your lens is here and it is time to go out shooting. Honestly, not a problem. Your lens should be as good as it can be and, as photographers, we want to take photos. So, stop reading and go out and make some photographs! Still here? OK, let me tell you why you might want to test that lens yourself. The main reason is that even with today's precision computer-controlled manufacturing techniques, there are variations in each and every lens that rolls off an assembly line. This means that some examples will be better than others. Some lenses will be outstanding and others will make you wonder if all of those glowing reviews you read online were completely bogus.

Lens Tests: A Simple Method


Saved by uncleflo on January 6th, 2019.

This is a simplified subjective method of testing lenses optical sharpness. This should not be confused with tests for focus accuracy and discrimination in a 3D environment, that is a totally different issue although often confused by the inexperienced. A focus accuracy test is suggested here Focus Test. The advantage over this method, compared to just taking a shot of a garden etc, is elimination of variables such as subject and camera movement, insufficient depth of field, flatness of field and variations in focus location. It uses a nice consistent high contrast subject to make comparisons easy; checking sharpness on general photographic views is not very easy. As the method is subjective, it is worth testing against a known good lens for comparison.

ISO 12233 — Resolution and spatial frequency responses | imatest


Saved by uncleflo on January 6th, 2019.

This new standard defines three test charts. The new Imatest eSFR ISO module performs a highly automated analysis of the new low contrast (4:1) Edge SFR chart and is available in Imatest Master and Image Sensor 4.0. This chart does not work with the highly automated Imatest eSFR ISO module, described below. For highly automated measurements (including squares near the corners, color patches, and wedges) we recommend one of the Imatest eSFR ISO charts shown below. These charts are fully compliant with ISO 12233:2017. Supported by the Imatest Star Chart module. Optional automatic region detection is available when used with a star pattern that has registration marks on the sides of the image.

When writing a ray tracer, sooner or later you’ll stumble on the problem of reflection and transmission. To visualize mirror-like objects, you need to reflect your viewing rays. To simulate a lens, you need refraction. While most people have heard of the law of reflection and Snell’s law, they often have difficulties with actually calculating the direction vectors of the reflected and refracted rays. In the following pages, exactly this problem will be addressed. As a bonus, some Fresnel equations will be added to the mix, so you can actually calculate how much light is reflected or transmitted (yes, it’s possible). At the end, you’ll have some usable formulas to use in your latest ray tracer.

Amazon.com: NEU SEX (9781576875568): Sasha Grey: Books


Saved by uncleflo on July 16th, 2014.

Sasha Grey, rising adult film and pop-culture star, takes control in her new monograph neü sex, moving out from in front of the camera to behind it, turning the lens on the wild world she inhabits. “When I first got into the adult industry, I decided to take my photography much more seriously. I started taking a camera with me to capture my experiences on set, so it was a moment in time, a memory for myself—not the video that would be seen by thousands of people. On days where I was physically unable to capture an image, Ian, my fiancé, became my third arm. He understands my aesthetic, or lack thereof. Ian is a photographer, yet the work in this book is quite different from his usual style. When you are so close with someone, there is a shorthand and true understanding of what the other person is trying to accomplish. If there’s something I am physically unable to photograph, I can say one word and Ian can assist me with my vision. Ian can capture intimate moments with me that nobody

Stereo Pair Photography


Saved by uncleflo on September 5th, 2012.

Stereo photography involves taking a photograph from two positions, these correspond to two "eye" positions. The two cameras cannot just be arbitrarily separated and point in roughly the right direction. The separation depends on the distance of the closest objects in the scene and the degree of stereo one wishes to achieve. The cameras should be angled inwards * so that imaginary rays projected into the scene intersect at a depth that is intended to be at the projection plane. Objects that are closer than this intersection point will appear to be closer to the viewer, points behind this intersection point will appear to be further from the viewer. There is a limit to how close objects can be made to appear and still provide comfortable viewing, a general rule of thumb is for the camera separation to be around 1/20'th of the distance where the camera rays intersect.

Loreo lens makes your Canon DSLR a 3D camera


Saved by uncleflo on December 21st, 2010.

If you like your Canon DSLR but are intrigued by the ability to take 3D pictures a new lens from Loreo called the Stereo Lens-in-a-cap promises to let you keep your cam and add 3D capability. Granted, the lens may well be the ugliest accessories that you well ever attach to your DSLR. The lens is cheap at $165 and has a pair of lenses that connect to your DSLR lens mount made into one device. It looks a lot like a point and shoot glued onto the front of a DSLR to me. When you press the shutter, you end up with one picture with two images in it.
