NASA Packs 17-Ton Telescope in a Boeing 747 to Solve Catch-22 of Astrophotography

sofia_landing_in_hamburg_6-28-14_0

NASA is known for using some impressive optics for its telescopes. But with amazing optics come some logistical limitations.

Ground-based lenses used by NASA can be as massive as needed, but are limited due to atmospheric distortion. Those used in space-based telescopes such as Hubble, on the other hand, must be much smaller, capable of being launched into space and fixed on-the-fly. This leaves NASA with a little Catch–22.

A Catch-22 they’ve managed to find an answer to in the form of SOFIA (Stratospheric Observatory for Infrared Astronomy): a Boeing 747 with a 17-ton telescope packed inside. Read more…

Diving Into the Tech Behind the Lytro Illum and Its Impressive 30-250mm f/2.0 Lens

Lytro_2

Lytro came into the photography world not only to create a novelty product, but to fundamentally change how we approach image capture. Because despite light field photography being around for over a century, it’s only with the latest technology that the company is able to exploit what it is a camera is truly capable of doing.

We recently spoke with Lytro about its upcoming Illum camera a bit, diving into the technology behind the specs and revealing how Lytro’s approach is allowing the company to not only step, but leap into the future. Read more…

New DxO Optics Pro 9.5 Features Complete Integration with Adobe Lightroom

DxOOpticsPro95_1

Up until now, when exporting a RAW image from Lightroom to another program to work on, Lightroom first had to convert it to a JPEG or TIFF image. This effectively rendered shooting in RAW useless if you were wanting to do much outside editing on the images. Here to change that though is DxO with Optics Pro 9.5. Read more…

Researchers Create Tiny, Inexpensive, High Quality Lenses by Baking Drops of Silicon

420392452215

Get out your Easy Bake Ovens and your polydimethylsiloxane, it’s time to make some lenses. Okay, okay… so it’s not that easy. But researchers at an Australian University have developed a new way to make extremely inexpensive, high-quality lenses by using nothing more than droplets of a transparent silicon and an oven to cure said droplets in.

Are Liquid Lenses The Next Big Thing in Photography?

Major camera makers including Olympus, Samsung and Sony have all filed patents in recent days for liquid lens technology. Unlike traditional glass lenses, liquid lenses don’t have any moving parts. Instead, liquid is used to focus light, and different voltages are applied to the liquid to change the shape of the liquid, thereby controlling the image. In the video above, techie Ben Krasnow introduces the technology, and then shows off a device he made by ripping a liquid lens out of a USB webcam.

Hoya Founder’s Grandson Calls Pentax Acquisition One Of Company “Failures”

According to  Hoya founder Shigeru Yamanaka’s grandson, Yutaka Yamanaka, Hoya’s acquisition of Pentax may not have been the best business move. The younger Yamanaka said the $1 billion acquisition in 2007 was made mostly to expand Hoya’s involvement in medical optics, but turned out to be “overpriced.” Yamanaka, a Hoya shareholder, went so far as to say it was one of Hoya’s business “failures” which led to financial turbulence over the last three years until Pentax turned profitable.

In spite of Yamanaka’s disapproval of the Pentax purchase, it’s rumored that other companies might be interested in buying up Hoya’s unwanted acquisition. Canon Rumors reports that Canon attempted to buy Pentax, perhaps in order to control more of the DSLR marketshare, in direct competition with Sony. Sony may also be interested in Pentax’s user base. But so far, no word on whether Hoya’s ready to hand off Pentax anytime soon.

PMA 2010: Glasses for Photographers

These glasses might look like typical geeky photo dad gear or something your eccentric uncle might wear, but if your eyes have uneven prescriptions, they can come in handy while shooting. That is, unless you’re classy enough to have a monocle (or contacts).

California-based photo accessory company, Hoodman, showed off this pair of glasses for photographers at PMA earlier this week. The glasses can be set with corrective lenses from an optometrist, and each lens can be individually flipped up. Corrections for the shooting eye can be adjusted with the camera’s diopter, remaining unhindered by an extra layer of glass, while the tracking eye can still benefit from corrective lenses.
