Cats’ ears are very sensitive to noise(s) of all kinds.

In this episode of our series on the Basics of Photography, we’re going to talk about a topic that isn’t very popular, but that almost every photographer has to deal with from time to time: noise. Or, more specifically, image noise of the kind that appears in digital photographs under certain circumstances. In this article, we’re going to look at the different kinds of digital image noise, the specific circumstances under which it appears, and how to get rid of it without compromising the overall quality of the final image.

Chris Gampat The Phoblographer Zeiss 50mm f2.8 Touit product photos (1 of 7)ISO 4001-60 sec at f - 2.8

Back around late last year, we took a very early look at the Zeiss 50mm f2.8 Macro Touit lens for Sony E mount and Fujifilm X mount cameras. We’re happy to say that the new 50mm f2.8 Touit lens is right now in the house and we’re currently underway with testing it. As the company’s third offering for the lens mounts and their first macro lens, it is also the company’s longest focal length. Rendering a 75mm field of view due to the APS-C sized sensors, the lens can double as a portrait optic as well as be used by anyone that just wants some glorious bokeh due to the way that the field of view and aperture work out.

With a full frame equivalent of f4.5 on a full frame camera, this lens is also by all means not small–but nor is it small on image quality.

Screen-Shot-2014-04-20-at-12.08.04-pm

American alternative band Red Jumpsuit Apparatus couldn’t have handled a copyright infringement any worse than if they had defecated on Sydney-based photographer Rohan Anderson’s backyard themselves.

The whole ordeal started with a single square filtered image. Sometime yesterday, RJA posted a photo on their Facebook, which immediately acquired likes in the hundreds. This photo was shot taken by Anderson in Sydney in 2013 during an RJA show.

Anderson admits in his blog post about the drama that it’s not uncommon for bands he’s photographed to use his photos without permission; but he points out that he usually lets those go because they give him credit and thank him for it. Unfortunately this time around, not only did RJA completely forgot to give him credit for the photo in question, they also cropped the original image (and thus removing his watermark) and added some sort of photo filter. To add insult to injury, the photo’s quality was greatly reduced.

This, of course, hit a nerve, as it would any artist whose work has been altered and used without permission. So Anderson emailed the band, informing them of the copyright violation and asking them to either take the image down or pay for its use.

Lytro Illum

Two years ago Lytro introduced a camera that promised to change photography forever using a light-field sensor to let shooters take a picture and then change the focus afterwards. Its first camera was little more than a webcam in a baton but today the company is doing things over with a higher-resolution camera in a much more familiar hybrid-styled body.

Meet the Illum–it’s Lytro’s monstrously large new camera aimed at creative pioneers. It’s equipped with a new “40 megaray” that does more than shoot square photos. On paper the Illum is a big step up from the original Lytro camera’s 11-megaray images, however, the Illum still only manages to eke out a four-megapixel shot once all the focus points are flattened out.

Lytro has also improved the optics by giving the Illum an 8x optical zoom range lens with a constant f2.0 aperture. The lens is integrated with the camera and features a strange tire tread pattern but it provides a wide focal length range going from an equivalent 30mm to 250mm. Another bit of unique (or weird) design is the angled 4-inch back LCD that slopes down. Luckily the screen it comes attached to an articulating arm so the camera is good for more than shooting photos below eye-level.

On top of all the new body, Lytro says it has revamped its Light Field Engine to a 2.0 spec. The new engine help users compose their photos by display a visual representation of the focus range right alongside the regular histogram. The Illum also has a form of focus peaking that highlights objects in focus with green outlines.

The camera is a beast and it comes with an equally large $1,599 price tag. Early adopters will be able to pick up the camera starting July 2014 for a special introductory price of $1,499. We’ll have to get this camera in for ourselves to try before we can say this camera is the real deal. Until then check past the break for more images and specs on the Lytro Illum.

Lens and Shutter has recently created a number of products that can be hung up on the walls of every photographer or any place just looking for a way to spruce up their apartments. They feature famous sayings in the photo community along with cute cartoonish renderings of cameras. They come in a slew of different colors and all feature different cameras and photographic items like TLRs, rangefinders, SLRs, and film. We can totally see these emblazoned on a T-shirt or some sort.

They’re totally worth the look if you’re in the market for some extra flair.

Samyang 35mm f1.4 for Canon with electronic contacts

Samyang, the South Korean company whose lenses are sold under the Rokinon brand name in the US, have recently teased a new product announcement for April 28th. Thanks to a video report from the Photo & Imaging Show that has been held in Seoul over Easter, we now have a pretty good idea of what is going to be announced that day.

Besides two new cine lenses, Samyang will very likely announce a new 35mm f1.4 for Canon EF-mount which, for the first time, will sport electronic contacts that allow the use of auto-exposure modes such as program and shutter priority mode. The two other lenses that Samyang is said to announce are a cine version of the 7.5mm f3.5 fisheye lens for Micro Four Thirds, sporting a T3.8 speed rating, as well as a cine version of the recently announced 12mm f2 lens for APS-C mirrorless systems.

Unfortunately, despite many customers asking for it, Samyang will not introduce any autofocus lenses soon, according to an interview with the website DicaHub. This is mainly due to licensing issues, but also the amount of information available on each camera system’s AF. Our guess is that the major player such as Canon and Nikon won’t just give away for free all the secrets of how their respective AF systems work.

Considering the lenses mentioned above have been shown off at the P&I show recently, it is safe to assume that they’ll be officially announced soon. Whether or not one or all of these will be announced next Monday, April the 28th, remains to be seen. Stay tuned!
