New Light Field Camera Can Focus Up-Close and Far Away Simultaneously
A new nanophotonic light field camera based on the eye of a Cambrian-era sea creature can combine macro and telephoto magnification into one lens with unlimited depth of field.

Macro photography works well with conventional lenses and inexpensive extension tubes. The combination achieves 0.3x to 0.5x magnification. Depth of field is much greater with these moderate magnifications than at the 1x magnification possible with macro lenses.
Recently, the more I study my photographs, the more I feel that bokeh is cheating me out of a more substantial image. I really like photographs with a lot of visual complexity -- well presented, not chaotic, but a clear arrangement of multiple elements.
We all know that reducing aperture increases depth of field, but how much does that help? Here are some facts about depth of field.
The folks over at YouTube channel Media Division recently put together an incredibly comprehensive test of the fastest camera lenses on the market. In this video, they cover everything from the legendary Zeiss R-Biotar 100mm f/0.73 X-Ray lens, to some of the more "practical" options with maximum apertures under f/1.
A Japanese patent from Sony hints at a future lens that would allow you to shoot first, and focus your photos later. By combining multiple smaller lenses into a single larger lens, the idea could open up a world of new imaging possibilities if it ever comes to pass.
Photographer Felix Jäger recently got to review a lens that many Micro Four Thirds shooters have on their wishlist: the Voigtländer 42.5mm f/0.95. But while that mouth-watering aperture number might set your heart to racing, don't whip out your wallet just yet.
Photographer Usman Dawood of Sonder Creative recently teamed up with film photographer Adam French to put together an intriguing portrait comparison: high-resolution full-frame digital vs 4x5 large format film. They shot both cameras at about the same FF equivalent focal length, and then compared the resulting images side by side for your viewing pleasure.
Given how much more it costs to buy an f/1.4 prime compared to an f/1.8, beginners in particular often ask if the upgrade is worth it. Build quality and optical quality being equal, is the difference in light gathering capability and depth of field noticeable? Can you really tell?
In this video, I’m going to put to rest this question once and for all: does sensor size affect depth of field? I’ll be physically taking pictures with a full-frame camera and a Micro 4/3 camera, and showing you the visual difference in a range of aperture settings. There are lots of theories and opinions on this but here is the definitive answer.
When you purchase a new camera, how much time do you spend reading the manual? I find most camera manuals rather difficult to follow along with, and I for one very rarely use them. What’s interesting is that camera manuals only describe the technical “how to” side of things, like how to turn on your camera or how to attach a lens, but it doesn’t tell you how to truly become comfortable with your camera.
If you have a fast and expensive lens, it may feel like a waste to shoot portraits stopped down to f/8, f/11, or f/16. But in this 20-minute video, photographer Miguel Quiles explains why he often opts to shoot stopped down instead of wide open for increased depth of field and finer details and textures.
By carefully applying blur to a portrait, you can make it look like it was shot with a shallow depth-of-field using a fast (and expensive) lens. Here's a 12-minute tutorial by PiXimperfect that teaches the key to creating this faux blur in a realistic way.
Along with the announcement of Nikon’s new mirrorless Z-system was the development announcement of a 58mm f/0.95 Noct lens. The Z-mount’s huge inner diameter of 55mm (the F-mount has a 44mm diameter) means more light collection capability, which enables ridiculously fast lens design. Nikon’s F-mount 58mm offering tops out at f/1.4.
First launched in the iPhone 7 Plus, Apple's 'Portrait Mode' uses depth data from dual rear cameras to generate faux blur for a shallow depth-of-field effect. Google's new Pixel 2 has a similar mode that's done with a single "dual pixel" sensor. Now Samsung has unveiled a new "dual pixel" sensor that may bring this tech to an even wider audience.
Focus stacking is a technique typically used in macro shots to achieve a large depth of field. It’s a relatively simple concept: take many images focused at slightly different distances and combine the sharp portions to a single image in post. This 6-minute video from landscape photographer Mark Denney will show you how to utilise the technique in landscape photography.
The progression that is the discovery and appreciation of photography is a journey unique to the voyager. Whether the path is walked through a textbook, an online forum, or alone, there is no two that are alike.
In this 20-minute tutorial by PiXimperfect, learn how to use Photoshop to create a realistic bokeh effect in your photo. Creating a shallow depth of field after you've taken the shot can be tricky to do convincingly, but this tutorial will show you one method for how to do it.
DSLR cameras often have a little depth of field preview button beside the lens mount. This 3-minute video by ZY Productions revisits the basics of a DSLR camera and looks at how this handy button works, as well as some lesser-known things to consider.
There is a lot of misunderstanding and confusion on the subjects of depth of field, the difference between full-frame and crop sensors, and the ‘crop factor.’
