Is 4K the Future of Photography?
By Justin Miller (Zenfolio Technical Evangelist)
Today we have a new standard of video resolution. It’s called 4K. That means 4096 x 2060 pixels. That means: quite a step up from your momma’s television set.
This higher-than-normal resolution has a couple of implications to the average consumer. It’s not a broadcasting standard. It needs an expensive high-res TV or monitor, and it requires a serious computer to play games in 4K with a reasonable refresh rate. But what does it mean to a photographer?
For photo editing, it means a sharper image on your screen. If you’re shooting with a Canon 5D Mark III camera, the maximum resolution on any photo is 5760 x 3840. A Panasonic Lumix DMC-GH4 will give you 4608 x 3456. This will require a lot of memory cards that can record quickly and reliably. Then, if you want to view any of those photos on a monitor at 100 percent, you’ll need something that can handle that resolution. 4K gets pretty close to the resolution listed by those cameras, and you can get a camera that can do this for under a grand as long as you have a computer with a video card that can handle it. A more recent MacBook Pro can handle 4K through the Thunderbolt port, although your refresh rate might be somewhere between 15 to 30 Hz. But if clarity is what you want, check out the 27-inch iMac with a Retina 5K display. That’s an amazing 5120 x 2880 resolution. It all boils down to this: if you want to shoot 4K, you need the proper equipment to capture, store, and edit it.
The flip side is what video can do for you as a photographer. Previous HD video often meant 720 x 1280. More recently it’s been a standard 1920 x 1080, the same resolution as most monitors. Today you can get a GH4 for less than $1500 that records video 24fps at the same resolution as still images. That’s more than 4K. The GoPro HERO4 for less than $500 shoots at ultra high definition 3840 x 2160. This all translates into the ability to pull some amazing shots from frames of video. Previously you couldn’t use video frames because lower resolution wouldn’t be high enough quality. 4K changes all of that. Why miss a second when any one of those 24 frames could be photographic gold! Talk about a new crazy culling workflow.
4K isn’t a necessity. In some cases it’s just plain overkill. I’d never call 4K a game changer for photography and won’t be running out to get my hands on a camera or monitor that can handle it quite yet. The technology is improving and prices are going down. However, 2015 might be the year for 4K.

I really believe 4k it's the "next" future but I do not believe video will "still" market from professional photographers.
Video and Photo use different techniques. It's not the same to get a photo from a video frame than do it properly with a camera.
Video "means" movement and the settings need to be different. The shooting speed, white balance, etc are different from the ones we use in photography.
How can you pull the same photo if I can photograph and get nice clear and in focus photos as fast as 1/8000s?
At the most it can be used as a "emergency image", but I would never give my clients photos pulled from video frames unless I missed the bride entrance or the rings, but thats why I always have an assistant to back me up.
For a photographer who has a business photographing their clients, flixel is probably not the final form. More likely it's print. However, I do look forward to see how flixel changes the market and video becomes the future. Until then, the immediate future doesn't require any camera upgrades.
4K hybrid photography is very hot right now. Many of the stunning cinemagraph images being uploaded to flixel.com are now be created from video shot on 4K cameras. The real question is "Is video the future of photography." We think it is. Rather than trying to grab that perfect shot - simply shoot video and extract the perfect still. So much easier and the results can be spectacular. Take a look at the gallery of user-created cinemagraphs at http://www.flixel.com/cinemagraphs
4K is the newest, latest and greatest thing happening in the digital screen world. CES was just here in Vegas and the 4K TV's were in full effect. I personally don't think it will have a huge impact in the immediate future. TV sales will be what drives 4k to mainstream, and it is easier (and cheaper) for companies to broadcast 720p. Although 5 years or so from now, 4k will be everywhere.
