Today in Cheap Photo, we’ve found a new deal on the Canon 5D Mk II with up to $625 in savings at $3,289. But there are also still Sony A7 discounts, lens discounts, and mirrorless camera rebates in place.
The idea of 4K video lenses sounds a bit crazy, doesn’t it? With modern lens design being so incredibly good and able to resolve loads and loads of detail, why does it matter? Canon developed a video explaining the science behind these lenses in a very interesting way.
Canon’s video breaks it down into four different components and talks about things like lens coatings, contrast, MTF, and resolution. According to the video, the lenses have to be able to resolve a 9MP image of some sort–which pretty much every lens released since 2009 is very capable of doing since that’s when the megapixel war took a very big leap with the release of the Canon 5D Mk II’s 21MP full frame sensor and Sony’s A900 24MP full frame sensor. But if lenses are too sharp, then they create moire (in conjunction with the sensor) and other issues.
What’s really cool is how they explain light loss when beams of light pass through elements on a lens and how coatings helps minimize light loss. The animated video on Canon’s 4K Video Lenses is after the jump.
What food image are you most likely to purchase if you were a restaurateur or had to market food in some way or another? Shutterstock recently tried to find out what that trend is. Despite the internet’s love and affinity of bacon, that isn’t necessarily what sells.
The study divides each type of food photo into a specific category. So what sells images?
– Rustic looks
– Farm produce
– Mason jars
– Blueberries
– Smoothies
– Vegan food
– Butcher produce
– Sausages
But then the study continues to break it down into even more specifics. For example the JAckfruit and durians are amongst the most sought after images of fruits and veggies. Minas and Quinoa are most sought after for grains, ribeye the most sought after meat, mochi the most sought after sweet, and lots more. It’s a very interesting study that you should totally check out. But in order to make those food images look better, we’ve talked to more photographers about how to get better compositions and better food images overall.
If you ask most photographers in Istanbul about where you can find a good darkroom, they’ll tell you to talk to Taylan Bağcı. He’s got a darkroom on the second floor of a nondescript building on a side street in the Tophane (Tohp-ha-neh) neighborhood. It takes a bit of navigational know-how and perhaps a Turkish friend or two to help you find it, but once you do, you’ll find yourself in a space dedicated to film photography.

We’ve added more sample photos to our Sigma 150-600mm f5-6.3 DG OS HSM Sport Lens first impressions post. So far though, we tested it more for portraiture than sports, but we’re going to do so! With a flash, this lens shows off nothing else but pure sharpness, and even without a flash in good lighting. The image stabilization is proving to be quite effective, but man is this thing heavy.
Low Key Lighting, notice the shadows
What is High Key and Low Key lighting? The folks over at Adorama TV try to explain it to you in under three minutes. Dan in the video after the jump explains that high key lighting is when your lighting is very low contrast with almost no visible shadows. This is done often in portraiture and is very forgiving.
In comparison, low key lighting has very high contrast. It can make a subject really pop in a scene.
Dan’s video is after the jump, but we’ve added extra examples of High Key and Low key lighting after the jump.
