A little girl was talking to her teacher about whales.

The teacher said it was physically impossible for a whale to swallow a human because even though it was a very large mammal its throat was very small.

The little girl stated that Jonah was swallowed by a whale.

Irritated, the teacher reiterated that a whale could not swallow a human; it was physically impossible.

The little girl said, “When I get to heaven I will ask Jonah”.

The teacher asked, “What if Jonah went to hell?”

The little girl replied, “Then you ask him “.

When photographers talk about the “depth of field” in an image, they’re referring to how much of the picture they choose to have in focus. You may think “but don’t I want all of my image to be in focus?” Frequently you do, but sometimes you can bring more attention to your subject by reducing the depth of field in a scene, making the background soft and blurry.

This image has very deep depth of field. Everything from the foreground to the horizon is in focus. You'll usually choose deep depth of field for landscape shots.

If you own a DSLR but aren’t experimenting with your aperture settings, you’re missing out on one of the most useful tools in a photographer’s arsenal. Here’s a primer to get you started.

BBC Radio 2 launched a stellar prank with news that at 9:47 a.m. on April 1, 1976, Pluto would pass behind Jupiter and that this alignment of the planets would result in a stronger gravitational pull from Jupiter, counteracting the Earth’s own gravity.
Listeners who timed a jump just at the right moment would be able to experience weightlessness, an astronomer in the report claimed.
Hundreds of listeners immediately reported that they had been suspended in mid-air (along with their disbelief).
One woman said that she and 11 friends — and the table they were seated around — had begun to float during the cosmic moment. Another caller said that the gravitational release had been so dramatic that she hit her head on the ceiling.

Whether you’ve got a DSLR or you’ve turned your point-and-shoot into a super camera, those fancy features are useless if you don’t understand them. Want to capture a perfectly exposed picture?
