In photography, the idea of depth of field, or the portion of a photograph that is in focus, isn't an easy one to grasp. Like almost everything else in the photographic world, it is possible to figure out what the depth of field of a given (or even hypothetical) photograph based on the size of the film or imaging sensor, focal length, aperture, and the distance to your subject. Given the number of factors involved though, the math gets a little complicated. Thankfully, the folks at ExpoImaging have created the ExpoAperture2 Depth of Field Guide to figure it all … Read more
Not only does it have substandard resolution and "all the standard functions you'd expect to find on a crappy knock-off," as put delicately by OhGizmo, but it also looks ridiculous too. As much as we understand the practical desire to combine portable functions, we've never heard of a calculator being among the most pressing needs.
Perhaps most disturbing of all is that it's … Read more
If you have ever wondered just how much to tip your server after a restaurant meal, this iPhone app is for you. Simply enter the total cost, use a five-star rating system to rate your service, then select the number of people (if you're splitting the cost).

Believe it or not, there are some retro gadgets that are even too old for us. So we must seize on them while we can, because soon the only machines that will fall into this category will be from the Industrial Revolution.
Enter the HP 35s calculator, a new version of the original HP-35 (note the hyphen) released in 1972, which is being trotted out from the rest home for its 35th birthday. The seminal gadget has been updated to include "ample memory for keystroke programming, equation solving and more than 800 storage registers; 100 built-in functions; and a … Read more

Tip calculators are pretty common in most cell phones, but unfortunately the iPhone only has a regular ol' calculator (Which you can also use to calculate tip, but that's beside the point). Danny Goodman has developed this neat little tip calculator for the iPhone--enter in the number of diners, the total, tax, and it'll calculate the tip for you, plus the total amount of money each diner needs to pay up. I really liked that with each tap of an empty field, a large number keypad pops up, making it easy to enter in the numbers.

Ever wonder if you are worth more dead or alive?
Someone dating you might, according to the dating site Mingle2.
While Mingle2's cadaver calculator won't do life insurance policies or tell you your carbon footprint, it will tell you how much your healthy body, or unhealthy body as the case may be, is worth to science.
If you don't mind anonymously answering personal questions such as the number of drinks you have in a week or whether you have elephantiasis, the bizarre quiz will calculate your worth in death.
Unfortunately, good health and normalcy is not necessarily … Read more
It's taken decades, but it all makes sense now.
When we were kids, TI calculators seemed as common as No. 2 pencils, but they were used basically as extensions of multiplication tables and other rote learning. Now, Texas Instruments claims to have finally made the leap into the interactive future with the "TI-Navigator."
This handheld device lets students send their work instantly and wirelessly to teachers' computers in the classroom. Not only can instructors review answers in real time, but they can also analyze student thought processes as they observe the keys being punched to "understand … Read more
As if this pink and white crystal-encrusted optical mouse weren't bad enough, it's offered with a calculator in the same ill-advised motif. Uber-Review suggests this ensemble as a possible gift for Mother's Day. We'd agree only if you had a miserable childhood.
The wood look is definitely in. It's one thing to see sylvan casings for computers, TVs, cameras and even iPod cases, but it's officially a trend now that it's worked its way down to the lowly calculator. Like its recently featured wooden laptop tote, MoMA says the calculator is made from "ecologically thinned Japanese cedar," according to Uncrate. And if you environmentalists out there are concerned about felling trees, you can at least take some comfort in the fact that it's powered by solar energy.
