One of the most appealing things about the whole Job-o-sphere, is that software (in the form of apps) is profitable for developers and affordable for customers [while making Apple into the biggest software provider in the history of the universe – Ed]. KitGuru ponders how much apps should cost and is there a limit on pricing – beyond which only a mad man would go?

Photographers love the light. Their waking hours are spent imagining the capture of photons as they bounce of flowers, mountains and ladies. It's a bit of an obsession.

While it is possible to shoot in a studio or other location with a flash, its the thermonuclear light in the sky that gets them most excited – especially when you can take that sun light early in the morning/late in the day and filter it through a few million tons of water vapour.

Which brings us to ‘the question'…  Where will the sun be, at a given time of day and specific point on the planet?

Photographers (and other interested parties) can find out by spending £21 on an App called Helios Sun Positioning Calculator from the ‘all all Brits plus an Aussie' development team called Chemical Wedding – based in Los Angeles.

Toby Evetts does agency-level brainwashing for clients like Nike and Disney, Simon Reeves used to be a banker (with a ‘B') and Nic Sadler is a bit of a photo buff in his spare time. Together, they have driven this company forward with a series of clever applications, including:-

TOLAND: Digital version of the American Cinematographic Manual

ARTEMIS: App that gives you the Director's Viewfinder on a phone

CYCLOPEDIA: Uses geo-info, linked to more than 65,000 Wikipedia articles, to give you ‘articles' that are relevant within a 30 mile radius of your physical location (but you can adjust this down to around 1 mile)

Which brings us back to the ‘Where is the sun dude?' app. While cool, we're not sure how many people will be pulling out 21 Great British pound coins – but maybe the chemical bros are happy with only selling to the cognoscenti.

KitGuru says: If you need it, you need it – but we can't help thinking that a lower price would generate a big increase in unit sales. For us, most apps should be under £10.
