Using a low-cost IKEA spotlight for studio effect

Posted on By

IKEA has a very low cost optical focusing theatre-style spotlight which can be used, or adapted, for studio work. It comes complete with an adjustable iris diaphragm unit, a four-blade square aperture adjustable unit, a gobo/filter holder, a set of stainless steel cut gobos and a set of coloured glass filters. The focusing lens is not sealed against light leaks but open to allow heat to dissipate, however if this unit was adapted to hold a flash light source in place of its halogen bulb, you could also make a tube to seal off the light leaks from the optical assembly.

Sony Alpha 200 – guided tour and overview

Posted on By

The Sony DSLR A200 is now on sale, following the end of Alpha 100 production. Although it is without any doubt the Alpha 100 replacement mentioned by Sony executives in October 2007, when they first revealed that the 100 was no longer being made, it is not an exact equivalent and represents a mixture of upgraded performance and simplified specification.

However, it’s handling Alpha 700 raw quite well. And it does things differently, with non-destructive raw editing, stacks of image versions, and so on. Continue reading »

An amazing 360 degree panorama

Posted on By

Daniel Oi is a dedicated and experienced Alpha system user currently staying in Glasgow. He’s created a particularly impressive 360 degree panorama of a tiny area of the city centre which has unexpected magic in its Christmas lighting garb. Go down Buchanan Street, turn towards George Square, and you will walk through this Georgian enclave with street cafés, galleries, bookstore, museum and an atmosphere quite unlike the busy main drag or the vast square it links.
