Up early as usual... Damn brain thinking. Its 8:40PM now, thought I'd better complete a blog for today. No point in ruining it now.

Didn't do much this morning. It's mother's day. Went to Mum and Dad's with Kel and had a barbecue. The other thing I did while over there was sort some of the crap that I have at their house. I have heaps. Computer and Electronics parts mainly. Anyway, I brought home some PC power supplies and other bits.

One of the power supplies I will be using in a project of mine that is in the works. A set of 2 maybe 3 halogen lights on "Helping Hand" arms. These will be mounted on a bracket then mounted on the bottom of my camera. Running from the bracket will be cables. At the end of the cables will be a box. This box will contain one, maybe two SLA batteries for portable use. The AT power supply will also be in this box. It will have two purposes. One. Charge the SLAs. Two. Run the lights from AC power. A PC power supply is perfect for halogens. It has a 12V rail that can run into 10s of Amps. Perfect.

This light or lights will be used for macro photography. It’s difficult to get the depth of field that you want in low-light in macro photography because the f/ stop is so low (bigger hole). If the f/stop is higher (smaller hole) the depth of field is increased. To use a higher f/stop there needs to be more light.

So, if the subject is better lit I can a) possibly hand-hold shots with a shallow depth of field because the shutter speed required will be faster. Or b) get a better depth of field by using a higher f/stop on a tripod! I hope that all makes sense. It’s bed time!
