Title: Yet another BusPirate v3.something free PCB build
Post by: erdabyz on October 29, 2011, 02:26:19 am
This one has been a present for a good friend of mine.

Picture:

As always, it's soldered with solder paste and reflow and has some manual touches with the iron. It works perfectly.

It was left as a soldering exercise for its new owner ;P. It should no longer be missing.

Great soldering indeed. Also I liked the minimum burn due to camera flash. Did you used external light? Or flash diffuser?

I guess the angle did the trick. Flash burns will occur when you photograph without or a small angle.

I prefer to use naturual lighting (daylight) or a light box for this kind of photography.

Yep, the angle did the trick. It's one ot the few things I know about photography and it was learnt the hard way. I'd prefer to use natural sunlight but... it's kinda hard to see it these days even in the centre of Spain...

Looks like I have to learn that trick too to use flash safely for indoor macro pictures. When I need to take picture of some PCB at good colors and obviously burnless, I wait till noon, then take pictures in sunlight with ISO-80 and 1/30 exposure without flash to get best results.

practise a lot :)

depending on the camera, ramp up the ISO to get a better (faster) shutterspeed. Also play with the aperture (although you want to have a high aperture to get more things into focus) and use a tripod/beanbag to stabilize the camera (use the timer feature to prevent vibration during button press).

I guess this needs a seperate topic as we are moving a bit offtopic ;)
