Greetings from the edge of... something...

Hi everyone. Well I had hoped to be much more productive this last week but I have been unwell and away from work and generally not doing too much at all, including all things photography related. It’s been a bit of a bummer but what can you do…

Anyway, tonight’s blog post is a continuation on the theme of studio test shots and the resulting images that I have posted on my Project 325 Album on our Facebook Page.

As you can see from the image, this time I was going for something very low-key as far as the lighting was concerned; but I still wanted to be able to clearly see the black object against the black background (even though the backdrop is actually a white paper seamless roll) with plenty of definition and edge detail.

Those of you with a keen eye will notice that the lighting diagram is almost identical as the last one I posted with one very important exception. With the last example we had a very high key backdrop by filling it with reflected light created by placing a strobe with a bounce umbrella on each corner of the backdrop and bouncing off it; this time those two backdrop lights have been turned around and have gridded reflectors on them to basically eliminate any spill whatsoever. Those lights are aimed directly at the back of the subject. The key light (beauty dish, also with a grid attachment on it) is metered for ISO100 @ f/8, with the accent or ‘rim lights’ metered at f/5.6.

So, even though I was shooting with a white backdrop, because there is no light spilling onto it we have achieved the effect of turning it black. Cool. Just be careful of lens flare in this set-up though. You can see a little bit of it in this image, but in this instance I don't think it is too obtrusive. If it gets too bad or you wish to eliminate it altogether from your shots you will need to flag off the rim lights from hitting your lens - more on this soon.

Of course you will not quite get the same effect when shooting a model because (in a full length shot) you will see some light hitting the floor and therefore lighting the backdrop around their feet. But for anything less than full length; i.e. do not get the floor into the shot, for all intents and purposes the backdrop is totally black.

Ok, starting to feel dodgy again (too much information?!) so I’ll stop there. See you all soon.
