Strobist Lighting102 on Flickr - 2013

If this is in the wrong place please move.

I'm doing this series of lighting exercises. I'm hoping some of you will join in. Images can be shared on flickr in the discussion group and threads.

Posting on here, just to encourage folks to join in. This is an excellent way to gain a significant amount of knowledge for how to control the flash gear you have to get the results you want.

I'm not sure what the point of this exercise is but I see several things that you need to address when doing a lighting exercise intended to learn how to use speedlites.

A) keep track of the power settings at each distance between the subject and the light source. Distance is one of the variables that affect the hitting the subject.

B) Have the zoom setting on the speedlite appropriate to the lens being used. Canon speedlites, when set to auto zoom tighten the light cone to improve efficiency. The logic is that light falling outside the lens angle of view is wasted.

C) It is useful to use distance measurements between the subject and the light source that correspond to F stop numbers. This helps to confirm the validity of the inverse square law. And while not perfect does provide a useful guide. i.e. 2.8 Ft., 4 Ft., 5.6 Ft, etc. In a perfect world moving the light that far will result in a one stop change in light being delivered to the subject at the same power setting and zoom.

Good luck with your experiments and practice.

It's a 5-month series with a few dozen lighting exercises that increase in complexity over time.

It starts new each January. Hereis the latest series of posted exercises. All from the Strobist.com site.

You start with one flash, simple shots in a circle around a fixed object, and work your way up from there. Results of the exercises are posted/shared.

This forum always has people jumping in to the deep end for lighting without first learning the basics.

I was/am hoping that some of the hundreds of folks that hang out here on a daily basis will be inspired to join in.

I wouldn't bet on anything so outrageous as folks actually learning how to do something from the bottom upwards. The trend now seems to be:

• Throw a credit card about and try to buy a solution. As if that ever works! (But it does keep the industry going).
  
• Devote countless hours searching for a gadget or 'App' which will do the job for them.
  
• Demand an "Auto" button so both brain cells can have a rest simultaneously.
  

I just don't think there's that much of an audience here at that specific level..

I'd say 50-60% of the people on the forum never come over to the lighting area.. and probably 75% of the people that do come the lighting forum would consider the inverse square law second nature, and not something that really needs to be practiced.

Of that remaining 25%, probably half are still trying to figure out why there's black lines in their photos.

Just not a whole lot of people at that particular skill level, IMO.

Good luck, I like your diagram, and that cat!
