Help create CB pocket reference Swag for LDI!

Basic rule down one side, both metric and imperial

 

[Pie4Weebl]

I don't think phone numbers would be too useful. Likewise, how to match cam colors shouldn't be on there.

How about a little chart of size of pools lights make at different distances, so I could quickly look and see, well I'm shooting at 50' so this 19 degree will give me "x"

Going off zmb's post, common fixtures gel cut and gobo sizes. Another thing to that probably won't make the cut for the size, but I feel like saying anyway is the resistor color code.

Along with that, the PRG cable length code.

PRG cable length code.

which is?

How about the approximate field angles for instruments described by their lens diameter and the focal length.
EX,
4.5x6 ≈ 50°
6x9 ≈ 36°
6x12 ≈ 26°
6x16 ≈ 19°
6x22 ≈ 10°

I added a poll to the top of this to help us figure out which measurement marks would be most useful. Please vote for two, as that will help us decide the most useful combination. Remember this is a credit card so it's only 3" long.

 

[Morydd]

Slightly crazy, but combine the color wheel with the color codes. So an arrow to green that shows (note, I'm making up the numbers so they're most likely all wrong):
PRG-50'
Res-5ohm
Wire-Ground
etc.

 

[carllib]

What about including the Electric Formulas Wheel and the USITT Lighting Symbols?

If you are going to have a metric, PLEASE millimetre mark it. When you only have 75 odd mm you're only measuring small things and so accuracy becomes of some importance

 

[dvsDave]

Millimeters are tough. There are 25.4 millimeters in an inch and the printer prints at 300dpi. 300/25.4 = 11.8 oh yay. Do I accept the rounding error and make it a 11 pixel space between each 1 pixel-wide center mark (11+mark=12), would that level of accuracy be okay?

 

[cpf]

Just as long as the error does not accumulate. If you're looking closely enough to discern a 84um discrepancy, you shouldn't be using a swag giveaway to do the measuring...

It's theater.

And I agree to include the electrical formula wheel.

I've done the maths - it's in a spreadsheet I just emailed you since one is not permitted to upload an xls...

Basically some gaps will be 11px and some will 10px...

 

[dvsDave]

Dude, you rock. You just saved me a ton of time! I'll get this inputted today.

 

[gafftaper]

Again I want to point out that Chris lives in Australia and it's tomorrow there. He is able to get so much done around CB because he lives in the future.

Chris can you check on some lottery number results for me?

 

[JChenault]

I'd like to second the idea of a chart showing throw distance to beam spread.

 

[LavaASU]

Ditto. I'm always looking that up and/or guessing (do I need a 19 or a 26?!?)...

 

[derekleffew]

Which would be preferable,

a) a LIST of the multiplication factors:

90 degree= 1.88
70 degree= 1.40
50 degree= .93
36 degree= .65
26 degree= .46
19 degree= .31
10 degree= .178
05 degree = .119

OR

b) a CHART of angles and distances:

(from Lighting Designers Page ) [With better formatting. And valid data--ignore the rubbish constant of .018 on the page referenced--it's been disproven elsewhere. The correct method to calculate is to use the formula Beam diameter = distance * (2 * tan (beam angle in degrees / 2)). ]

I would vote for the list. most folks have a calculator so multiplication is fairly easy. A chart would take up a lot of precious room
