Your Questions About X10
What are the little color squares used by photographers?
I recently saw some proofs shots of some models and there are several shots of them holding litlle color squares, about 8″ X10” looks like a color guide???? what are this color things used for and how.
It’s called The Macbeth Color Checker, used for color correction.
In college we used to use it with this machine that would read any square and tell us what the color value was. Then we would correct it while printing. Photoshop is a bit faster now.
Here is a link talking about it… Though his assistant is holding it wrong, it needs to face directly to the camera.

Wall shelves offer a ton of storage space without compromising floor footage. Every room in our house is tiny, and wall shelves, some with small baskets on top, make a huge difference.

You can mix them as they both have the same properties…just make sure its white cement and not bags of mortar…
How well do tea lights illuminate? Do all tea lights float?
I’m planning a photoshoot where the primary source of illumination is intended to be tea lights floating in water-filled glass cups, glass bowls and glass pans. The cove is fairly small (maybe no more than 10′x`15′, more likely 5′x10‘) and has walls lined with a shiny steel. It’s really more or less a corner of large room containing a much larger cove of more matte material.
Since I’ve never bought tea lights before, I need to know if there are some that float and some that sink.
In standard units of measure, about how much light does one tea light give off? I know some of you are going to say “one footcandle”, but it’s not an acceptable answer since I want to compare tea lights to ordinary candles and other illumination to calculate how many I’ll need minimum.
I’m not too worried about buying or lighting too many, except that the more I light, the more glass bowls I need to procure for the photoshoot.
I found your question very intriguing. So I decided to experiment. I went to BigLots and bought some ordinary votive candles (vanilla scented) to see how they would float. The lie on their sides, doh! I held a quarter with tweezers in a butane lighter flame, put it on a hard surface (that wouldn’t melt) and pressed the bottom of the candle on the quarter until the candle melted enough to hold the quarter in place. I put the candle in the water… It sunk!
Next! I did the same thing with a dime. Voila. The candle floated upright but pretty low in the water. Nevertheless I lit the candle and it’s been burning steadily for the past two hours and probably will for some time. The wick has burned down and there is a depression in the center of the candle. The flame is actually partially below the surface of the water. Cool!
You could probably get the candle to float a little higher in the water by using a washer that’s a little lighter than a dime (cheaper too). The votive candles I used measure 1-3/8″ in diameter and 2-1/4″ tall. They were only $1 for 4 which is cheap enough. Maybe this will solve your problem. Let us know what you come up with and post your pictures. I’d love to see the result.
Edit: It’s been burning for almost 3 hours now and still going great. As the wax burn up the candle rises in the water. It just may continue burning for a lot longer. Next I’m going to try it with a dozen, or more, floating in a bowl water. Thanks for triggering my curiosity.
BTW, many years ago I did some figure studies on 100ASA color print film using the light from a single candle.
