Hi Eric. We had this discussion some time ago. The is no "standard". A scale cube (or anything else) is meant to show scale. Period. A 1cm cube may be useful for much of the meteorite photography that is made of smaller samples, up to several hundred grams, but once you start photographing larger objects, a larger scale object should be used.
Because of this the scale on the cube, or whatever else is being used, MUST be shown in the photograph, or at the very least (and much less useful) cited in the photo description. Anything less makes the scale used practically useless. Since the photo and the description could potentially become separated, showing the scale in the photograph is always preferable. We've all seen NASA photos of lunar samples that use a 1 inch cube for scale. Unfortunately in many of them the photographer did not understand what the scale cube was actually being used for and did not show the 1 inch marking on the cube in the photos. This means that anyone who doesn't know the actual size of the scale cube, or someone who assumes the cube is some "standard", say 1cm, you will assume the object being photographed is a different size than what it actually is. If you ever see a scale cube in an image and you can see the scale on the cube, ignore it entirely. It's inclusion in the image is essentially useless without the scale being visible. -- Richard Kowalski Full Moon Photography IMCA #1081 --- On Sat, 8/14/10, Meteorites USA <[email protected]> wrote: > From: Meteorites USA <[email protected]> > Subject: Re: [meteorite-list] AD: since people are talking about > photographing your meteorites > To: [email protected] > Date: Saturday, August 14, 2010, 2:09 PM > Just wondering... maybe I don't > understand. > http://scaleobjects.com/photographycubes/photography.html > > But, what's the point of a 1 Inch or 2 Centimeter "scale" > cube when the > standard is 1 Centimeter?
