How to take lume shots
The "Meatball discussion"

How to take lume shots?
I found a great place to take lume shots without a tripod: the bathroom sink! Thanks to the swiveling lens of the Coolpix, the camera can be simply placed on the sink while the watch can be placed into the sink. The light switch is preferably in reach of the left arm, the right index is on the release of the camera to keep the focus at the correct length, then charge the watch's lume with a strong torch light, turn off the bathroom light off and shoot and you get useful lume shots without too much preparation overheads and props. Alternatively if your light switch is too far away from the sink, use the left hand and illuminate the watch dial with the torch light, then turn the torch light off and take the shot. Of course a desktop lamp can do the same, only I noticed that there is always some ambient light in a living room or office.
Please note that this method will not produce "fair" lume shots as we tend to "charge" the luminous color unduly. There have been several attemps on the to define conditions and variables (e.g. a time row of pictures taken after having exposed the watch to a light source). Even Luminova will look great and glow like SuperLuminova if you use the above methods. And if you play with the Contrast/Brightness settings, you will be able to create "extreme" luminosity. Be aware of that also if you ask someone to post a lume shot of a watch that is on your shortlist.

To Meatball or not to Meatball - that is the question!

Thanks Chris L to teach me the "Meatball" expression in conjunction with luminous dots on second hands. Or in conjunction with discs at the tails of second hands that have the function to reduce the momentum (symmetry) and thus save winding energy or battery! The newly arrived TRASER 3105S triggered this discussion. I posted a picture of it on the and noticed that when the tail of the second hand crosses the minute hand, the minute and hour hand looked the same for a second. I found this confusing, yet since it occurs only 1440 times a day and only for a second, it might not be a critical thing nor worth discussing. However WIS tend to spend considerable energy on topics that seem bizarre ;-)

Different ways to balance the second hand
What the discussion above obviously spurred, are different ways how watch companies add counterweight to the tail of second hands. Here is a great picture from Adam in NYC (PMWF handle) from a Stocker & Yale:

This watch uses a non-luminous "meatball" and also uses a non-luminous tip of the second hand. When seeing this picture, I was wondering what my most classic SEIKO Diver's SKX007K exactly does in this regard. I was surprised to find this when taking a lume shot exactly one minute after I took the lume shot above. On a side note: I had looked a thousand times at this dial, but never really observed all the details regarding the "meatball" and the tip of the second hand.

It was a lucky coincidence that I took the shot exactly after one minute, I did not time the shots. What I find again confusing is that in the dark the luminous "meatball" will be conceived as the tip of the second hand, while during lit conditions, the white tip will intuitively act as the tip of the second hand. Maybe I am the only WIS that is confused by this "lost 30 seconds" effect. Most people seem to like lumed tips of second hands and that the counter weighed end of the second hand also looks esthetically OK. There seem to be a lot of variations out there and this is definitely and interesting topic for those that love to read their watches in the dark. Also most people seem not really too concerned whether the tail end of the second hand or the tip is lumed. I had posted the information on this page on the on June 6th 2005 and would like thank to all the posters that have contributed to the thread!
