Image:Gray contrast test image.svg, not featured

•  Info created by Benjamin D. Esham (bdesham) A test image to check your monitor's response to photographic shadow detail. An image that goes well with this document. Call it the 'what are you really doing' nomination. - uploaded by bdesham - nominated by CarolSpears --carol 22:19, 1 December 2007 (UTC)

•  Oppose This image is a pure technicality, useful no doubt, but why would it be featured? --JDrewes 23:55, 1 December 2007 (UTC)
•  Oppose Too dark Lycaon 00:31, 2 December 2007 (UTC)
  • Yeah the first circle's too hard see. Please use better lighting ;) Rocket000 04:45, 10 December 2007 (UTC)
•  Support I support it because it is a very good tool to calibrate the monitor for brightness and assure that what one sees reflects the tonal values of the image. --Tomascastelazo 00:47, 2 December 2007 (UTC)
•  Oppose - I can't even see the first circle... - Alvesgaspar 01:20, 2 December 2007 (UTC)

• That is exactly why this is useful. If you cannot see the first circle, your monitor is not calibrated right, and if your monitor is not calibrated right, your output will be off, especially when you fly visual. What you see in the monitor is not what you necessarily get in printing, whatever the medium (inkjet, photo lab). --Tomascastelazo 01:43, 2 December 2007 (UTC)

• You don't have to see the first circle (from the left), only the other three. Dori - Talk 01:51, 2 December 2007 (UTC)

• I will share a couple of tips with you… In Zone System photogaphy, a method developed by Minor White, Ansel Adams, and others, there are what are called dynamic range and texture range. This particular illustration is useful to calibrate your monitor for the dynamic range, that is, the tonal separations in a particular image. If you calibrate it correctly, the texture range will fall into place automatically. Now, what I do is the following: I print a picture without any adjustments where I can see in the histogram that it covers the entire dynamic range, and has a decent amont of colors. Then I place it next to my monitor and adjust the brightness and contrast settings so that the monitor adjusts to the output, and then I do the same with color adjustments. I write down the settings because they will be useful only to that praticular output medium. I have two settings, one for my inkjet and one for the photo lab. The settings will not be the same. Depending on where I will print, I ajust values in the monitor. That way, what you see is what you get. This illustration, at least, will give you a good start in monitor and output calibration.--Tomascastelazo 02:11, 2 December 2007 (UTC)

Assuming that people see the Picture of the Day and that is how they arrive here to vote, and also for the simple fact that the featured pictures are viewed via a display which is getting information from a computer -- it might be just good practice to once a year remind people about the technical aspects of what makes an image good or not good and the reasons that images are Featured and not as well as the voting guidelines. Once a year, everyone gets to calibrate their monitor and perhaps, reassess their criteria for their votes and their opinions. -- carol 07:32, 2 December 2007 (UTC)

•  Oppose. Technically useful but not FP material. The image text actually says that your monitor is too bright if you can see all four, contrary to Tomascastelazo's comment above. My monitor is regularly calibrated using Huey Pro (a clever little device and software that actually measures screen output and adjusts colour balance and brightness settings automatically). I see three circles, and the ghost of a fourth if I stare very carefully. --MichaelMaggs 09:13, 2 December 2007 (UTC)

You are correct, I left out the part about just barely seeing the first circle. Like you say, a ghost. --Tomascastelazo 19:27, 2 December 2007 (UTC)

•  Oppose This is a useful image from a technical standpoint, however nothing about it is worthy of FP nomination. Cpl Syx 19:15, 2 December 2007 (UTC)
•  Oppose Too simple to create. Not enough to justify being a FP. --Lerdsuwa 15:57, 3 December 2007 (UTC)
•  Oppose, as above. Poromiami 20:31, 3 December 2007 (UTC)
•  Support Value from simplicity. I remember back a year or two ago, we had this tool on the main FPC page to make sure everyone used a similar brightness. It is truly an invaluable tool for many of us in my opinion. Freedom to share 21:32, 5 December 2007 (UTC)
•  Oppose C'mon guys. This is just a tool. Where's the creative input? Of course, please discount my vote, I can't see the first circle. :-) Rocket000 04:59, 10 December 2007 (UTC)
