Talk:High-speed photography

Untitled
This page is heavily weighted by my own experience in the industry. I don't know much of the history with any precision, and am afraid that at best I could only read articles and summarize them. That doesn't interest me, much. I think the information on frame rates, sensor (film or electronic) sizes and formats, and run times should be tabularized for quick reference. Also, I think this should be an engineering stub, but there's no template (ahem) Ehusman 23:16, 31 December 2005 (UTC)

This is no longer a stub, and I got some good background from a paper written by Gil Pendley. Thanks to everyone adding images. Ehusman 04:28, 26 July 2006 (UTC)

Fast light?
In the second paragraph it reads "The second is that a series of photographs may be taken at a high sampling frequency or frame rate. The first requires a sensor with good sensitivity and either a very good shuttering system or a very fast light.". I do not understand the "fast light" bit. All light travels (if memory serves) at 380,000,000 miles per second. How can you need "fast light". I don't know what to do, so I will leave it for now.--Squid tamer 02:55, 8 November 2007 (UTC)


 * The exposure time can be regulated either with a fast shutter speed or with pulse lights which only flash for a small interval of time. I believe that is what is meant. Girolamo Savonarola 05:06, 8 November 2007 (UTC)
 * That is correct, that is what I meant. I guess it could be improved. Ehusman 02:51, 11 November 2007 (UTC)

Section: Stroboscopy and laser applications
It says to see a photograph. Where? --Milkbreath (talk) 00:30, 23 November 2007 (UTC)

CCD vs CMOS
Speaking of CMOS, the article says "[...]the image quality and quantum efficiency of CCD still compare favorably" ...Are there any reliable sources for this? —Preceding unsigned comment added by 132.207.137.202 (talk) 17:00, 17 June 2008 (UTC)
 * At this point, I think I'm ready to concede on this point: CMOS has largely caught up to CCD for everything except astronomy. Ehusman (talk) 00:33, 15 August 2009 (UTC)

Motion capture
This article seems to be biased towards high speed video capture and contains almost none on (what I understand to be) the traditional meaning of high speed photography, which consists of taking photographs at extremely low shutter speed in order to capture events that occur too fast for the human eye to see. This is especially odd since there are 3 pictures that are examples of the latter, yet no information on how they are produced. —Preceding unsigned comment added by 70.70.145.85 (talk) 13:29, 4 December 2008 (UTC)
 * The "traditional" meaning of high speed is what is portrayed here. It wasn't until faster film and then strobe lamps were available that the other meaning became feasible. Good point on the creation of those images, though. Ehusman (talk) 00:35, 15 August 2009 (UTC)


 * I suggest that a working definition of High Speed Photography is the production of images to see events that are too fast for the eye. This would include streak cameras, compensated drum cameras, image tubes, electronic flash especially the high speed flash, high speed cine and video, the Kerr cell and anything else that complies. I don't know if there is internet corroboration. If any subject gets heavy then it can be hived off to a page of its own. Reg nim (talk) 19:24, 3 November 2009 (UTC)

hyphen
Shouldn't this more properly be high-speed photography and high-speed video? —DIV (138.194.12.32 (talk) 02:42, 2 September 2009 (UTC))

High speed outside broadcast television
Hi there. I have some pictures of super-slo-mo, and more recently, an imovix sprintcam v3. If they're useful for this article, please let me know at my talk page and I'll upload them to commons.

Kodak in Early Applications .....
I do not know the full history, but Eastman Kodak certainly developed their high speed 16 mm camera past the prototype. The Type 11 was intended for scientific and industrial use, capable of speeds up to 3000 fps. A hand operated rheostat was provided on the side for acceleration control, if too fast the film broke, if too slow the film ran out before reaching full speed. This model appeared some time about 1938 or so and was used for weapons development in the 1939/45 war. Then in 1944 came the Type 111, this was a Type 11 but with an automatic acceleration control so no operating skill was needed. Originally made of cast iron, it was then produced in aluminium and was widely sold to laboratories, product and production development engineers. This is a vital part of the history. Here is a link http://people.rit.edu/andpph/text-eastman-high-speed-camera.html. I believe that the Fastax used 8 mm film, Kodak used 16 mm giving better quality for analysis. I will revise the page in a week, I will watch for comments. Reg nim (talk) 22:24, 2 November 2009 (UTC)

Fastax References
I do not know how to insert a reference, can someone who knows how to access reflist|2 please insert these for the Fastax : http://owyheesound.com/fastax.html & http://owyheesound.com/fastax2.html. Many thanks. Reg nim (talk) 17:23, 8 November 2009 (UTC)

Fastest High Speed Camera Frame Rate
Hi. I'm rather curious...Do we know what the fastest frame rate ever attained is (in FPS or Frames Per Second)? That would (maybe) be useful to include in the article, depending on whether it's necessary to include such info. Thanks. 67.182.237.57 (talk) 00:59, 29 March 2011 (UTC)

I saw a Dynafax that could achieve 1 million fps for a few frames. There are a few modern electronic cameras that can do that. Hamamatsu, I think? Ehusman (talk) 22:41, 24 December 2012 (UTC)

This article needs an entry in Simple English Wikipedia like nobody's business.

Techniques, methods, etc.
This article is in serious need of sections describing the purposes and techniques of HSP. For example, how is motion smear characterized, measured, and managed? I remember these as being frequent topics in Bill Hyzer's articles and UWM seminars. Ehusman (talk) 02:02, 1 August 2014 (UTC)

Cantaloupe was spelled as canteloupe
Corrected. But please don't change the same word in filename. Jon Ascton   (talk)  10:55, 3 July 2016 (UTC)
