Talk:Bloom (shader effect)

message: There is a problem with "The first game to use blooming was Deus Ex: Invisible War."
According to the wikipedia articles about tron 2.0 ( http://en.wikipedia.org/wiki/Tron_2.0 ) and deus ex ( http://en.wikipedia.org/wiki/Deus_Ex:_Invisible_War ) tron was released BEFORE deus ex and therefore deus ex cannot be the first game to use it. However I didn't change the article because i don't have enough knowledge about bloom and the first games which use it. —The preceding unsigned comment was added by Monkeyget (talk • contribs) 2006-07-04 09:02:07 UTC.
:Well, it's moot now, because Ico predates them both.  There may be earlier ones, too, so I softened the qualification to "one of the earliest". — Wisq (talk) 16:46, 28 July 2006 (UTC)
thread_title: Earliest games to use blooming

message: Isn't this a real effect in real-world optical systems? Is there another name for that? My sense is that it is due in part to imperfections in optical systems. For example, looking through slightly-dirty lense will produce a fine image if the dynamic range of the scene is low, but a bright spot will illuminate the dirt sufficiently to wash out (bloom over) nearby parts of the image. —Ben FrantzDale 13:51, 28 July 2006 (UTC)

message: The current image of the game, "Nexuiz" is awfully subtle. How about an image where the bloom is more apparant?  Like Tron 2.0 or Prince of Persia? --24.249.108.133 20:15, 22 January 2007 (UTC)
replies: text: Yep, it's subtle; the problem is, most computer game screenies can't easily be used for this, because it has to fall within Fair Use, and I don't know how solid our case is here. (Though, I think the example on sprite article is pretty strong.) When I made the Nexuiz screenie, I was thinking of using DarkPlaces (fully tunable Bloom intensities), but the Quake data is still proprietary and the GPLed total conversions that don't use Quake data at all are rather weak. Nexuiz is graphically nice, but it refused to run on Darkplaces, and Nexuiz engine doesn't let me crank up the bloom levels. *sigh*However, if there's good examples of Bloom (and lack of it, for comparison!) from Ubisoft-developed & published games like Prince of Persia, that'd be mighty swell because those can be messed with with attribution; see Template:Ubisoft-screenshot. --wwwwolf (barks/growls) 17:34, 1 February 2007 (UTC)

text: FWIW, I thought it showed the effect rather nicely. Not in thumbnail obviously, but when you click on it, it's pretty apparent. Recury 23:43, 21 April 2007 (UTC)
thread_title:  Better image. 

message: Experience in the HRDI world seems to indicate that bloom is an essential component of realistic rendering. The statement that "bloom is overused", seems to me to be a matter of opinion rather than fact. Maybe bad bloom is overused. My personal opinion (rather than fact) is that bloom is necessary to display HRD properly, and will continue to play an important role in realistic rendering of any kind. Move to strike. --rerdavies 06:07, 4 May 2007 (UTC)
replies: text: I've heard the complaint leveled in response to inappropriate applications of the bloom effect, such as "blinding sheep" that glow far too much considering their supposedly diffuse texture. For instance:   an example —BlackTerror 20:00, 18 May 2007 (UTC)

text: Overusing bloom mostly pertains to video games, and is satirized in this VG Cats strip. One popular target for this was The Legend of Zelda: Twilight Princess -- User:XenoL-Type 14:28, 6 August 2007 (UTC)

text: Well if you have ever played Oblivion, you will find it is ridiculous at times. IRL I have never had to look away because someone's face was shining too brightly at me. 71.232.85.127 (talk) 07:38, 25 November 2007 (UTC)

text: Perhaps a mention could be made about crude or overpowering bloom instead of overused bloom.  Perhaps some form of criticism section?  I personally find that when bloom is correctly used, it looks pretty good, but blinding people, sheep, etcetera are too mutch.63.197.134.209 (talk) 20:46, 27 December 2007 (UTC)
thread_title: Whether bloom is overused or not

message: The blurring effect described in this article is either diffraction-limited imaging (Airy disk) or defocus (Gaussian).  Blooming is a very different phenomenon.  A pixel in a digital camera accumulates electrons in a "well" based on how much incoming light it is exposed to, and then the electrons are "read out" and interpreted as a signal level (pixel brightness).  More photons produce more electrons in the well, until the well reaches its maximum capacity.  Too many photons saturate the pixel, and some of the electrons will "spill over" into adjacent wells.  This is blooming.  This link has a detailed description of blooming by a manufacturer of digital imaging devices:  http://learn.hamamatsu.com/articles/ccdsatandblooming.html.  If the video gaming community has adapted the term "blooming" to describe defocus, then the distinction should be called out and a true article on blooming should appear in Wikipedia under the "blooming" monicker.  — Preceding unsigned comment added by 162.18.172.11 (talk) 15:01, 5 October 2012 (UTC)
