camera suggestion for this picture

Recommended Posts

What about trying a wide dynamic camera for this shot? It should compensate for the light differences.

I'm not sure what I can link to and not link to because of the board rules. We are currently looking at the Videology 20E709W for some WD captures.

 

Here's a definition of WD I pulled from a google search:

One of the most fundamental "law" of photography is that you never take a picture with bright light source, such as the sun in the background. Most of us know what happens when we do this: A black shadowy silhouette in front of a bright light, unable to distinguish any physical features. Same has been true in CCTV surveillance photography. Recently however a breakthrough in optical engineering called the Wide Dynamic Technology enables a camera to take picture for what used to be off limits for surveillance photography.

Whoever wrote that definition, obviously doesn't have much knowledge of photography post 1920 something. When I was a kid (no jokes please!) you were always told to take photographs with the sun behind you (flat lighting, minimal shadows).

 

For anyone with a reasonable knowledge of picture taking, dealing with "contre jour" or against the light shots, can produce some quite startling and interesting images.

 

That said, CCTV is a whole different ball game, but whereas engineers have long sought to use the wide dynamic range of some camera imagers to produce a usable picture in backlit conditions, the fact is that for perhaps 50 - 75% of everyday situations, you can just as easily manipulate available lighting (either visible or IR) to produce a more pleasing and evenly lit image.

 

The idea that WDR is a new phenomenon, does somewhat overlook the fact that previous generations of Vidicon tubed cameras, had sufficient dynamic range to cope with lighting from perhaps 5 - 100,000 lux simply using a fixed iris lens (16mm f1.6 used on 2/3").

Rory,l just ordered that ge camera from spytown,what adjusments should l be looking to do with the settings of the camera,as l have little to no experience setting up the cameras for optimum viewing.l know l have to consider lighting background and foreground etc,but in general what would my settings be for this camera based on my bar lighting!!

Set to DD

Everything else can be default, you can turn on SAGC if it looks better, that makes it brighter, since its indoors only it could help, outdoors i never turn that on. BLC can stay on by default, if you have brightness/glare issues then turn it off. You shouldnt need LinkLock but wont hurt to leave it on default.

thanks rory you have been a big help, along with other members,this forum is a valuable learning tool for the novices.l managed to run cameras,put on connectors set the focus using a second monitor on site,all knowledge gained from this forum and even some issues with routers!!!

no problem Airick,l just bought them ,they should arrive by wednesday and l also managed to pick up 2 panasonic wv 474 domes for $400.00 for both of them!! so l will install them by the weekend!!

 

Rory if you could advise me on the ideal settings for the 2 panasonics,based on the light conditions in my bar,l would really appreciate it!!l am going to put them near a lighter area(still dim though)

That is a smokin deal for those cameras. Did they fall off the back of a truck?? Where did you find those so cheap? You are talking about these right? WV-CW474AS
