I'm looking for info on "nightvision" problems, can you help?

sometimes if you have that problem\ncould be asstigmatism\nthat could be the problem

you'll have to contact bluelight regaurding that issue.

Hi, my freeview is jut fine. I think that it may be your box rather than the signal as they are made on the cheap. if it does work, watch Goldeneye on ITV2. It's great.

When blending two images together, one of the hardest things to get right is the lighting.  I have the feeling you are experiencing problems at a more basic level.  You might want to spend a day learning about every tool in the box, and I recommend especially getting to know your hotkeys for a faster working speed.  \nAfter the tool box, learn how to work your layers, which is so important to understand how to use for a beginner.  These are the fundamentals.  Finally learn all the file, edit, menubar items, and treat yourself at last to the filters.  It is going to be frustrating the first couple weeks, but once you get the hang of it, it's addictively fun.

Screen savers help but i WOULD RECOMMEND antireflective coated lenses. Also get up and get away from the monster for breaks.  Better light  works the best.

check your monitor settings and see if you have a Degauss features.  Most modern monitors do.  If you are lucky this should fix the problem.

try getting the latest drivers and lok on the nvidia website at http://www.nvidia.com/page/home.html \n       there are loads of links to technical helplines and it would be a good idea to go to the viewsonic site at http://www.viewsonic.com/ for info avout your new purchase\n      as your graphics are intergrated it might be retricted to certain resolutions,and also because your tft is a widescreen may be a added problem\n      try right clicking and go to "nvidia display"then in the nvidia control interface try experimenting with the monitor settings as when i use to have a nvidia card i allways changed my resolution this way and not in display properties(you find you can get higher resolution in the nvidia control panel)\n      good luck

Night vision\n\n Two American soldiers pictured during the 2003 Iraq War seen through an Image IntensifierNight vision is the ability to see, whether through biological or technological means, in a dark environment. Most instances, whether biological or technological, use a combination of two approaches: enhanced spectral range, and enhanced intensity range.\n\nContents [hide]\n1 Enhanced spectral range \n2 Enhanced intensity range \n3 Biological night vision \n4 Night glasses \n5 Thermal vision \n6 Image intensifier \n7 Night vision goggles \n8 See also \n9 Patents \n10 External links \n \n\n\n[edit] Enhanced spectral range\nEnhanced spectral range techniques make the viewer sensitive to types of light that would be invisible to a human observer. Human vision is confined to a small portion of the electromagnetic spectrum called visible light. Enhanced spectral range allows the viewer to take advantage of non-visible sources of electromagnetic radiation (such as near-infrared or UV radiation).\n\n\n[edit] Enhanced intensity range\nEnhanced intensity range is simply the ability to see with very small quantities of light. Although the human visual system can, in theory, detect single photons under ideal conditions, the neurological noise filters limit sensitivity to a few tens of photons, even in ideal conditions [1]. Some animals have evolved better night vision through the use of a larger optical aperture, improved retina composition that can detect weaker light over a larger spectral range, more photoefficient optics in the eye, and improved neurological filtering which is more tolerant of noise. Enhanced intensity range is achieved via technological means through the use of an image intensifier, gain multiplication CCD, or other very low-noise and high-sensitivity array of photodetectors.\n\n\n[edit] Biological night vision\nIn biological night vision, molecules of rhodopsin in the rods of the eye undergo a change in shape as light is absorbed by them. The peak rhodopsin build-up time for optimal night vision in humans is 30 minutes. Rhodopsin in the human rods is insensitive to the longer red wavelengths of light, so many people use red light to preserve night vision as it will not deplete the eye's rhodopsin stores in the rods and instead is viewed by the cones.\n\nSome animals, such as cats, dogs, and deer, have a structure called the tapetum in the back of the eye that reflects light for even better night vision than humans, in which only 10% of the light that enters the eye falls on photosensitive parts of the retina. Their night vision likely falls between a Generation 1 and Generation 2 image intensifier.\n\n\n[edit] Night glasses\nNight glasses are telescopes or binoculars with a large diameter objective. Large lenses can gather and concentrate light, thus intensifying light with purely optical means and enabling the user to see better in the dark than with naked eye alone. Often night glasses also have a fairly large exit pupil of 7 mm or more to let all gathered light into the user's eye. However, many people can't take advantage of this because of the limited dilation of the human pupil. To overcome this, soldiers were sometimes issued atropine eyedrops to dilate pupils. Before the introduction of image intensifiers, night glasses were the only method of night vision, and thus were widely utilised, especially at sea. Second World War era night glasses usually had a lens diameter of 56 mm or more with magnification of seven or eight. Major drawbacks of night glasses are their large size and weight.\n\n\n[edit] Thermal vision\nFar infrared, or thermal, sensing is generally not considered night vision because it is constructed with mechanisms substantially different from the methods used to sense visible light. It is possible to construct an imaging device with microwave energy, sound, or any other signal that is reflected or radiated by objects and can be focused and sensed, but these are also not genera

need more information.  What website?  What kind of error messgage are you receiving?

Didn't got the question do you want the solution for all the problems of goodman's Introduction to Fourier optics book? Well I do not think I have them any more if you want a specific problem I can help you. I can even try to get a chapter solution for you. Just tell me each one, I can try to get it for you, I do not garantee but I think I may have a way to got them just send me an email (I have a yahoo email). If you have the solutions and you don't understand tell me each problem I can do it in more detail probably, not garantee at 100% but at a good 90% .

The visual card seems to be the problem

You should be able to enable 3d accel, try using the video cared menu to do it. or try a better graphics card.

Always make sure that the light is behind the camera, else the auto-exposure will close down, giving you a rubbish result. To cut the jerkiness you may be able to increase the frame rate on setup. Also go to 'Properties' and shift the 'Gamma' this may help.

Most likely it's getting Old...You can try to correct this with you screen settings via you Video card...First try you gamma setting, contrast, brightness...but as cheap as Monitors are now, you better off getting a New LCD flat screen monitor anyways...

The only way to really fix that is to exercise your warranty/consumer rights. If it's not acceptable most retailers will send you a replacement. If they have a dead-pixel policy that says one is ok, there's not much you can do from a technical perspective. The circuits are just too small and delicate to work with.

try unplugging power ,and from video board,\nre-attach and reinstalling drivers,\n\ncheck:\n display properties/ settings/monitor / monitor settings / MHZ \nset at 60 or 70 etc. ...\n\ncheck monitor buttons brightness/contrast , default settings,

Check your Monitors manual for instructions on how to access the built in menu system. Often its obvious like a big menu button on the front!\nAnyway since you don't describe exactly what you mean by light I would suggest trying to reduce the contrast a little and or the brightness.\n\nIf this doesn't give you satisfactory results some graphic cards have system software which allows you to configure the brightness and gamma controls for the video output.\n\nJohn
