Question about Canon EOS-20D Digital Camera with 17-85mm Lens

1 Answer

Dead Pixels??? I am an amateur photographer and I do not know too much yet so bare with me. I have been taking pictures of the moon lately to get the feel for my new camera (Canon EOS 20D) and I have noticed something kinda strange. When I?m looking at the pictures on my computer, and I zoom in past 100% on the right hand side there is this tiny white spec and blue dot. When I zoom in more the white spec is shaped like a star of five squares. It seems to be on all of my photographs (it?s in the same spot every time), or at least the ones I shot in low light conditions. I have heard of some people talking about, ?dead pixels? and was thinking maybe that?s what it is (I was not shooting in RAW.) Or maybe there is some dust or something on my sensor. Anyone else seen this?

Re: Dead Pixels???

It's a hot/stuck pixel. It's not dust. If it's always the same shade of white and on every shot it's stuck. If it's some shade from grey to white and only shows up on longer exposures, it's hot. Can't be fixed. Canon should be able to map it out, but I'm not sure of their warranty policy. Sometimes warranties on sensors specify a maximum number of defects. Very few, if any, warranty a sensor to be perfect, with zero dead, stuck or hot pixels. If you don't specifically look for it in a print, it's unlikely that you (or anyone else) will notice it.

I would like to be able to take a good picture of a full moon on a clear night.


You're going to face two separate problems here.

One, the moon occupies a rather small portion of the night sky. Even fully zoomed in, the moon is going to be not much more than a bright spot in the sky.

Two, the camera is designed to assume that almost every scene is an average brightness. Given how much of the scene is a black sky, the camera will attempt to render the sky as average (what photographers call a "medium gray"). This will result in a picture with a gray sky and a featureless white blob for the moon.

If you think about it, the full moon is nothing more than a really big rock under a midday sun. Thus what you want is the same exposure as when taking a picture on a clear sunny day. Unfortunately the camera is going to be fooled by all that dark sky and try to compensate for it. What you really need is to be able to bypass the camera's light meter and set the proper exposure yourself. The C195, unlike more sophisticated cameras, doesn't allow you to do so. Sorry, but that's just the way it is.

Picture download isn't same size as camera says


First, don't confuse pixels with bytes. Though you didn't specify the model of your Sony camera, I assume you're taking 10 megapixel photos. This simply means that the photograph is comprised of about ten million points of color. When those points of color are processed and compressed (JPEG files are always compressed) they will usually take up much less than ten million bytes on the memory card or your computer's hard disk. As an extreme example, consider a photograph taken with the lens cap on. All ten million points will be pure black, and it certainly doesn't take 10MB to say that.

Second, without knowing anything about the product you're trying to create or the site where you're trying to do it, no one can help you.

Red line on the display and shows up on photos


if this red line is still on the picture when you open in the computer, I`m a fried you will need a new CCD. If the pictures are ok in the computer is probable some wire that connect the LCD are interrupted , or the LCD have some dead pixels.

Can't download my pics or video connection error HELP!!!!!


did u load the driver on your cpu.first of all, i am a photographer, film and now digital, mostly film. First of all i am not familar with this brand of camera, so i am guessing it probably is a low end consumer camera,no offense, just keep real,so i get right to the point,light change, each minute and every second, so ,in other words the less light the more time is required to make a picture.you will need a camera that allow you to have more control over it, i recommend a slr digital camera,but expect to pay any where from 400 to 3000 for one depending your style.
second of all i have some bad new, in photography, the two hard thing to photograph are fireworks and you guessit, the moon. your son will at least need to hold down the shutter(new slr ) at least anywhere from 1 to 2min, i know some moon shoot took long than that.unfortunely, the moon is just want of things that is hard to photo even for me. good luck and i hope i help

Spot metering on the Epson 3000z


The spot meter area is small because I have photographed 2 people side by side many times, focused on ones chest then found that the "spot" had slipped into the little space between them, the bad focus not really showing up when I checked the LCD. (My eyes are old and so are my glasses.) Got home and found useless pictures. Sometimes I was outdoors in the sun and couldnt check the LCD. Some of the threads say the focus spot is "off center" with no acccurate way of finding it when using the viewfinder. I take some beautiful, wonderful pictures but these errors really tear me up. I've got to get the LCD box viewer with the 2x lens viewer I guess. All those years as a 35mm Canon F1 user I would long for a spot meter almost daily. Now I see that a matrix meter AND a spot is the real choice. I hope eventually to learn to outwit my 3000Z because it does give me such excellent pictures. Sometimes there is noise on a face, sometimes it is the focus and at functions it is so embarassing to ask a principal subject to wait because the *** or ***H procedures take so long. A wedding, other than the reception, would be near impossible in *** or higher. Good Luck, Dav.

What are high resolution and standard resolution?


All pictures have 24-bit pixel depth, or 16 million colors at 144 dots per inch. The high resolution setting produces a standard size photo, 4.44" x 3.33" at 640 x 480 pixels. A wallet size photo of 2.22" x 1.67" at 320 x 240 pixels is produced using the standard resolution setting. Example: A picture with dimensions of 4.44" x 3.33" at a pixel count of 640 x 480 will have the same dpi as the same picture at a 320 x 240 pixel count with dimensions of 2.22" x 1.67" (dpi=144 x 144 or 20736 pixels per square inch). The larger picture will have a much higher resolution due to the fact that four times the pixels will define the same section of the picture in the larger photograph.

What are defect pixels?


Ocassionally images from digital cameras will have "defect" pixels. These pixels may appear in the final photograph as bright white, green or red spots that are out of place when compared to the rest of the image. Sometimes people call these spots "hot" or "dead" pixels. Usually these pixels, and other types of "digital noise" appear in the darker or underexposed parts of images; additionally, images taken at longer exposure times are much more likely to have this issue. Many Nikon cameras have a "noise reduction" or "NR" process that fixes these problem areas. When NR is activated and image exposure times drop below 1/4 of a second the NR automatically processes the images as they are saved. This Noise Reduction feature is sometimes called "Night Portrait" or "Night Landscape" Scene Modes. If these spots are seen on images photographed under normal conditions (bright light with exposure times shorter than 1/4 second) then the camera may need to be sent in to a Nikon Service Center for repair. Notice the green defect pixel near the center of this image.
