  1. Go to www.dcresource.com and read the review of the Canon A540. This is in the family of the new Canon releases and also uses the 6 mp sensor that has the ISO 800 rating.

    This is probably similar to the high ISO results of the SD6xx series.

    The results don't look that good.

  2. I have the G6 and it is a very good camera. The G6 is an older design than the A620. Has a slightly better lens, and can use external flash and will shoot RAW.

    The A620 has the newer Canon electronic processing system and may be slightly faster with the overall picture focusing and taking of image.

    Both cameras are very good. If you don't care about the RAW image shooting and external flash, I would get the A620.

     

    You should look at some of the reviews on dpreview.com and dcresource.com.

  3. When you shoot in RAW the camera makes a thumbnail image in JPEG. This what you are viewing in the camera, the small thumbnail image and not the RAW file. That is why the quality looks so bad, it is.

     

    You must process the RAW file with the Canon supplied software or some other 3rd part software (i.e. photoshop).

    From the Canon Zoombrowser (i.e. windows) choose "Tools" then "process RAW image".

  4. The digital resolution of your camera at the best setting is 2560x1920 pixels. The 72 dpi is what the camera mfg. has determined for the camera.

    The 200-300 pixel/inch is what is considered a size for printing the image. Usually 300 to 360 is considered ideal.

    When you resize you image in photoshop keep the "resample image" check box off. After you resize (i.e. 6 " in width) you will note the image pixels/inch will change from 72 to something higher (i.e. 426+). You divide the pixels of the image i.e. 2560 by 6 inches to get the new density. The number of pixels does not change.

    When you resize with the "resample image" box selected you can change the actual number of pixels (or create pixels) by how you set the parameters of size and pixels/inch.

    Hope this helps some.

  5. Zoombrowser which comes with Canon camera will show you the data. After you have started Zoombrowser, you can put your mouse pointer over a picture of interest, then right click, choose properties. This will show you the EXIF data.
  6. I had an Olympus C-3000 this same type of sympton happened to me. I sent it off to Olympus to be fixed (via local camera dealer). When it came back, after about 10 shots, it failed again the same way. Back to Olympus a second time. Came back and failed again after about 10 shots. This time dealer worked with Olympus and I was given a new reburbished camera (same model). This whole thing took about 4 months. Time frame was a couple of years ago.
  7. I don't have a good answer for Pana Vue but I know that this program can be downloaded for a 30 day trial. Try it out.

    Also check out PTGui which is also a 30 trial. You can find the addresses with Google.

    I have tried PTGui and it is good but also harder to learn.

    On some pictures I have had better results with PTGui over the product that comes with the Canon camera.
