Question about Kodak EasyShare C663 Digital Camera

Size of JPEG file produced by this camera

When I bought this camera (6.1 mp) I expected to obtain a JPEG file somewhat larger than my previous 3.2 Sony which produced a file size around 1.3 to 1.5. To my disappointment I've found the file size produced by this camera to be around 1.5 to 2.0. My daughters 6.1 Sony consistently produces file sizes of 2.50 to 2.90 and the quality of the photos is significantly better than mine. I have my Picture Size set at 6MP all of the time. Kodak pooh-poohed the problem saying it was due to subject matter, color and etc. I have not found this to be the case. Any ideas?

    I kind of had a feeling there was some compression somewhere. Ok, but now how come Sony 3.2 and Sony 6.1 show under Properties that their dpi is 72 while Kodak 6.1 says their dpi is 230. Shouldn't Kodak produce a vastly superior picture? Anyway thanks for the help on the original question. It was driving me crazy.

The general rule is a jpeg is halve the mb of the resolution-6 mp =3mb file size-kodak uses a ton of compression and this is the main reason why-put a memory card in a kodak and you pick up about 20-30% more capacity than other brands!

    dpi numbers are really only used in printing terms as to how many dots of ink a printer can lay down-most 4 x 6 printers will only use and can only fit 3.5 megapixels in that size area-take a 10 mega pixel photo and printer will discard 2/3 of data used for print-that's why general rule is 2-3mp 4x6's-4-5mp 8x10 is the max you really need for great prints!

My image quality setting is at the highest JPEG level but am still only getting file sizes at 3.2 or smaller.


Go to Image>Image Size, make sure there is no tick in "Resample Image" and change the resolution from 72 to 300 pixels per inch.

My images save at sizes of 3-4 MB!!! how can i get them to be (way) smaller files??? powershot SD790is digital elph


Your solutions are varied, but the results will be (mostly) the same. Option 1: Lower the resolution and quality settings on your camera. If you are seeing 3-4 MB per photo, then they are probably at least 4000 pixels wide, and your file size will be larger to reflect that. If you set the camera to a lower quality and or resolution, you will for sure save disk space. Consequently, you will also lose image quality. If you are mainly archiving the photos for the purpose of viewing them online, on your PC, or through a digital picture frame, this is no big deal. If you intend to print, especially a large print, you will see pixelation occur in the print. This will take smooth parts of your picture and chunk colors together in a "boxy" appearance. Your second option, is to import your photos in a program like Google Picasa or many other free options, and then convert your image to a compressed format, such as a compressed JPEG or PNG file. PNG files are usually the better choice for file size, but not every devices (frames, TVs, etc.) recognize PNG files. So you may want to stick with JPEG depending on your use for your photos. Additionally, you can lower the resolution of hi-res photos within Picasa (or its alternatives) after importing the photos. This is the preferred route as you can take every photo like you want to print it as a poster, and then choose which photos to drop the resolution. This gives you the safety of shooting each picture as if you want to keep the quality and then later decide which are worth archiving at what resolution. Remember, the detail in a photo also reflects upon its size, not just resolution, if you take one 12 MP picture of the sky and another of a bunch of different color balloons, the balloon will have more color data and thus a higher file size.

How many pictures can you take on cards with 2GBS?


That depends on several factors. Among them are the picture resolution (a 12MP picture will generally take more space than a 6MP picture), the quality (BASIC will produce smaller files than FINE). In addition, some cameras allow you take pictures in RAW format instead of (or in addition to) JPEG format. RAW files are much larger than JPEG files since they include all the data that comes from the sensor, not just the processed results. In addition, the subject itself will affect the size (a blank white wall requires less memory than a finely detailed landscape, for example).

Your manual should have a page giving you general guidelines as to how many pictures you could expect to store on a card. That page may give you numbers for a different sized card, but you can simply scale the results. For example, if the page says it's for a 1GB card, simply double all the numbers.

It's also good practice to have a spare card. That way, if you suddenly get creative (or if something happens to your first card) you can keep shooting.

Slow down your shooting. The "R11" indicates that you can take 11 more images before the buffer is full and the camera will stop functioning until the images are moved to the memory card.
Select a smaller file size. Nikon cameras allow you to select from several sizes of JPEG as well as a RAW and a RAW + JPEG file. These files vary in size. If you select a smaller file size, the buffer will take longer to fill, allowing you to shoot longerTurn off long exposure noise reduction. This function causes the camera to expose twice for every image, and this can fill up the buffer quickly as those images are processed and written to the card.
  • Step 3 Select a smaller file size. Nikon cameras allow you to select from several sizes of JPEG as well as a RAW and a RAW + JPEG file. These files vary in size. If you select a smaller file size, the buffer will take longer to fill, allowing you to shoot longer.
  • Step 4 Turn off long exposure noise reduction. This function causes the camera to expose twice for every image, and this can fill up the buffer quickly as those images are processed and written to the card.

    In short, no.

    The two cameras may look similar and operate in a similar fashion, but your camera uses a 23.3mm x 15.5mm JFET sensor and the D2X uses a marginally larger 23.7mm x 15.7mm CMOS sensor, although both are considered to be APS-C sized sensors. The two technologies are incompatible. All of the image processing hardware is different as well.

    If your camera works well then there's no need to upgrade anyway: four megapixels is more than sufficient for prints above A4 size and the sensor produces very little noise. Nobody other than professionals shooting for billboards needs 12.5MP and as higher MP counts = more noise, no professional would use C-size sensor anyway for that level of enlargement. The only advantage you'll gain with more MP is that you can crop the image down more and still retain acceptable quality, but to properly benefit from this you need to be using professional grade lenses and shooting on a rock solid tripod. The only reason that manufacturers produce ridiculously high MP count sensors is that the general buying public automatically think more = better.

    If you love your camera then continue to use it: it was built to a very high standard and if serviced every now and then will continue to produce great images with little apparent noise even at higher ISO settings. The best way to invest in better photos is to improve your technique and also to use a good tripod or monopod whenever possible. Upgrade your lenses to the best ones which you can afford and you'll find that the will serve well on the next Nikon which you eventually buy.

    Don't believe the hype: you have a great camera. Four megapixels on a C sized sensor will easily outperform more than double that number on a smaller sensor camera and will be less noisy than anything with more megapixels.

    How do I set dpi on canon 50d digital slr to the highest resolutioin?


    You'll need to shoot RAW. Then in the conversion from RAW to TIFF or JPEG you can specify the DPI. You can do this in Photoshop or in Digital Photo Professional that probably came with your camera.

    DPI and Pixel Resolutions are in two different realms, though somewhat related, they are independant. Your camera produces files at the maximum resolution of 4272 x 2848. At 72 dpi, your print will roughly be 60"x40". At 300 dpi, 14.25"x9.493". At 600dpi, 7.12"x4.747", at 1200dpi 3.56"x2.373". Think of cameras in terms of pixel resolution and printers in terms of dpi. When files are inserted into layouts, the embedded dpi value is used. You just need to change the embedded value to match up with the print size you desire. Obviously, if you want a 120"x80" print at 300dpi... you've got the wrong camera. :) Source(s): This is a good site for those interested in more technical details:

    Image quality of the 3100z's JPEG format?


    I don't think you will find any major difference in quality with Epson's 3000 or 3100 compresssion compared to Canon's. I use the 3000z and shoot in low compression giving a file size about 850k - 1000k.
