Don't confuse bytes with pixels. A pixel is point of color. A byte is a unit of computer storage. A picture with 10 million pixels may or may not require 10 million bytes of storage.

As an exercise, take a picture outside your window, properly exposed and focused. Now put your camera into manual mode, select a fast shutter speed (1/1000 will do), put the lens cap on, and take a picture. Compare the two file sizes. The first file should have a lot of detail in it and will be quite a bit larger. The second file should be all black. The two pictures will have the same number of pixels, but require different amounts of storage.

In the worst case, each pixel will require three bytes to specify its color. JPEG files will be compressed so it's not quite this bad. At the other extreme, it doesn't take many bytes to say "3872x2592 pixels, every one of them absolutely black."

SOURCE: Viewing jpeg files

Any camera is 'Blind' to JPEG files
Camera generate EXIF files a JPEG with extra data
Computers images editing software in the main strip off the this extra datae and therefore the camera can no longer 'see' the image.
There is software that will restor the Exif erxtender
Irfanview is one[a Free down load]

I have olympus camedia 4.0 mega pixel. old camera. need to know how to change the camera photo storage from 18 photos to at least 64 photos storage


Hi, jamesepatton, and welcome to FixYa.
I am going to assume that you are referring to the camera's internal storage, as opposed to the camera's removable storage card.
Obviously, to increase the storage on a removable card, one need only purchase another, higher capacity storage card.
To change the camera's internal storage capacity, one needs to reduce the resolution of the pictures one takes.
Example- your Olympus is capable of taking a 4.0 mega pixel sized picture. This size picture can generate a fairly large data file (after all, pictures- like Word documents- are only data files!) While this is what is normally programmed into the camera at the factory, you are not 'married' to this size. In the "Setting" menu of the camera, there will be an option to change the mega pixel (mp) setting. Try lowering it to the next lower setting (say, 3.0 mp) and shoot until the camera tells you it's full. You may have to try several different mp setting, but eventually you'll land on the right one. It's going to depend a lot on what is in your pictures as well, as different scenes and content can affect file size.
A quick note here: Lowering the mp setting will affect the quality (and/or resolution) of the photo. I have found that for a great majority of the photos that I personally take, a 2.0 mp setting is just fine. I am by no means shooting magazine covers or entering my pictures in contests, I shoot 'em, print 'em and save 'em. Just your basic home pictures.
If resolution/quality is important, I would highly recommend that you save ALL pictures to a removable memory card and leave the camera set on 4.0 mp.
Good luck, and let us know how you go!

Can i print a picture in just seconds


Reduce the size of the picture. it will help a little bit....but truely it depends upon the printer that how fast it prints,

one way to reduce size is to just open it in MS paint and then save back in jpeg format it will reduce the size upto 80 percent with no pixel damage.

take care

Photo storage?


It depends on the picture resolution and the size of the memory card.
Normal JPEG 2048 x 1472 : 11.0 - With 16MB built-in memory , Fine JPEG 2496 x 2016 : 19.0 - With 16MB built-in memory , Normal JPEG 2048 x 1376 : 19.0 - With 16MB built-in memory , Fine JPEG 2496 x 2016 : 9.0 - With 16MB built-in memory , Normal JPEG 2048 x 1472 : 9.0 - With 16MB built-in memory , Normal JPEG 2048 x 1376 : 35.0 - With 16MB built-in memory , Fine JPEG 1024 x 736 , Fine JPEG 1024 x 736

The capacity of various memory cards will be similar to the above ratios.

I hope this helps.

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:

hi there
as far as i can find out that is not possible but you could always copy and paste it into a blank word document, re size it by using the corner handle if it is still to big, send it as an attatchment and the recipient can then lift the jpeg off and do what thay want with it.

hope this helps
