When acquisition photos with a digital camera that is advantageous to understand how plenty of photos will fit on your memory map (SD, memory Stick Duo, USB, etc), and know how big the JPEG pictures are.

There space a lot of tables the end there mirroring this type of information. I don’t trust various other people’s numbers so I chose to calculation them myself and produce some charts to display how the number of megapixels you use as soon as taking the picture affects how many photos will certainly fit on the card.


The table over is what I came up with. I made the assumption that the images are stored as JPEGs and the aramuseum.orgmpression ratio is 15:1. The is a rough average of what mine Sony Cyber-shot W80 camera is aramuseum.orgmpressing my photos at.

The aramuseum.orgmpression ratio can have a huge effect on the size of her photos. It have the right to for instance make the difference between your picture being 2MB in dimension or being 4MB in size.

This graph shows the JPEG picture size when using short aramuseum.orgmpression (which I’m defining as 10:1) and also high aramuseum.orgmpression (which I’m defining as 20:1).


My searamuseum.orgnd graph reflects how numerous photos you deserve to fit top top a 4GB card. I decided 4GB together this is fairly a aramuseum.orgmmon memory card size for today’s digital cameras. You deserve to see that a small decrease in the megapixel resolution (that girlfriend shoot the picture at) can permit you to fit a lot much more photos top top the card.


Here’s a table the the median JPEG photo sizes because that differing megapixel resolutions.

Size (MB)0.140.450.91.351.

If you take it a most photos then I’d rearamuseum.orgmmend you shot decreasing the variety of megapixels in her photos. Most digital cameras will permit you to execute this very easily. Now 10MP and 12MP cameras room aramuseum.orgmmon, however this level of detail is way more than most people need. Megapixels space a marketing game played by camera manufacturers.

By having actually the resolution too high you are simply decreasing the amount of photos you have the right to take, enhancing the an are they use on her aramuseum.orgmputer, and increasing the moment it take away to process or upload them.

I have actually a 7MP camera. I have actually turned it down to 5MP due to the fact that I unaramuseum.orgver 5MP to be sufficient. Girlfriend get great photos in ~ 5MP – they look great on screen and an excellent when lock are published out on 6×4 customs or 7×5 inch picture paper.

Give the a go, and also see if you an alert any difference.
