Looking at Size and Quality Settings

Have you ever wondered why every time you transfer a photo to your computer it is so large. And wondered why, I know I have. Is it a camera setting or the photo editing software that you are using?

Size Setting

But then I noticed I have a size setting on my camera, in other words setting the number of pixels that can be used in the image.

My camera’s default setting is 2560 x 1920 pixels which is also the highest setting without interpolation. Once in the photo editing software it is 90 x 67cm with a 28.346 pixels/cm. That’s huge. I also have some other pixel options on the camera and they are:

3072 x 2304 (interpolation)
2048 x 1536
1280 x 960
640 x 480

The more pixels the better and sharper the image will look and thats also why the photos come out so large, the more pixels the bigger the file size.

Quality Setting

Underneath the size setting I noticed a quality setting for images. Which gives me a choice of:

Fine - low compression rate
Normal - Normal
Economy - High compression rate

Conclusion

At the end of the day I want to take photographs that are high in quality and look sharp enhancing the detail in the shot. So the setting I would keep as high as possible and play around with the normal or low compression rate.

I think these settings are geared towards increasing the amount of images that you can take on the camera. And that would only be useful if you have a small memory card. I use a 1gb memory card and that is plenty for me, I can take up to 1,000 photos on my camera using the 2560 x 1920 size setting. Although that may change if I use a low compression rate I can’t see it changing the amount of photos I can take drastically.
