I just brought new 6d.

MegaPixelwise,  why my photo size is just 4.3MB  ????

why I'm not capturing higher size pictures  in JPEG  ?

Is there anything I need to change  ?

like this one  ?????

The 4.3MB is the size of the JPG file in bytes.  This is not to be confused with the number of megapixels in the image, or the number of megapixels of the camera sensor.

Honestly, I don't even know why they show you this number on the little screen.  It's theoretically a very rough indicator of how sharp your focus was, but only in some circumstances.

You mean sharpness is related to that filesize  ?

The more detail or noise is in an image, the larger the resulting JPG (e.g. a blurry and/or uniform image vs. a sharp complex landscape). The more data, the less compressed the JPG engine will be able to make the image.

You've already been given the answer but I will try and expand the explanation a bit.  JPG is a lossy compression file format for images.  The camera also can shoot in RAW format, which uses lossless compression.

In lossless compression the file rearranges the information so that any patterns that are repeated in the image are stored once instead of 2/3/4/??? times.  RAW data is also stored in 16 bits per channel per pixel, as your ADC is 14 bit.

In a lossy compression scheme you actually throw out some of the data, usually by converting the image to HSL format and storing less luminance data, for instance.  JPG is an 8 bits per channel format, so it's much less data than the RAW information.

In short, the more patterns in your image, or closely related color values, the smaller the file size, so an image with a bunch of evenly lit solid colors will result in small files, while a photo of something high frequency (lots of rapid changes in the image) will result in a large file size.  Noise in the image counts as high frequency data, and does not compress well.

You can adjust the size of JPG + RAW images in the menu to shoot small, medium or large and will affect the MB size of the files.

Sorry, don t understand why you would care about JPEG size.

Always shoot with raw !

if you want a JPEG for quick evaluation etc add that. But your images need to be in RAW.!

As with many things in life a great photograph has strong appeal for what is NOT in the picture.

That is not entireley true is it?

Shoot in jpeg if you get perfect results everytime and never process your photos, not today and not in the future....

RAW is the best format so yes do shoot in RAW or RAW + jpeg.

The answer is because that's how big your file is.  I set up my 40D (10megapixel) camera for the same settings I can see on your screen and got a file 2.87MB (Large, Fine, JPG).  Same scene in RAW was 11.1MB.
