Confused on Photo File size

[trido#AC]

I am confused on the file sizes/
reading many many reviews I keep reading about 16:9 photos at 30 plus MB, but for me so far my photos 16:9 are around 13-15 MB size?
Maybe I got my Megapixels and MB confused.
One photo is 7712 x 4352 =33 Megapixels
The JPG file size is 9.37 MB

I think it depends on how the picture looks. When it compresses to jpeg it becomes smaller if it contains many similar colours :smile:

JPEG files will end up smaller when the image contains less high frequency content. This can happen when there is a large area of roughly the same color, such as darkness, or there's a lot of softness to the image, such as happens in a blurry photo. JPEG hates sharp edges and will have to spend more bits to avoid damaging them too severely.

Here are some stats on file sizes for a set of 133 high-res 4:3 photos I took:

• Min: 8.52MB
• Max: 14.96MB
• Median: 12.55MB
• Average: 12.94MB

16:9 images will be somewhat smaller than this, as they are only 33.5MP compared to 4:3's 38MP.

Open the file in Nokia pro camera then in the menu choose picture info. You should see at least 10MB
