Guis (and girlies), I need your help

Either way you've been made to look a jackass by saying JPEG makes things blurry, which it doesn't, and Lossless JPEG is an operation mode of JPEG, making it part of JPEG. QED.

A mode of a compression algorithm != part of a file format?
To make that assertion is like saying since IEEE created the IEEE 802.11 wireless protocol, your old wireless B router is capable of running a wireless N network. :rolleyes:

JPEG compression as used within the JFIF file format, will result in some blurring whether perceivable by the human eye or not. The fact you cannot tell shows the compression algorithm works well. The fact its a lossy compression on the other hand is unaffected by that.

Not sure if this helps, however I remember my lecturer stating that JPEGS do tend to have less quality and are designs to save space which ultimately results in blurred vision compared to other formats.

Thats an OK layout, And I don't see any blur in the JPEG Image?

[Jam-ez]

If you got a large picture, or high quality picture, and converted it to jpg from png, you'd probably see the difference.

Okay, my digital camera takes photos in jpeg, its 10.1 mp and I cant see blur

I did this as part of my A Level Computing Course. The textbook states about JPEG that "some visual quality is lost in the process" so Mentor is correct.

Likewise.

As I said before, JPEG does not inheriently cause the image to be blury. However, under certain conditions the image may be blury.

We're not talking about it losing quality (Yes, it can lose image quality), just about if the image is blured or not.
