What is compressed? I dont understand. Is it noise? This time most of my shots are quite noisy I cannot push so much for most of the pictures.
I have to go sleep now. Tomorrow morning go to school. Good night and thank you.
hi,
if you look at your third picture posted (the warmer one), at the end of the pontoon on the left, in the water, there is distinct pixellation. this is more than likely because of your small file size (45kb). if you know how jpg compression works, this is the result of high jpg compression... i.e. details being shoved together, resulting in artefacts.
you can read the wikipedia article on this here:
http://en.wikipedia.org/wiki/Compression_artifact
hope this helps.
i find that for most landscapes, due to the huge amount of detail retained and required for presentation, i try to keep it to around 250kb. you can control this by resizing to the required posting size (instead of relying on what flickr/facebook suggests), and then save to web, and adjust the quality from there to hit 250kb. you will more than likely avoid such artefacts with such a file size limit placed.
