Image Quality

I have tried putting up pictures of all sizes, even as small as

600x800 pixels, and it looks like that your imaging software when it

displays on the portfolio doesn't reproduce it faithfully and there

is lot of noise.

Try to upload images whose size is slightly less than 800x600. They will appear "untouched" when you look at them. If you post large images, they are resized in the medium-size view, but they should be OK in the "LARGER" mode view.

I have been looking at some of your photos. They look fine to me on my laptop (1400x1050 pixel resolution).

 

Could you point to a particular image where you think ther's a lot of noise ?

 

Thanks

Cannot be any wider than 650 pixels. Otherwise compression will make a noticable, negative difference.

Vincent, what happened to <a href="http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=0095HK"> the 680 pixel </a> limit?

Thanks for quick response. I can see the noise in all pics. Even the larger ones. Have a look at:

E.g

http://www.photo.net/photo/2999646&size=lg "captioned partners at night" . In the original pic. I see distinct - 7-rays emanating from the light in tmy original picture. But the one uploaded don't show the sharpness at all. I am using IE-6.0 and screen resolution set to 1078x800

 

Thanks

680 wide, Peter is correct. Not sure why I said 650. Brain damage I guess.

 

Anil, there will always be some measure of j-peg compression artifacts anytime you upload. However, if the width is no more than 680 pixels, you will get as good a quality as is possible and equal to the quality we all have available. We all face these same issues.

In addition to the compression issue, the chroma-subsampling in your images is 2X2, which reduces the apparent quality of the lights (1X1 is better). I don't know if the PN servers are "buggy" again?

For much more info read my article on <a href="http://www.photo.net/learn/jpeg/index.html">Jpeg Compression</a> (http://www.photo.net/learn/jpeg/).

If you upload a photo that is too large for normal web display, the photo.net software creates a "Medium" view and displays this by default instead of your original uploaded photo. This will have smaller dimensions and will probably be more compressed than your upload. When such a "Medium" view is displayed, you can always view what the photographer actually uploaded by clicking "Larger", although this may be very large both in dimensions and bytes. But the "Larger" view is exactly what the photographer uploaded, untouched by any software on photo.net. If there is no "Larger" button, you are looking at exactly what the photographer uploaded, which wasn't too big, meaning that no "Medium" view was necessary.

 

So if you want to control exactly what the user sees by default, make the image less that 680 pixels in width. If you make it wider, a "medium" view will be created and that is what the viewer will see by default. Your original will still be accessible by clicking "Larger", but it won't be shown by default.

 

All of the above only applies to photos being uploaded now and for the past several months. Before that, a different system was in use, and the "Larger" view may also be the result of compressing what the photographer uploaded.
