Recently I took a 1GB memory chip from a Sony DSC W80 to Walgreen and
they transferred the images to two cds. The camera is new so I am not
in tune with all the options etc. Looking at the images, on my
computer, the landscape pictures seems not as sharp as I expected (?).
My question is when I take a chip and get a CD do I lose some of the
sharpness. Pictures were 7 MP. If not it must be me or the camera?.
Thanks in Advance




Copying won't change the quality, and why don't you just copy to hard
drive then burn to CD/DVD yourself? Can't tell if it's the camera or
photographer until (hopefully) seeing what the photos look like.




Many labs create CDs that are only 1800 x 1200 regardless of orginal file
size.

Some quick calculations tell me if the lab only give 2.16 MP Iam losing almost 5 MP that seems like alot to me. I would sure would like to find out who not to go to. I believe the equipment that Walgreen was using was fuji (sic!). I was looking at a typical picture the specs are 3072 X 2304 (~7 MP) with 24 bit color (16.7 M). Interesting that my computer says the file size is 2.4MB but (7 MP X 24 bit color)/8= 21 MB ?????. What am I missing here.


What you are missing is jpeg compression - often about 10 to one on
digital cameras - so 2.4mb might be about right. Have you ever read them
into a computer to see how big they are? Or calculated an average size
from what you fit on a memory card? Or checked manufacturers specs to see
what they say is a nominal file size? You have to know what you're
starting with before you can tell what they are doing.




The reason for using Walgreen was the photosoftware with the camera is not capable with my computers OS, in addition my memory card reader does not support 1GB memory card. I have not verified that but I will!. It seems, and this is very prilimary, that landscape on the subject camera may not be as good as others which I am more than ready to listen to. This camera is for my wife who is not a photo person but on vactions and other events she wants to take her own photos but is should be compact and no interchagable lens. Again thanks for any words of wisdom.



Bingo...I forgot the pictures in this Sony are JPEG. That may account for why landscape pictures (like mountains in Colorado ) do not appears as sharp as I would like. Since JPEG is a compression process pictures do suffer somewhat (but not very much for most picture takers). Yet, compression may
the reason that landscape pictures appear alittle dull. This does not appear to be the issues for pictures taken at much shorter ranges e.g., parking lot or people setting at tables (with camera not in landscape mode).?
