Hi need to ask a question regarding develoment at conventional shop, normally sent in the mem card or crop and save in cdrw. Due to at the moment only had 1 mem card, if sent in the card then will be without mem card to shoot during the processing time. And if save in cdrw will the quality of the picture be affected, can any guru answer my doubt thank you.

Usually, I saved the photos I want in CDR, and bring it down to my one preferred kodak express shop in Yishun. They take the cdr, anc copy onto their computer, and I collect the photos the next day. I am happy with the results so far. I only do this when I need 4R. For A4, I do my own printing.

Why don;t you do a check with your shop. They could allow you to transfer your image from your memory card to their PC, and do the processing from there.

As far as I know, only JPEG is accepted. And you don't have to leave the memory card at the store, right? I develop my photos at Kodak Centres and all you have to do is transfer the shots to their specialised PC and collect the next day (or 1 hr but double the price).

And transfer to CDRW will not degrade photo quality. It's just another medium, just like your mem card.

Just send it in via CDR and forget about it.

Haha this is the 1st time I'm hearing this... will saving digital images to a CDR degrade image quality? :bigeyes:

OMG what do you think? When you save a word document to a CDR, will the integrity of the text be affected?

Pai seh hijack this thread, another newbie ques :embrass:

If i scale down the resolution to 1024X768 and send it for developing, it wouldn't affect the quality for 4Rs print right?

If you scale down then it WILL affect quality. Your pixels/inch count will go down and you'll see obvious pixelation.

Always send as big a resolution as you can get for printing.

I heard people was saying that if you send your picture file online to printing centre the quality will be affected, that why i am wondering how about cdrw will affect the quality. But anyway all the precious information are welcome, thank you.

Thanks for your info. :thumbsup:

Had this habbit of scaling down so it's more convinent to email or uplaod to web, and juz send the scaled down pics for prints. :mad2:

Really? Never heard of this. Anyone faced this problem before? Unless they scale down your images before they save it to their server...hmmm

For Digital Camera I am new so I am not sure, but for Audio Visual a single cable may affect your veiwing pleasure especially high end cable can cause thousand of dollar. And burning of picture into cdr I think it will affect the picture quality due to quality of the burner and cdr, especially the EMI noise from you PC worst if without a good power filter for PC to reduce the EMI noise from a normal power socket.

Audio and visual products generally use analogue signals which are affected by the quality of your cables. Digital signals are not affected by medium. A poor quality cable will affect transmission speed, but the integrity of the data stays the same if it reaches the destination. Either the data reaches its destination, or it doesn't.

If you feel that burning a digital image file on a CDR will degrade image quality due to EMI or EMP or Radiation in the air or pollutants in the air between your disk and the laser head, then so be it. I Surrender.
:sweat:

It may reach in the end however some data may lost during transmit in the end the picture quality will be affected more or less I guess so.

Then what abt the transfer to your memory card? By your reasoning, it's the same thing, no?

They will be no loss of quality as the data burned is digital like what solarii said. You will not be getting missing data unless your cdwriter is spoilt.

The more it transfer the more it will degrade the quality, same as Audio CD when you copy from the original the duplicate copy quality is not as good as the original copy, it same applied to DVD as well. This is for sure as I had tested and proven with it.

Hi, just want to offer my $0.02.

Audio CDs and Data CDs are different.

Data CDs contain error checking mechanisms such that the drive is able to verify that the data being read is correct. If not, it will try to re-read until correct. For audio CDs, there isn't this extra error checking. That's why there exists software such as ExactAudioCopy to make exact copies of audio CDs.

From http://electronics.howstuffworks.com/cd7.htm
Because the laser may misread a bump, there need to be error-correcting codes to handle single-bit errors. To solve this problem, extra data bits are added that allow the drive to detect single-bit errors and correct them.

If a few bytes are misread in music, the worst thing that can happen is a little fuzz during playback. When data is stored on a CD, however, any data error is catastrophic. Therefore, additional error correction codes are used when storing data on a CD-ROM.
From http://www.vochor.com/cd_playability.html
The audio format is problematic in this digital era due to its original design over 25 years ago. Computer CD players and burners have been designed for high-quality reading and recording of data CDs. Data CDs are quite different from audio CDs. When a data CD is written, checksum (CRC) codes are written along with the data so that when the data is read, the checksum from the actual data can be compared to the original checksum "on the fly." If the checksums differ, the CD can be reread many times until the correct data is finally obtained. This generally cannot be done with an audio CD. The audio format was originally intended to be a real-time format. Each bit is read off of the disk at the time it is needed to make up the audio waveform. There is no time to go back and reread a section of the disk - the music would stop!
