TIFF or JPEG

[rescue902]

Hello,

This is my first time scanning my slides onto a CD through A and I

and I was hoping to find out if I should have them as a TIFF format

or JPEG, are there any pros or cons? Will the file type affect what

I can do with them? What is the best for overall viewing quality?

Thanks,

Jason

Anything is wrong. TIFFs are huge and need good computers for viewing. JPEGs loose quality with every re-saving after a manipulation. I'd say start with TIFF and end with JPEG.

Use both. Save the original as a TIFF at whatever resolution you use and then set to read-only. That way you always have the original, which can't be altered unless you want to make changes. Then when you have enough, save them to a CD.

 

Then for Web viewing or for taking to a photo shop, resize to the correct DPI and save as a JPG.

 

You can't display a TIFF in a Web browser without some type of plug-in. However, TIFF will give you the best quality image.

 

For Web display, JPG makes sense because it's compressable. It uses "lossy" compression, which means you do lose quality. TIFF is "loss-less" compression.

 

And for Web display, aim for a maximum file size of 80k-120k. If it takes forever for someone to download the photo, then the "fun" factor will be very low.

Burn whatever you shoot to a CD without any image adjustment whatsoever. In 10 years maybe there will be a way to get the perfect image out of the unedited originals. I saved all my overexposed negatives then one day someone invented an inexpensive negative scanner and I recovered my work!

Don't bother with anything less than a 16 bit per pixel Tiff. 8 bit TIFFs have little quality

advantage over JPGs, but take up much more space.
