Resizing Pictures

[Steve Pl]

I am just getting started in the digital picture arena and I have a processing question.

My camera, Canon A620, is a 7 meg, jpeg only files. I have looked at some work flows but have a question on resizing. What/Why is this process being done? My jpegs are 3072 x 2304. What would they be resized too? My main focus right now are 4 x 6, 5 x 7, and the occassional 8 x 10.

After processing is there a benefit to saving as a Tif or should I just stay in jpeg?

Thanks for any answers, I am sure there will be more as I dig into this.

I personally never resize anything when doing hard-copy printing. The only resizing I do is when uploading to the web (you don't want people to have to download a 5MB image 3000+ pixels wide and then scroll from edge to edge just to see it), or when sending a CD-ROM of photos and I don't want the recipient to have the full-resolution files (image theft).

TIFF or JPEG? Again, it depends on how serious/meticulous you are with your photos--and what purpose you're planning for them. If you're only using them for smallish prints for family and friends, then JPEG is fine. TIFF will give you an uncompressed file for fewest artifacts if you are planning on huge enlargements.

You don't really gain much by turning a JPEG into a TIFF. Just a larger lossless file (it's not like you are going to gain any colour depth etc).

If you had a RAW file to begin with it would obviously be a different story.

One advantage of converting to TIFF is if your doing a lot of editing and want to save often. Each save in JPEG looses more dtail.
