Image size and compression

[Bob Riggins]

I am about to go to Italy and was looking at my camera setups.

When the camera compresses the picture to save space, it discards picture data, which causes the quality of the picture to degrade. There is no way to recover the data. You may be ok if you are only going to put the pictures on the web or printing a small print. But if you want to crop the picture or print a larger print, you may not have enough data left to do so. On a trip to Italy, the price of memory today, I wouldn’t take the chance. I always have my camera set for the highest possible quality, in fact, if your camera will shoot RAW, I would recommend it, for anything more than a snapshot.

Yup, flyfishertoo nailed it…

Always capture as much info as possible with your images and leave your self as many options as possible for post-processing.

6mb is massive???

When I convert my raw files to tiffs at 200 percent in PS, they are 143.5mb in 16-bit mode!

Photoshop is the easiest way to resize your images.

[stillshootingfilm]

no, your’e right. not that big if you’re going to save and print.

For email and posting to the web, I generally resize mine using Photoshop to 72 dpi (I have read that this can be almost any number, but 72 is what most use) and change the size of the picture to 800 pixels on the longest side. I then save as a jpg with a quality setting of about 7. This makes the files small enough that you can email several of them, yet retains enough quality that they still look good when viewed
