I am working with a product photographer who is having issues understanding dpi and resolution.
She is shooting products to go onto a website using a Canon 5D and an ortery box.
I have asked her to provide three images for inclusion on the site; one at 720 pixels wide, one at 360 wide and a thumbnail at 60x60.
The issue is that Lightroom, which she is using for post processing, is forcing her to choose a width and reducing the quality of the image too far.
We need to balance quality with image size. For the 720s, an image around 500k is fine and should have enough resolution to allow users to zoom in to see some detail.
What’s the best way for her to convert the jpegs to 720 wide and maintain enough resolution for zooming?
Here's the image used on the actual website It's the last of the thumbnails. Be sure to mouse over the image to see the magnifier.
The goal is for users to be able to read small numbers on the products while maintaining a reasonable file size (500k?).
