We get emails now and again from puzzled photo buyers about image resolutions at Cutcaster and what size photos they need for their specific project now that we offer different image resolutions at Cutcaster. Photo resolution has to be one of the most confusing and misunderstood aspects of digital image editing. Photo resolution only matters if you're going to print the image in a book or magazine for example. If you are only going to use the photo online, you should focus your attention on the pixel dimension. At any resolution, you can measure the pixel widths and heights. It’s important to be very careful though how you change it. In order to best protect yourself, open the Image Size dialog in Photoshop and "uncheck" the Resample Image check-box at the bottom left. This has the effect of locking the pixel data, thus locking in quality. This is where it can be kind of confusing because the onscreen image won’t change at all and you can only see the truth by opening the Image Size dialogue box. If you have any question about photo resolutions or pixel dimensions, please leave a comment below or email help AT cutcaster DOT com.
