How to Size Images for Online Sharing
Whether you’re running a photography business, or sharing your photography on the web with friends, it’s important to know how to properly size your images for various uses. Generally speaking the smallest size you can share, while still retaining enough quality for the viewer to appreciate the photograph, is what you’ll want to aim for, but let’s dive into this with a bit more detail.
First rule – use the sRGB Color Space for anything going on the web
Before you even think about sizing an image for the web, you’re going to need to make sure that you’re using the
correct color space. The web is standardized on the sRGB color space, which means that if you want your photography to appear accurately across the web, that’s the color space you need to use when you save your image.
Take a look at this side by side comparison of the same photograph, saved directly from Lightroom, using the sRGB color space versus the AdobeRGB color space.
You’ll notice that the AdobeRGB color space appears slightly more muted in terms of color and it has a slightly more greenish tint when compared to the sRGB image.
Second rule – Smaller size over image quality
Even in this world of high resolution monitors, it’s still the best practice to use smaller sizes when sharing images on the web.
