I'm a big proponent of standing. It makes stepping back much easier, and subjectively I feel more engaged in the work—something like boxing or dancing with the piece. At the same time, I also have terrible back problems, so both standing or sitting for long periods hurts my back. So I need to alternate between standing and sitting frequently. So, I use a high stool, so when I sit on it I'm at the same height as when I'm standing, and it's a stool so it's easy to get on and off. However, I know lots of people who work sitting down, whether it's for artistic or ergonomic reasons. Stepping back is really critical to regaining objectivity when looking at your own piece. However, it's not the only way. There are other techniques, all of which have a common theme: shifting your perspective. In other words, look at your piece in a different way. Here are some ways to do that: - Stepping back is the easiest technique in many ways, since it's fast and doesn't require any extra equipment. - Looking in a mirror is another great option, since it increases the effective distance and also flips horizontally. But it requires a mirror and I often find it hard to juggle. I believe I saw somewhere that James Gurney rigged a mirror system so he could just glance quickly without having to hold anything. If set up right, this could be even faster than stepping back. And mirrors are a great option if you need to sit or have limited space. Looking in the mirror doubles the distance you see your piece from. - Taking a break is maybe the most effective option of all. I consider this shifting your perspective in time. Something about seeing your work after a break makes tons of stuff clear. But of course, this one requires time. And it seems the longer the break the more clearly you'll see your piece. But even a short break is helpful, and I'd even say it's critical. - Taking a photo of your piece. Something about seeing it on a screen can make things stand out. - Squinting shrinks the value range and softens edges. - Turning your piece on its side or flipping it over. I personally haven't had a lot of success with this one, but I know of several amazing artists who swear by it. - Asking someone else is also super important. It gives you their perspective and helps shift yours. Once someone points something out it becomes obvious. Of course it's great to get feedback from teachers and people more skilled than you. But getting people of similar level—and even people with less or no experience at all—can give you helpful data and shift your viewpoint as well.
