Perspective is important in capturing the best-looking apartment photos. Perhaps landlords have seen some real deal photographers in action, say at a wedding or a professional apartment photo shoot, and they noticed the pros will use a ladder to get more dimension or a wider scope for their shot. This is a great tactic IF you have the right lens, flash, and a host of other professional equipment to complement the added height.
Avoid shots that look like they're taken perched from the top of a ladder (or those taken way down low from the perspective or a housepet) when it comes to DIY smartphone photos. Unless you are using a stable chair or stepladder to get that added height, then you're usually hoisting their camera high up into the air and hoping for a great shot. This is like shooting photos blindly, in other words. And stretching those hands as far up as they can go will be less stable, resulting in blurry or out-of-focus images in the end.
Don't go for fancy tricks or gimmicks. Instead, get your framing right by standing with your feet shoulder's width apart, holding the camera at eye level (with both hands) and aiming for a neatly composed frame. Use the grid feature of the smartphone app to line up the photos.
Once you've taken a couple of snapshots, decide whether or not you're using the best orientation for your apartment photos. What does that mean? Rotating the camera 90 degrees will result in wider, landscape orientation photos. Leaving the smartphone upright in your hands will produce vertical, or portrait orientation, images. If the apartment has a lot of space that you want to showcase in the photos, then stick with the landscape (horizontal) orientation. If there are more specific details you're after, such as high-end fixtures or appliances, then consider using the portrait orientation (vertical) for the photos.
