Photography Tip: Straighten Up Your Photos

Keep buildings going up and down and bridges going side to side. Here is why a straight horizon is one of the simplest ways to take better photos.

One of the simplest ways to take better photos is to hold your camera straight: keep buildings going up and down and bridges going side to side. A tilted photo makes the viewer feel seasick. I’m Katie Donnelly, a Paris photographer, and this one really gets to me.

That Tilted Commercial

The other day I was relaxing at home after a crazy day- Grilled chicken and avocado sandwich in hand for dinner, cat snuggling with me on the couch and I flip on the TV.

There it was again.

That Sensodyne commercial.

You know the one I’m talking about- You’re in a dentists office and they’re talking about 9 out of 10 dentists recommending Sensodyne for healthy gums. Oh yeah, and the camera is always tilted in a weird way so it looks like the dentist is about to fall off the earth.

I can’t stand it.

Every time I see the commercial I get angry. IT LOOKS BAD. Seriously, these guys are paying a lot of money for a commercial that looks like it’s straight out of the 80s and shot with the intention to make you sea sick.

I think to myself, “Why can’t they straighten the camera? WHY!?”

We all do it, not holding the camera straight by accident and then BOOM, buildings are more slanted than usual, but a whole commercial!?

Straighten Up Your Photos

Okay, enough of your rant Katie. What I’m trying to say is STRAIGHTEN UP. Your photos, that is.

Keep buildings going up and down and bridges going side to side in your photos.

Don’t make the viewer seasick… Or want to change the channel.

YES!

How to Keep Your Photos Straight

  • Turn on the grid in your camera or phone and line the horizon up with it.
  • Check the edges of the frame: buildings, door frames and lamp posts should be vertical.
  • If it still comes out crooked, use the straighten tool when you edit.

PS just to say I love Sensodyne just not their commercials. We buy it all the time.

Questions About Straightening Photos

Why do my photos look tilted?

You were not holding the camera level. It happens to all of us by accident, and buildings end up more slanted than usual.

How do I keep the horizon straight?

Turn on the grid in your camera or phone and line up the horizon, or a building edge, with one of the lines.

Can I straighten a photo afterwards?

Yes, most editing apps have a straighten tool, though you lose a little of the edges. It is better to get it straight in camera.
