Nikon D5200: Straighten Tilting Horizon Lines
If you have a knack for shooting with the camera slightly misaligned with respect to the horizon, your Nikon D5200 can help you straighten out. Photos like the one on the left in the figure often wind up crooked — in this case, everything tilts down toward the right corner of the frame. Your inability to shoot straight might make you especially fond of the Straighten tool on the Retouch menu. With this filter, you can rotate tilting horizons back to the proper angle, as shown in the right image in the figure.
To achieve this rotation magic, the camera must crop your image and then enlarge the remaining area — that’s why the after photo contains slightly less subject matter than the original. (The same cropping occurs if you make this kind of change in a photo editor.) The camera updates the display as you rotate the photo so that you can get an idea of how much of the original scene may be lost.
Here’s how to put the tool to work:
Display the photo in Single-Image playback mode and then press OK to get to the Retouch menu.
Highlight Straighten, as shown on the left in this figure, and press OK.
You see a screen similar to the one on the right in the figure, with a grid superimposed on your photo to serve as an alignment aid.Press the Multi Selector right or left to rotate the image in increments of .25 degrees.
To rotate the picture clockwise, press the Multi Selector right.
Each press spins the picture by about .25 degrees. You can achieve a maximum rotation of five degrees. The yellow pointer on the little scale under the photo shows you the current amount of rotation.
To rotate the picture counterclockwise, press the Multi Selector left.
When things are no longer off-kilter, press OK to create your retouched copy.
