Almost everyone who edits photos and graphics in Photoshop uses guidelines. You can easily drag these from the ruler into the image and use them to align certain image elements. You can also display different dimensions on the ruler (double-click on the ruler) to measure sizes or distances. Centimeters, pixels or inches are most commonly used. However, since the last feature update, Photoshop no longer displays rulers on some computers.
The key shortcut Ctrl+R / Cmd+R, with which Photoshop shows or hides rulers, and using the View menu do not work either. If you press it, however, the image position changes marginally – something is obviously happening. If you aim accurately, you can even drag guidelines out of nowhere. However, this half-solution is not satisfactory.
After a customer asked me about this problem, I started looking for a solution. Read on …
More than 10 years ago, for most photo amateurs photography was limited to special occasions, but today it accompanies us in all parts of our lives. Thanks to the rapid development of smartphones and the resulting images. Pretty much everyone carries such a small wonder flounder in their pocket or handbag. And many make diligent use of the built-in photo app because it seems fun to capture dinner, puppies playing, the view out of the hotel room window or a pop concert and at the same time share this experience with the whole world. Not even dangerous superficial knowledge plays a role – and picture quality certainly doesn’t, too.
For many years, zoom lenses in the lower price segment were considered tourist stuff. Dad went on vacation with his new SLR camera and two zoom lenses and was able to easily capture all the family’s holiday scenes on film or slides. This worked reasonably well as long as the photos weren’t substantially enlarged. Otherwise the weaknesses of these inexpensive lenses became noticeable. The question of zoom lens or prime lens did not come up for professionals. For near distance images they photographed almost exclusively with prime lenses, only for distant scenes they chose – mostly for cost and weight reasons – professional zooms.
You might think that pros only shoot great photos and never miss their subject. But you are wrong about that. Because bad real estate photos are simply not shown.
