No matter how good a photographer you are, there are a number of “little” flaws, sometimes beyond your control, that could completely spoil your photography. Sometimes they are imperceptible errors, but depending on who is looking at your photos, they can affect the professionalism of your work.
In your efforts to get decent photos, the lens or camera itself can play a bad trick on it. In today’s article, I’ll highlight 3 of these small bugs, how they negatively affect your photos, and how to avoid them.
- I suppose you already know (and if I don’t tell you) that in low light situations it is advisable to change the settings of your camera (be it a DSLR or a compact.
- This is not important) by increasing the ISO sensitivity.
- This allows the camera to capture more light and therefore gives us a brighter photo.
- The downside (yes.
- Everything has a price) is that in return the camera puts a little “noise” in the photo.
- Noise is the kind of small dots that usually appear in the darkest areas of the photo (here’s an example).
- In general.
- The higher the ISO.
- The more noise there is.
- As the example image shows.
- Not all cameras produce the same amount of noise at the same ISO level.
- For example.
- The Nikon D60 starts to show noise in photos when it reaches around ISO 562.
- On the Nikon D3100.
- We get some noise that reaches ISO 919.
- On the Canon 5D Mark II we can reach ISO 1.
- 815 without feeling any noise yet.
- And on the Nikon D7000 up to ISO 1.
- 167 we can still be calm.
- Don’t ask me about the maximum ISO value your camera can reach without worrying about noise because I don’t know.
- But in theory the more advanced the camera and the more “professional” the better the ISO handling.
- How to avoid annoying ISO noise? Either researching specialized websites where they usually mention the maximum ISO value of each camera in which considerable noise does not appear yet.
- Or experimenting with your camera yourself and observing its limit.
Chromatic aberration occurs when subjects and photographed objects are surrounded by blue on one side and red on the other. To make you understand me, look at this example on the right (click to enlarge). As you can see on the back of the shirt, you can clearly distinguish a red line, while on the bottom edge of the shirt we can see a kind of blue line.
In fact, this error is caused by the target (have you ever wondered why some targets are cheaper than others?), and tends to occur more at the edges of the image than in the center. There are two ways to avoid this failure in our photos, one is prevention and it is simply equip ourselves, whenever we can, with the best goals. The reason that two equally expensive targets sometimes cost twice the price of the other is the quality of the crystals and optics they use. The other way to avoid this failure is to apply a subsequent “orthorect” process that can be performed with the help of a photo editing program like Adobe Photoshop.
Some lenses, especially wide-angle lenses, produce a side effect of distorting the perspective and proportions of the photographed frame. Here are two examples where you can see that the statue and the old house are slightly tilted to one side. simple optical effect of the lens (I think I photographed them with a lens of about 14 mm).
It must be said that many times this distortion of perspective is something sought after, a mistake on purpose, because it does not cease to have its aesthetics, in some situations we may want to look for this distortion, for example to do something huge or great. However, if we do not seek it deliberately it is advisable to use this type of lenses (I would say 10 to 18 mm) with some caution, there are still methods to correct such distortions later using Photoshop or another editing and post-processing program.
Of course, the list of small mistakes that your photographic team can make for you is longer, this time I wanted to share with you the 3 most common, I hope you liked today’s post. I’ll try to talk to you about other mistakes like this in the future.
