Ideally, your image should have the best brightness, contrast and colour aspect. Unfortunately, it frequently occurs that some processing is required to show particular images in the best way. This requires processing in dedicated image editors, whether free such as Gimp, Krita, or paid, as Adobe Photoshop. Simple processing is best used with non-commercial applications as such operations do not require expensive software and it is better to be aware of general editing principles rather than a single approach to fixing. | Ideally, your image should have the best brightness, contrast and colour aspect.

Keep in mind that it is always less suitable to post process pictures than to have good ones from the start. Most pictures will probably end up underexposed, or darker than they should. This requires an auto-brightness adjustment or a manual one, applied with care to not leave any part of the picture overblown or unrealistically bright. On too bright or washed-out pictures, you reduce the brightness slightly to reduce the impact of too harsh light cast on different areas. | <code>''Keep processing to a minimum and use sparingly brightness and contrast adjustments. If your software has auto settings, try to use them for quick results that do not end in hard to understand solutions. Experiment as much as possible with different settings to improve your skills and learn to compensate for your camera's shortcomings''</code> | ||
===Brightness adjustments=== | |||
Keep in mind that it is always less suitable to post process pictures than to have good ones from the start. Most pictures will probably end up underexposed, or darker than they should. This requires an auto-brightness adjustment or a manual one, applied with care to not leave any part of the picture overblown or unrealistically bright. On too bright or washed-out pictures, you reduce the brightness slightly to reduce the impact of too harsh light cast on different areas. | |||
<code>''The most likely operation is brightness adjustments, most likely in an attempt to lighten rather than darken an image. Make small adsjustments and evaluate carefully the before and after effects. Always keep the original image for reference and future use.''</code> | |||
===Contrast adjustments=== | |||
It is advisable to control brightness and contrast at the same time, and try to increase contrast slightly when making editing. Keep in mind that too much contrast accentuates in a unrealistic way the picture and it is not preferable. Slightly increasing contrast and light by low amounts, in the range of 5-10% generally ends up with slightly more appealing pictures. To have a good grasp of the result, always compare your initial picture with the resulting one at different values, and note which one ends up with the best compromise. | It is advisable to control brightness and contrast at the same time, and try to increase contrast slightly when making editing.

<code>''Contrast adjustment can artificially make a picture more appealing while it can also lead to an artificial look if overdone. Adjust as little as possible contrast or leave it unchanged to avoid loosing more subtle details in your picture.''</code> | |||
===Saturation adjustments=== | |||
Saturation adjustments are even more difficult to carry and more subjective. As a rule of thumb, you avoid overly bright or intense colours or ones that are way too subdued. However, always take note that increasing saturation also increases the chance of various artifacts and unwanted parts of the picture to stick out much more than you would like. This is why saturation should be generally left as is. As a rule of thumb, when increasing brightness in a picture, you can slightly bump saturation by a few percents to avoid an overly drab image. | Saturation adjustments are even more difficult to carry and more subjective.
