Basic principles of photography post-processing

Achieving professional-looking photos through post-processing requires following some key principles. Here are basic principles to keep in mind that can help you elevate your images to perfection:

Avoid editing the original

One of the cardinal rules of photo editing is to never edit the original image. Instead, always make a copy of the original and work on that. This ensures that you have a backup in case something goes wrong during the editing process. Moreover, by preserving the original image, you can always revert back to it if you are not satisfied with the edits you have made.

Crop out unwanted parts

Cropping is a powerful tool in photo editing that allows you to remove unwanted elements or distractions from an image. When editing your photos, it is important to identify and crop out any unnecessary parts that do not contribute to the overall composition or narrative of the image. By doing so, you can create a cleaner and more focused visual representation.

Use proper resizing techniques

Resizing an image is often necessary to fit different platforms or printing requirements. However, it is crucial to retain the perspective and maintain the quality of the image when resizing.

Avoid stretching or distorting the image as it can result in a loss of detail and clarity. Instead, use proper resizing techniques that preserve the overall integrity and visual appeal of the photograph.

Do not over-edit

While post-processing can enhance your images, it’s important to avoid over-editing. Excessive use of filters, effects, or adjustments can make your photos appear unnatural and detract from the original scene. Aim for a balanced and subtle approach to maintain a realistic look.

Precisely adjust the contrast

Contrast is an essential element to consider when editing an image. Applying the right contrast to an image can make a huge difference in the visual impact and overall quality.

However, basic contrast adjustment tools can sometimes make an image appear too dark or washed out. Start by analyzing the tonal range of your image. Look for areas that appear too dark or too bright and adjust them accordingly.

This can be done by using tools such as levels or curve adjustments, which allow you to modify the brightness and contrast of specific tonal ranges. It is important to experiment with different levels of contrast adjustments to find the right balance for your image.

Ensure screen calibration

Adjusting the display settings of your screen is essential for accurate and consistent color reproduction when editing photos. Setting the brightness, contrast, color temperature, and gamma to match industry-standard color profiles will help you make precise adjustments to your images, and you will achieve more reliable results.

To calibrate your screen, you can use a hardware calibration device, which measures the color output of your screen and creates a custom color profile.

If you don’t have access to a hardware calibration device, you can use built-in calibration tools in your operating system that can help you adjust your screen settings manually.
