The presets themselves do not change the inherent quality of the image, but they can significantly enhance the appearance and aesthetic of your photos. By adjusting various settings such as exposure, contrast, and color balance, presets can bring out the best features of your images and create a more polished, professional look.
For example, if you have a photo that appears slightly underexposed, applying a preset can instantly brighten the image, revealing details that were previously hidden in the shadows. Similarly, a photo with dull colors can be transformed by a preset that boosts saturation and vibrancy, making the scene appear more lively and eye-catching.
In essence, while presets don't directly alter the image's quality, they can greatly improve the visual appeal of your photos, making them more engaging and attractive.
