What are the best tips for improving the quality of blurry or pixelated images for content?

Resizing high-resolution images to lower resolutions required by online platforms like Amazon can result in unwanted blurriness or pixelation.

Properly resizing and recompressing these images is crucial to maintain quality.

AI-powered image enhancement tools like Pixlr, Fotor, and can use advanced algorithms to "depixelate" or "unpixelate" low-quality images, effectively improving resolution, clarity, and detail without losing quality.

The human eye can detect image quality differences up to around 300 dpi (dots per inch).

Anything higher than that provides diminishing returns in perceived sharpness.

JPEG image compression works by removing high-frequency information that the human eye is less sensitive to.

Excessive JPEG compression can lead to noticeable artifacts and blurriness.

Upscaling low-resolution images using bicubic or Lanczos3 interpolation algorithms can help increase pixel count without introducing new artifacts, unlike simpler methods like nearest-neighbor.

Sharpening filters in image editing software work by increasing the contrast at edges, which can help compensate for blurriness caused by downscaling or compression.

Sensor size and lens quality play a significant role in the inherent sharpness of digital photos.

Larger sensors and higher-quality lenses typically produce sharper images with less distortion.

Camera shake during long exposures is a common cause of blurry images.

Using a tripod or faster shutter speeds can help minimize this effect.

Chromatic aberration, or color fringing, can introduce noticeable blurriness around high-contrast edges.

Lens corrections in post-processing can help reduce this issue.

Shooting in RAW format instead of JPEG can provide more flexibility in post-processing to recover detail and reduce artifacts, as RAW files contain uncompressed image data.

Overcompression of videos for online platforms can lead to significant quality loss and pixelation.

Ensuring the correct video encoding settings is crucial for maintaining sharpness.

Increasing the viewing distance or screen size can make lower-resolution images appear sharper, as the human eye is less sensitive to individual pixels at a distance.

AI-powered "super-resolution" techniques, such as those used in Topaz Labs' Gigapixel AI, can intelligently upscale low-resolution images while preserving fine details.

The Bayer filter in most digital cameras can introduce moiré patterns and artifacts, which can be mitigated by using a dedicated anti-aliasing filter in front of the camera sensor.

Sensor dust and scratches on camera lenses can contribute to overall image softness and haze.

Keeping equipment clean and well-maintained is essential for optimal image quality.

The choice of file format can impact image quality, with lossless formats like PNG often preserving more detail than compressed formats like JPEG, especially for graphics with text or illustrations.

Shooting in overcast or diffused lighting conditions can help reduce the appearance of haze and improve overall image sharpness, as direct sunlight can introduce unwanted glare and reflections.

Adjusting the sharpness, noise reduction, and other image processing settings in camera can help optimize the in-camera processing for sharper, cleaner results, reducing the need for post-processing.

The use of specialized optics, such as macro lenses or teleconverters, can introduce unique distortions and aberrations that may require careful post-processing to correct and maintain image quality.

Emerging technologies like computational photography, which combine multiple exposures or use machine learning, are enabling new methods for enhancing image quality and reducing artifacts in post-processing.
