３点の通過だが、カラーで撮ったものがダメ。
This file contains artifacting when viewed at full size. This technical issue is commonly created by the quality settings in-camera or in post-processing.
· Always save images at 100% quality

· Some images have too high levels of noise to be corrected by noise filters/programs
· The higher the ISO setting the more light needed to avoid noise
· Some post editing programs can create noise once resaved
· Every part of a photo needs a different amount of adjusting to get rid of noise, etc.
· Post edit images in TIFF (or PSD) format to avoid compression
