It’s been a long time, I just sit beside my window and take so many pictures as same angle as this one. and put it into the DPP application to see how clear the resolutions are.

It’s interesting to see how definite the mosaic tile is, when viewing the original size, and moire is visible or not, should I apply the noise reduction or not.

But once you convert and saved an image, there are always something different. some image quality only exist in a certain application and raw file.
