My objective is to compare two photos of the same object at different resolutions and be able to tell how much more detail does the larger image contain than the smaller one.
The point of this is to find the minimal picture size or resolution at which the camera can preserve the maximum detail.
The manual procedure is the following.
- take a photo using the lowest resolution, then another at the max resolution,
- resize the small one to the same resolution as the bigger one and compare.
- if the bigger photo has more details then repeat using the next to the lowest resolution.
- if the images contain the same detail level then the image at the lowest resolution is the max detail level the camera can capture using the lowest resolution possible.
I wonder if this can be done using software or another easier procedure.
any help is really appreciated. thanks.
