I replaced my Nikon P90 for interior work photos with a D5500 for better light control without flash. That is working fine, but when I resize for the Web my photos are 500×334 instead of 500×375 — which my website is set up to accept. Why?
The sensor ratio are different:
When resizing your images, you are probably fixing the length of the longest dimension of your image to 500 pixels, and the shortest dimension is computed accordingly.
- On the P90, it yields 500*375 pixels images (500/375 = 4/3)
- On the D5500, it yields 500*334 pixels images (500/333 = 3/2)
You need to crop the D5500 images using a 4/3 image ratio.
