Nikon or Canon Entry SLR, which is suitable for shooting scenery?

Nikon's white balance is better than Canon's, so I recommend Nikon as an entry machine. (mainly shooting scenery). Canon is more suitable for shooting people. Canon's autofocus and snap focus are better than Nikon's, and it's easy to capture objects and play them in focus when in continuous shooting. Therefore, most of the long guns and short guns in various sports competitions are Canon's (you can go to a competition for textual research).

In addition, the larger the aperture, the shallower the depth of field (which can blur the background), and the smaller the aperture, the deeper the depth of field (which can make the background clearer). A very simple but important application is to illuminate the landscape with a small aperture and a deep depth of field, like a still life with a large aperture and a shallow depth of field. This is worth recommending to you.

D3000 is recommended for entry machine. D5000 or Pentax can be considered if possible. Pentax is very popular as an entry machine. If you really want to buy a Canon, you can consider D60 or 500D. After all, it's just an introduction, and hanging a dog's head is enough for you to achieve something small.
