Canon 7D and 55-250 lenses. How to take a good picture of the moon with B-door mode, set parameters and tripod?

Canon 7D plus 55-250 lens can shoot the moon. But you can't shoot with door B. As for "scenery parameters", it is a vague concept and can't be used directly.

First, talk about the equipment itself. ...

7D is a flagship half-width SLR camera with excellent performance. It's no problem to shoot the moon with it.

55-250 lens, the grade is average, the performance is average, but the picture quality is ok, and shooting the moon is competent. ...

But the biggest problem with this configuration is that the focal length of the lens is not long enough, and the moon will be smaller ... Generally speaking, shooting the moon requires at least 600mm physical focal length ... The telephoto focal length of …250mm is shorter ... so I can only cope.

Secondly, talk about shooting parameters. ...

There is definitely no B-door ... B-door is a long exposure mode. Moreover, it doesn't take long exposure to shoot the moon ... If you shoot with door B, you can only shoot a bright white, and you can't shoot a good photo of the moon at all.

As for "scenery parameters", it is a completely vague concept ... maybe this is the creative effect of some kind of camera ... but it is not suitable for shooting the moon.

Set the parameters of shooting the moon, use spot metering and low sensitivity ... and then set the appropriate aperture and shutter according to the specific situation, so as to shoot well. ...
