Question about a 90mm fuji lens on a Wisner 4 x 5

[ndwgolf]

Hi guys
When using a 90mm wide angle lens on a LF camera shooting a landscape with a model on the shot does the lens tend to distort making the model look fat??

Reason for the question I am planning to shoot a pretty model in some paddy fields so I not only want the model in the shot but I also want the landscape in as well......hopefully not making her look fat

Thanks

Neil

thats a strangely phrased question......

a 90mm on 5x4 will look similiar to a 28mm on 135 format. give or take a bit for the different aspect ratio.

If your lens is good it will not distort. A lens that distorts is either poorly designed or defective.

That being said you are asking about using a wide angle you will be faced with an effect of optical physics called foreshortening. That means that objects closer to the lens will appear larger then objects further from the lens. The longer the lens the less of an issue this becomes.
So, if you want to use a 90 on 45 for environmental portiture there are things you should do, move the subject further from the lens and turn them so you are not shooting them directly on.

Thanks Bob,
When you say further are we looking at 10 or 20 feet for example??

Yea Ive got that bit....when shooting my Leica S with a 30mm (~24mm in 135) I have to be very carful the lens is level or it make my wife look fat and that means no dinner or p***** for the rest of the week

20 should be good.

You should also be aware of perspective distortion, as opposed to lens distortion. The closer the model is to the camera the greater the perspective distortion. Typical phone selfies have high perspective distortion with their ~28mm equiv. lenses at arm's length. Position your model at least 10-15 feet away for best results.

Perspective is controlled by the angle of the camera to the subject. What you are talking about is foreshortening.

Okay so I will get my wife to stand ~15 feet away and also have her sideways on...........that will work. Will I also be able to use front tilt to try and get the front middle and far in focus??
