How do I adjust the render view to Include more rather than less?

Being vexed by something I have never noticed i had problems with even after over a decade of rendering but do have a problem with now. When I am setting up a render of a scene, I sometimes have to zoom out and adjust the aspect ratio to include everything in the scene that I want. However, widening the aspect ratio (say from 1:1 to 5:3) always seems to include more of the scenery from side to side but often at the expense of what is at the top and bottom. This can be annoying when i want to make a picture with a 1:1 aspect ratio but causes me to zoom into the scene in question too closely to get to the sides, or so far away I get blocked by a wall or some other object in the way. I can't seem to figure out how to change this. I hope I'm explaining this correctly, but does anyone know how to adjust the aspect raio of a scene *without* having to change the POV at the same time to force me to see that scene from a different distance? There *must* be a way, but stupid me cannot seem to find it!

    Not sure if that is what you are after.

    But have you tried to go to Parameters > Camera and decrease 'Focal Legth'? Default is 65, so you could try 30.

    If you're like me, you might want to read up on photography composition, because I am forever trying to cram too much into a scene.

    I actually have quite a bit of experience in photographic composition, and basically I am trying to make DAZ do the same thing with a scene as I can do with a good camera. Many of my pics are meant to be illustrations for stories that I also write, so I guess I am trying to get the most advantage out of the old saying "a picture is worth a thousand wprds". You are right about one thing thoug; I probably DO try to cvram too much into one scene. But usually I am very good at making it work for me anyway. It's just the aspect ratio problem I have apparently forgotten how to deal with that has messed me up, and that only lately with a particular project that is kind of crowded in a somewhat limited-size interior Thanks for the thought.

    Parameters > Camera? I must be misunderstanding something here. I don't see any options about cameras in the Parameters tab.

    (A few moments later)

    Ah, you mean click onto the camera I am using IN Parameters and adjust the focal length in Parameters. Aha!

    I am so stupid. I have actually done this many times before; just not in the last few months and so dopey me apparently forgot how to do that!!!  (facepalms and then slaps self upside the head)

    Thank you very much. I *knew* I was able to somewhat adjust this setting somehow before; I just simply forgot *how* I did so. like a dope. So again thank you very much for the help. It's not *precisely* what I was looking for as I wanted to be able to change the aspect ratio without the other directions *also* changing on me to make it look like the camera has altered its distance further back (still do if anyone knows how that can be done), but it serves very well for my purposes in the meantime.

    Aspekt Ratio has nothing to do with zooming. That is the ratio width to height, and you can set it in render setting > general.

    I have always known how to change the aspect ratio. What I don't know is how to change it without my apparent camera position changing at the same time.  I don't know any other way to describe what it is I seek but to refer to the aspect ratio, which seems to me to be an unavoidable aspect (pununinteneded) of the problem. 

    You know how the screen shows what part is inside the render area and which part is not? Say I have a scene with a 16:9 aspect ratio. There are parts above and/or below this area I want to include in my render without changing any of what is or isnot included from side to side and without changing my camera's distance from the subjects. I can't do that. Changing the aspect ratio by oitself does not help with this; because it changes what i see from side to side. Do you know how I can make it stop doing that?

    If I understand you correctly, this is something I face as well.  There is, no doubt, a mathematical formula for accomplishing this with precision, but it would take me too long to suss it out.  Here's what I do.

    1. Change the aspect ratio until the frame is tall enough.
    2. Slide the focal length until the horizontal field of view is back to where I want it.

    Neither step changes either the camera postition or its aim.  I may have to repeat both steps a few times because I just guide everything by eye, as in, "Whoops, too tall.  Start over and make it a little shorter."  Hope this helps.

    The control you need is Frame Width in the Camera parameters. Adjust it by the same factor as you adjust the height of the aspect ratio (e.g. if you double the height, you also need to double the frame width).

    Thank you.  Yes, that's a more precise method.  I still might need a couple of tries to get my vertical height right, but the math with keep the horizontal field of view consistent.
