Subject: camera focus

i have been trying some large renders, 3000 4000 pixels wide. but i have noticed that the main figure is out of focus. its not noticable untill i enlarge the image. but i am thinking of getting this image printed and would like it sharp, so is there a tape or some other way of finding out how far away the camers is from the figure and or what is the best way of setting the camera up. as always thanks ahead of time

Try to zoom in on the figure to get the camera a bit closer.

very funny
Thank you for your post but that is of no help,
I am looking for something a little more technical.

what are your render settings (screen capture of the settings dialog if you can)?

which version of poser are you using?

what file type are you saving to?

are you using the dept of field effect?

I'm not sure if I understand your question exactly.

If you select the main camera, the x_tran and z_tran numbers should show you how far away it is from your figure (assuming it is in the middle of the scene... if it's not, then you'd have to pull out good old Pythagoras to find the distance between the two). I wasn't aware of camera distance making images out of focus though, unless it's veeeery far away.

Or is your problem that you have the preview window at 3000x4000 and so you can't really see how the camera is aligned? In this case, you can resize your preview window to fit your screen and then just click the little arrow underneath the camera movement buttons. Somewhere in that menu, you can specify the render output size and set that at 3000x4000 (keeping the preview window at 750x1000 for example).

the only way it could be out of focus is if depth of field is used.

to find the distance there is a python script around here somewhere... i think it is called dofdistance or something like that.

if your not using depth of field then the blurry image is caused by something else... probably the render settings; Min shading rate, and post filter size.

it could also be caused by image compression if saving as a jpg.

Could it be the texture maps for the figure that aren't quite up to the job? I haven't tried such large renders myself, but I assume if you render a portrait in 3000x4000 and the texture map for the characters face is 1500x2000 for example, that that might make it appear blurry or out of focus?

click on one of the camera controls, and, depending on version, there may be a "focus_Distance" dial.

If you have Poser 6 or 7, there's a FocusDistanceControl prop. You can line it up with the character, and it should be perfectly in focus.

svdl, when you say prop do you mean a prop in the porp folder?
thank you miss nancy i have found the camers controlandi am test ing it out to see how it changes the image. also thanks to all that replyed. i will let you know how i got on

To increase your range of focus.; try moving the camera away, with the Camera's Transform Parameters(Probably zTrans;) and then increase the camera's Focal Parameter

I believe SVDL is talking about the the Guide at Display > Guide > Focus Distance Guide.

As stated above, unless you are using Poser 7's Depth of Field option, you shouldn't have a focus issue. By default, EVERYTHING should be in focus, regardless of the distance from the camera.

I suggest posting the problem image. Perhaps what you consider 'focus' is something entirely different.

If we can hit that bullseye, the rest of the dominos will fall like a house of cards...checkmate!
