Along with that, orbiting an object would b`e useful if that's not already there. Wow that's a cool image.

For minute camera movements, try holding the middle mouse button down while moving the mouse.  Using the scroll wheel will also give smaller forward and backward movements.

this makes no difference on my computer.....is this the short cut for minute camera movements ?

With the scroll wheel you can move with small increments forward and backward.

Normally you can use [SHIFT] to accurately move sliders but with the zoom slider it does not work because it moves with integer values.

TIP: You can also double-click on the Focal length slider and type in a value manually, e.g. 15.1 degrees.

Just bear in mind that it will switch to your saved camera views when you use the numeric keys (I've already reported this on the bug tracker list), but at least it lets you change the zoom factor with greater accuracy.

but i find that zooming CLOSE UP ,using the  focal length adjustment.....
creates camera shake, as you can see in the tv teaser. at the end. the keyboard trembles as it slow zooms

Could you try to add a "Camera Clip Planes" effect to the tv teaser clip and increase the "Near plane" slider value as much as is possible before it begins to clip objects in the scene, then render it again to see if this reduces the camera shake?

I have been on vacation for the past week; however, I have just confirmed that you CAN pan (up, down, left, right) the camera in very small increments by depressing the scroll wheel and moving the mouse.  I am using Build 7.

Edit:  I am also able to use the scroll wheel to make smaller front/back adjustments than by using the arrows.

Dazomatic you are absolutely right. Thanks for the video Zoom to prove.
The arrows and the mouse are not accurate at all, when we talk centimeters.
Remko and Morten, please add this request to the wish list.
That would seem to them if, since the button Shift increases in speed the movements, which that of Ctrl diminishes glaringly.

This has been one of my primary frustrations with this program.

I have spent hours using the arrow keys to get a particular camera angle.

There needs to be a key you can use to slow down the camera.

As I noted previously, it is perfectly possible to move the camera a very small distance with great precision.  To accomplish, hold down the scroll wheel on your mouse and move the mouse a small distance.  It is very easy and you don't have to press any extra buttons.

Hi Dazomatic, can you upload the scene files please? I can't seem to get the camera to shake, even if I use the maximum focal length (300mm). The scene consists of two files in Documents/LumionFree/Scenes.

Correct, also make sure that Settings -> Speedup camera movement is off if you're trying to move the camera around.

@Morten,

I have speed up camera movement activated and do not have any problems with small movements.

Besides all the other advantages a scroll wheel offers (viewing web pages, zooming in Photoshop, etc.) it seems that it would be worth it to spend $30 - $50 on a mouse that ends your frustration.

I have a Logitech M704 that is bluetooth.  The receiver is very small, so I just leave it in the USB port, and the Logitech software allows you to configure the buttons for different programs.  You can also pair multiple bluetooth devices to the same receiver.  Fifty dollars over the life of the product is less expensive than the headache pills I would have to take while using my favorite program (Lumion :-D).

Plus Logitech mice ship with a 3 year warranty, so you can't really go wrong :)

Update:

The shaking camera is caused by socalled floating point accuracy:
In real-time 3D graphics, the position of an object is specified by 8 digits for each axis, e.g.:
X = 180.90123
Y = 43.143467
Z = 1427.7927

The laptop in your scene was placed at xyz (350.xxxxx, 10.xxxxxx, 350.xxxxx).

The further away objects are from 0,0,0, the more jittery they and the camera become since there are fewer digits after the comma to ensure accuracy. This may not sound like much, but if you placed the laptop, say 4000m from the world origin, the camera shake would be even worse. Obviously you couldn't possibly know this since Lumion currently doesn't display the position of objects.

In the upcoming SP2 Build 8, however, Ferry has made it possible to see what the position of the currently selected object is, provided that Settings -> "Show Frames per Second" is switched on. If you move the laptop to a position close to 0,0,0, the camera (and the laptop) won't shake anymore.

This should make it possible to render close-ups /product visualisations without problems in the future.
