Nothing but white! No picture displays.

[sstoiche]

I have Backyard EOS 3.1.3 Premium edition.  My camera is a Canon 70D.  I have installed the drivers that came with my camera.  I am trying to take some test pictures indoors (camera is pointed to look outside the window).  I have the dial on my camera on M.  Settings in BYEOS is:  Tv=Bulb, Av=f/4.5, duration=5, ISO=1600, Pause=0, Frame type=Light, Cable support=Camera USB, Save To=PC, Mirror Lock=0, Quality=RAW+Jpeg.  I have the Imaging button selected.  Every time I click Start Capture, it takes its pictures and takes additional pictures if I have multiple exposures.  Every single time nothing but white displays!  I have selected the default camera driver (2nd button) on the opening screen.  What am I doing wrong?  I love the software, but am about ready to ditch it if I can't get this resolved.

 

Thanks,

Steve

Of course you will get an all white image with a 5 second shot during day time.

 

Bring that duration down to 1 second and if you have to go sub-second select a TV value (say 1-10) instead of bulb and you will get something back for sure.

Steve,

 

The problem is not BYE.  You can verify this by disconnecting the camera from the PC, aiming the camera out the window and then press and hold the shutter for 5 seconds.  The result should be the same.

 

The problem is that you are taking 5 second exposures (Shutter=Bulb, duration=5).  If you are shooting a daytime target out the window, your image would be completely saturated (all white). Try changing the Shutter (Tv) value from Bulb to a sub-second exposure like 1-1000 (0.001 seconds).

 

You should only use the BULB setting if your exposure length is longer than 30 seconds.  For shorter exposures choose the exposure from one of the other values in the Shutter dropdown list.  The advantage is that the camera will time the exposure which will give a more repeatable value than if the computer is timing the exposure and closing the shutter.

Looks like I figured it out.  The settings that I was using would be good for night images (I want to do astrophotography), but they were simply not right for day-time practicing.  I dropped the ISO to 400 and 800 and reduced the shutter speed and all is good.  I'm new at this and just learning.
