Keep shutter speed below 200 to stay in sync range. For my purpose 200iso, 200shutter, F5.6 works great in Manual mode.<BR/>2. Set Flash to manual power 1/32.<BR/>3. Position flash about 2-3ft from wall at 45degrees up.<BR/>3. Placed my lee filter strip onto the flash and used the flip-down diffuser to hold it in place and remove that hot spot in one go.<BR/><BR/><BR/>My general advice on filters is to pick the darkest shade of colour available to get the best colour out. I define darkest by the fact that when you lay such filters on a piece of white paper they actually look black. <BR/><BR/>Thank youAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2312640351553996069.post-29499690818257809242009-03-11T21:18:00.000+00:002009-03-11T21:18:00.000+00:00Hi Christian,Off the top of my head I would try:1....Hi Christian,<BR/><BR/>Off the top of my head I would try:<BR/><BR/>1. Adjusting the angle of incidence for your coloured light source to try and increase diffuse reflection.<BR/>2. Underexpose for this light source to saturate the colour.<BR/><BR/>Let me know how you get on.<BR/><BR/>Yours,<BR/><BR/>DavidAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2312640351553996069.post-53536884433998315312009-03-11T20:46:00.000+00:002009-03-11T20:46:00.000+00:00David, I'm trying to use coloured gels to shade th...David, <BR/><BR/>I'm trying to use coloured gels to shade the colour of a background wall for portraits. Whatever I do I still seem to end up with a mainly white wall with only a hint of colour. How do I get a nice rich colour cast. <BR/><BR/>Any help appreciated.<BR/>Thank youAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2312640351553996069.post-30729462671701328512009-03-10T16:09:00.000+00:002009-03-10T16:09:00.000+00:00Hi Dominic,An interesting idea.

If it helps you understand the problems that cameras have to face in determining exposure then that's great.<BR/><BR/>I imagine you're setting Live View to exposure simulation and then either putting the camera in Av mode, and using exposure compensation, or manual mode.<BR/><BR/>Yours,<BR/><BR/>DavidAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2312640351553996069.post-6168683117883493292009-03-10T15:26:00.000+00:002009-03-10T15:26:00.000+00:00David, I've been using liveview on my 5D2 to help...David, <BR/><BR/>I've been using liveview on my 5D2 to help me understand the relationship between ISO/Shutter/Aperture in realtime without taking pics. You can see the effect of your changes as you dial them so a great learning aid tip for others maybe.<BR/><BR/>Downside is if you have a Speedlite active, it's useless as the histogram underexposes hugely in preperation for the flash - still it's nice to see how the camera is 'thinking' about exposure with Flash. You're also stuck with evaluative metering in liveview.<BR/><BR/>Bottom line, if taking pics with ambient light you can use Liveview to nail your exposure in realtime.Anonymousnoreply@blogger.com
