If this is part of a page layout, you can have a separate stylesheet for edit mode that relaxes your fixed width or removes your branding altogether to make it easier to modify web part properties. You would use an EditModePanel. 

I've done things like this in page layouts:

&lt;asp:Content ContentPlaceHolderID="PlaceHolderAdditionalPageHead" runat="server"&gt;
&lt;PublishingWebControls:EditModePanel runat="server" id="ContentDisplay" PageDisplayMode="Display"&gt;
&lt;link rel="stylesheet" href="mydisplaymode.css" /&gt;
&lt;/PublishingWebControls:EditModePanel&gt;
&lt;PublishingWebControls:EditModePanel runat="server" id="ContentDisplay" PageDisplayMode="Edit"&gt;
&lt;link rel="stylesheet" href="myeditmode.css" /&gt;
&lt;/PublishingWebControls:EditModePanel&gt;

How does the colour of ambient lighting affect colour rendition?

For example:

If I stand under a sodium-vapour (orange) streetlight and calibrate my camera's white balance, what effect would this have if I were to take a photo of a colour test chart?  Presumably, white would still render as white due to the white balance calibration, but how would other colours be rendered?

How would the result differ under primary and secondary coloured lighting, e.g. a red or yellow light?

Thanks.
