Windows Getting Blown Out
Posted: 7 Jul 2012 at 15:35 GMT
Is there a tutorial or video that shows how to shoot interior panos and making sure that the windows does not get blown out. Can anyone provide links or make suggestion on how to deal with that issue. Thank you.

There are multiple methods that would work. Bracketing 7 exposures (-6,-4,-2,0,2,4,6) might be a good start depending on the light difference. Sometimes I bracket more or less depending on the scene.

Use EnfuseGUI to combine all the exposures, stitch and then use masks in Photoshop to make final adjustments to the interior portion and windows separately. That's what I did with this 360 in late June.

This two part Architectural HDR Webinar might help too.

I use a 9-bracket set, with an EV of -2. SNS-HDR Pro is very good for processing these, since it has some cleverly-worked out presets and a rather useful highlights protection. Its downside is that the noise reduction and micro highlights functions are not that good. With highlights protection initiated, it actually adds noise with the former; the micro highlights also add noise in bland areas, such as blue skies, with the latter. As long as people know that, and are able to switch them off, then it might be one of the best hdr programs around.

I have also found DxO very good in processing raw images, since you can always protect the highlights with that (quite often stopping down an already down-stopped set).

For the initial exposure, I usually use a grey card, with the most even light source reflecting from that.

It pays to experiment, though...
