Narada Falls, Mt. Rainier National Park, Washington


This is a High Dynamic Range Image, necessitated by the sun on the top of the falls, and the darkness in the canyon below. The HDR exposures covered nearly 4 stops range.

Technical Details: Canon 5D, 24-70mm f/2.8L lens, B+W circular polarizer. Exposures were f/22 for 1/13 sec, f/22 for 1/6 sec, f/22 for 0.3 sec, f/22 for 0.6 sec.
Post processing included color balancing the shaded area (warming it), enhancing saturation, adjusting levels, and contrast.

This is a nice shot but the difference in shutter speed for the sunlit exposure vs shaded exposure makes the water look different. It kind of jumps out at me in the smaller picture. I think the grad ND filter would have been a better choice here.
I've been enjoying your other photos - keep up the good work! Greg

Thanks for your comment. I appreciate your comment about using a grad ND rather than using HDR...I'm a BIG fan of grad NDs and generally take the approach that capturing the exposure correctly in the camera is far better than relying on post-processing.

With this image, I'm not sure that the grad ND would have done the trick - because of the spotty sun exposing just a part of the top of the falls (admittedly, I didn't try the grad ND on this shot).

I find grad NDs to work best when there is a moderately clear "horizon line" (even if the split in illumination intensity is not exactly at the horizon...when the illumination intensity is split between top and bottom (or side-to-side), it is relatively straight-forward to use one or two grad NDs...when the illumination is mottled or spotty...it's a harder judgement call.

Let me know your web-links and I'd be interested in learning from you images!

Best...Richard

Hi Richard,

I agree with the difficulty on using the split ND in this situation. It would be interesting to see a composite based on lightest and darkest exposures from a single RAW capture.

I have a site at www.ggimages.com

I think most of the learning is on my end though :) I do find it so educational and inspirational to look at other peoples pictures to see techniques that I just haven't thought of.

Best Regards,
Greg

Hi Richard,

I just noticed you're in Woodinville, I'm in Snohomish, just up the road. I actually found your site looking for photos of Robin Lake (yours is really nice by the way) as I'm headed up there this weekend.
