BW Versions of Yesterday's HDR

Just to take yesterday’s images the next step, I converted the two tire pictures to B&W to see how they fared.

I converted them using CS3’s Black & White  Adjustment tool. To keep the comparison fair, I used the same conversion settings (established for the HDR image and copied on the straight image):

  • Red   27
  • Yellow 30
  • Green 55
  • Cyan 53
  • Blue 188
  • Magenta 60

I adjusted Blue the most to get the detail in the tire the way I wanted it. Yellow darkened the background a bit.

Then I adjusted them both in Levels for Black/White Points and Midrange  (2 – 1.07 – 249). Again, I kept them the same to provide a clearer comparison.

This is the B&W version of the non-HDR image:

And here they are smaller, but side-by-side:


The back grounds are different, but that could be adjusted if I focused on refining each one to to it’s own range.

The straight image pops more because of the stronger blacks – the HDR shows a fuller range of values, dropping the pop factor for the greater range of detail. The full Black and Whites are there, I dialed them in using the Levels adjustment. But since there is less over all it flattens just a bit. But I enjoy looking at the HDR image more – there’s more to look at. Like looking at an Ansel Adams, the more you look the more there is to see.

Now I need to explore pulling an HDR from a single raw, for those moments when you can’t bracket – or when there is a variable element in the image – like a person who refuses to sit completely still. We’ll see where that goes.

One thought on “BW Versions of Yesterday's HDR

  1. This is an interesting set of posts (on HDR). I’m interested to hear what you decide. I also tried Photomatix a bit to see if I liked the results. I’ll save my opinion until you finish the series. I agree with your points about keeping the objective in mind. I’m also very interested in whether you think pseudo-hdr from a single raw file works. I’ll tune in then. Peace.
