A few of my images, C&C please

[patham]

The first two were taken with my old PowerShot A590IS, so I'm looking more for input on composition technique rather than camera settings on these as the input is quite limited... (click images for bigger size)

Ideally, since flash was not allowed, I should have set up the tripod, taken another picture at a slower shutter speed to grab the details on the cross and surrounding walls and then do an HDR merge. But due to time constraints that was not possible and my hands aren't steady enough for hand holding the camera for that long... So I'm really interested in tips on making similar shots better.

Hi Patrick,


Interesting shots! Here are some specific comments:


#1) The horizon isn't level, needs a few degrees of clockwise rotation. Might have been nice if you could have pulled back just a little so the reflection of the top of the building wasn't cut off.


#2) I'd compose/crop tight enough for just wood and insect, so the subject is the only green in the image and you get a better view of the interesting texture of the wood as well. Also, I think a vertical composition would be better for the shot.


#3) Scenes like this are a challenge! First off, if you were not shooting RAW you should be especially for a shot like this, since RAW allows you to recover the image much, much better than JPG. The first thing I notice is about the image as shot - you're at ISO 3200 which is fairly noisy on the 500D, but you're also at 1/640 s shutter speed and a focal length of 48mm. Even with a reasonable safety margin (say, 1/160 s shutter speed which is double the 1/focal length approximation for handholding), you could have achieved an equivalent exposure with much lower noise at ISO 800.


While HDR would have been an excellent choice, it's not always possible to set up a tripod in a church, either. The highlights are well-protected - perhaps a little too well, since the white areas of the glass clip in blue or green, but usually not both and not all three. Generally, clipping in the white part of a stained glass window is tolerable, although you want to preserve the highlight detail in the faces. So, with only a single shot to take, I'd have pushed the exposure a bit to the right (2/3 - 1 stop) to open up the shadows, then done some highlight recovery in post processing. One related option would have been to take several exposures (+0.5 EC, +1 EC, +1.5 EC), not for HDR (although I've done that successfully with the 8 fps on a 7D) but to select the exposure that allows you to recover the shadows best while preserving the highlights. Some programs (e.g. DxO) allow a pseudo-HDR from a single RAW image, or you can process your single RAW image with different exposures (and noise reduction settings) in your favorite RAW converter, then fuse those in something like Photomatix. If you'd care to make the RAW image available (e.g. with yousendit.com, which allows you to share large files for free), I'd be happy to have a go...


Hope that helps...

Hi John,


First of all thanks for your very helpful comments!


#1) Unfortunately going further back wasn

[TucsonTRD]

I agree with John on most of his points and I will add one for pic #3. I think if the cross were lowered slightly so the circle with the adult and child were unobstructed, and had the cross just below them, would improve this photo. That may not have been possible though. As you would have to move back and/or get higher.

John, regarding #3, the original RAW file is available here: patrickdurham.net/.../339.CR2

Ok, Patrick, here's my attempt at recovery from the RAW file:

Wow...that

Any chance you could explain the workflow on this so I can learn?

Certainly. Would have done so earlier, but I ran out of time between meetings. It was not much of a workflow, to be honest. I used DxO Optics Pro, and first I downloaded the necessary module (500D + Sigma 24-70 f/2.8), added +0.67 EV exposure adjustment, set the DxO Lighting (HDR) parameter to Auto - High, and processed the image.

Now I also understand better your previous comment on the ISO...while the grainyness wasn't as readily visible on the stained glass, the cross in front of it looks very grainy...

Yep. Noise is always more evident in the shadows (where there is less signal), and bumping up the EV to open up the shadows increases the visibility of the noise. I find ISO 3200 on my 7D to be a bit too noisy for my taste (and it's a little better there than the T1i/500D I started with). ISO 1600 is tolerable, but I prefer to keep the ISO at 800 or less when possible. ISO 3200 on my 5DII is much better, but I still stay under 1600. Also, I've found that DxO does a better job at noise reduction than DPP.

Would it be possible to do the same single image pseudo HDR with Lightroom?
