I have a 20D and 1DMk2, and I got the 1DMk2 for HDR, but it seems much better suited to BIF shots and wildlife.
I would really like to shoot up to 5 images for my HDR shots, and I can do that with the 1DMk2, but its a bit heavy and its pretty limited as far as wide angle.
I was thinking of a T2i, but I'm worried about the sizes of the images once merged. I only shoot RAW so with that camera using RAW I don't think I have an option as to RAW size.
I know the 5D3 would be great but I don't need or could afford it.
How about the 60D, what does that get me versus the T2i ?
Both of these of course would be using the Magic lantern software so I could bracket more images.
Any other options?

what about a 5D? you can probably pick one up for a good price too, considering their age.

sidenote: the 5d3 has built in HDR. here's a shot i took, hand held,3 shots, +/-3EV . it auto aligns the images too, in camera, and spits out this fourth image. http://www.epicdevelop​ements.com …s/2012/06/incam​eraHDR.jpg (external link)

the cons are it only creates the image in jpeg, and the styles of HDR are presets. the image above is the "art standard" preset.

Ditto the new T4i which also has in camera HDR for slightly less $.

On a tripod any camera will do the bracketing by scrolling the shutter speed dial.
If you want to do it handheld then having an extended bracketing function is handy. The 5DIII will do up to 7 in a sequence.

Smaller pixels on the sensor are more susceptible to noise in the image. Even at lower ISO settings.

Personally, I like the larger sensor because it means the wider lenses give me the wide angle and DoF I expect.

Hand held HDR brackets are already a quality compromise. I would be disinclined to add to the compromise with a small sensor that can induce noise.

My guess is that in camera HDR uses the same basic algorithm as the multi-exposure noise reduction function found in the T4i. That being the case, I suspect that this noise reduction technique is also applied thereby REDUCING noise in the final HDR jpg produced.

So the semi larger sensor which is on the 1D series is good as well as the 5D series ? i like the larger sensors, its just that theres not a lot of wide angle lenses to shoot with, comapred to the crop sensor bodies which have the 17-55, 15-85 and a few others at reasonablr prices as well.

The 1D has larger pixels than any of the prosumer crop cameras.
At 17mm lens on a 60D is about the same as a 24mm lens on a 5D in terms of angle of view.
There are lots of nice wide lenses for full frame cameras, 17-40, 16-35 zooms; 14, 24, 28, 35mm prime lenses.

I have a 17-35mm F2.8 L that is nice. Older lens but sharp. Its for sale since I have a 17mm TSE.

Regarding in camera HDR; That is a real compromise in my opinion. It relies entirely on the Canon algorithms. I always shoot raw and have never even tried it so don't really have any thoughts about the noise suppression. I expect that its there.

I'm wondering why this shot needed HDR. It looks like an overcast day; seems the scene should have been within the dynamic range of the 5DIII in a single exposure.

Now you've made me curious - I think I'll go get mine and try it to see how it works.

Quick and dirty In Camera HDR from T4i...no processing.

For HDR, it would be nice to have a camera that can do more than three bracketed exposures. Might only need three, some of the time. But other times, more may be desirable.

AFAIK, only the 5D Mark III can do additional bracketed exposures (up to 7 frames), as the camera comes from Canon.

There is a software available called Magic Lantern, that's loaded onto the camera and appears to give more bracketing (for focus stacking, too). AFAIK, it can be used on 5DII, 60D, T2i, T3i and perhaps a few other models. Functionality varies a bit, between the FF and 1.6X models.

ML also adds a lot of cinematography functionality. In fact, I think that was the original purpose.

It appears to have some limited usefulness with earlier models that didn't feature video, too.

Additional info about ML in this POTN thread.

and well it should for $3500 dollars vs. $850 for the T4i.

While it does up to 7 bracketed exposures in the auto bracketing mode, it only does three bracketed exposures in the HDR mode. They can be spaced up to 3EV.

I did some quick testing and came up with this:

IMAGE NOT FOUND
HTTP response: 404 | MIME changed to 'text/html' | Byte size: ZERO


straight from the camera as a JPG. (The three bracketed exposures are RAW since that is what my camera is set to record.)

This is the middle exposure with Lightroom adjustments.
IMAGE NOT FOUND
HTTP response: 404 | MIME changed to 'text/html' | Byte size: ZERO


This is the three raw files imported into CS6 via HDR pro and saved back to Lightroom as a 32 bit TIFF, then processed in Lightroom.

IMAGE NOT FOUND
HTTP response: 404 | MIME changed to 'text/html' | Byte size: ZERO


The in camera HDR, since it uses RAW files as captured by the camera could be a useful tool. The limit to 3 bracketed exposure is too bad.
