So one of my friends pointed me in the direction of an HDR thread on nasioc the other day, and being that I thought the pics were pretty cool, I figured I'd try some shots on my own. Here are the results of a few experiments. I know that they're grainy 'cause I forgot about using a low ISO, there are halos in some high-contrast areas, the lens is dirty, etc. etc., but I felt like sharing. If you feel like critiquing other aspects of the photo, feel free too, but just keep in mind that I'm not a professional photographer... or anything near it That, and this was my first time doing this, I have a crappy tripod, I had a 2 hour time frame from taking the pics to processing them (including driving back and forth), etc. etc. I have my excuses lined up, haha

Halos




Cool concept but the execution sucked




Also, I'm sure it's been done before, but if anyone feels like sharing their HDR shots, feel free to. I'd like to see what you guys have, too.

 

looks cool, but whats HDR?

Im thinking something like High Definition Resolution, or something to that extent.

 

love your avatar frank

 

your the second person to say that tonight, and its only been up for about 2 hours.

whats new? hows the car?

 

It's High Dynamic Range.

What aperture did you use? Generally in a HDR you see sharp detail all the way through the image. i.e. No use of shallow DOF to blur or soften the background. It's personal taste and taste is subjective of course.

They are all good for first try. Composition-wise I like #3 the most as it is closer to abiding by the rule of thirds than the others.

 

thanks.

so how is it accomplished?

 

By merging multiple exposures into one and then tone-mapping it.

Some people use 3 exposures, some use up to 7 or even 12. I most often use 5 myself.

-2 EV
-1 EV
0 EV
+1 EV
+ 2 EV

Generally use a tripod. Set camera to Manual or Aperture Priority and alter the shutter speed by 1 stop each shot or simply use your camera's exposure bracketing mode and continuous high speed shutter. The later method (combined with alignment function in most HDR software) will allow you to take quite reasonable hand-held HDRs if you're in good light.

You generally don't shoot people or moving objects this way for obvious reasons but if you really wanted to shoot a person (sitting for example) you might try using as low as 3 frames.

The original poster has done well in that he has no excessive haloing around objects. Haloing is often considered poor HDR by afficianados of the style. You will often see this around buildings, trees and other objects.

 

It's taking multiple shots of the same subject at different exposures and combining it into one single image.

There's a few of these in the Photography forum

Here's one:

Thanks! I actually took these with shutter speed priority (except for the last pic), which I realized I shouldn't have done later on, but because of this, f-stops generally varied between 5.6 and 8. Next time I'll shoot with aperture priority and a lower ISO to see what sort of difference it makes.
Like I said, the last shot was an exception, which I shot with an f-stop of 3.6 for all 3 exposures in an attempt to create a shallow DOF. Yeah, that's not what HDR's are for, but I wanted to try it I also realized I only varied EV by +/- 1, so I have to fix that for next time Also want to try shooting in RAW to see if it makes an impact on quality of the final image.
BTW, yeah, I usually shoot with rule of thirds in mind, but I wanted to experiment with different positioning of the car
