Some photography and HDR questions
Ever since the early part of summer, I kind of got myself into photography. I still have a lot to learn, but I'm hoping you guys can clarify some stuff and concept for me. I currently have a Panasonic FZ-8 and I don't intend to upgrade to a DSLR in the near future due to the amount of money required to get into that field..

For long exposure shots, do you guys bring a tripod? When I was in Beijing I tried to take some pictures in the dark, but the results weren't very satisfying even with image stabilization. I have a feeling a tripod is required, but to me it seems like a hassle to carry around. Are there any small portable tripod that I can easily stick into my bag?.

How does HDR photography work? I've seen some pictures with HDR effects and they're amazing. Are they true to colour or there are some artificial modication that makes it "better" than what it would appear in real life? From what I read, you would need three pictures with different exposure to make it work. Is this true? Is this where auto bracketing comes in? I probably have more than 800 pictures from my trip that used auto bracketing. I'm under the impression that with HDR photography, I can somehow merge all three pictures to get a better picture due to the amount of "information" that is available from all three pictures...

Yes, most image stabilization is only effective for 1-3 shutter speed equivelkants improvement, many are not even that effective.z>.

Yes, at the exposure you use for each exposure..

Sometimes, just like any other image..

So long as the bracketed images are identical in composition and at about 2 f/stops higher and lower exposure, they should work. Essentially, each of the 3 exposures records the tones in their respective range capabilities. Then, the lower half of the darkest, the middle of the middle exposure and the highlights of the lightest are combined to extend the detail in the tones that the middle exposure cannot differentiate..

As you have seen, it is quite effective, especially in certain scenes..

Do you have any recommendations for a highly portable tripod? Some of the tripods that I have seen are very big and are geared for professionals..

Yes, all of the pictures are an exact composition. All three shots pretty much go from dark to bright with the third image being the brightest..

What's an easy to use program to play with HDR photography? I know Photoshop has this feature, but I don't have PS and it's not newbie friendly...

If you didn't use a tripod for the three exposures, then they won't be exact exposures and will not work for HDR. You need two or more images that are exactly the same - meaning even if you do use a tripod, you can still have three exposures that are slightly different. If the wind is blowing the clouds will be moving or the leaves on a tree will be moving - these are different images, and won't work for HDR (or won't work nicely)..

One simple way to do HDR or HDR-like effects is to use blending in any photoeditor. Take a single image in RAW. Process using -1EV and +1EV, then blend the two images to create one. Here's a short tutorial on it:http://www.pixalo.com/articles/Photo-blending-using-paint-shop-pro.php.

These aren't tripods but they are small, portable, and can often help where a tripod is either cumbersome or even prohibited:.

The only problem I have with this is that you get no EXTRA dynamic range, All the data is available in the initial development of a single file. Under processing and over processing and recombining them is jsut extra steps to access the same data..

That is why you have to actually under and over expose, to extend the range beyone the sensors ability to record in a single capture. So, instead of having (say) an 11 EV dynamic range in one capture, you have 15 or so EV of detail to blend..

I said "HDR-like" effects. The end result is a properly exposed image across multiple exposures that your camera would otherwise never have been able to capture, except in some cases with a good graduated ND filter and proper technique..

Most photographers on here are DR-hyped up, thinking a sensor with more DR is somehow much better, and will produce much better images. If you think this is true, post an image with 9EV stops of DR and then complain how 10EV stops would have successfully made that image better. It's not going to happen..

HDR and blending is a step toward more DR and better exposure. HDR can make or break an image, as well as blending..

Tim, I agree..

I was not challenging your solution, only stating a preference for a different method. And, I like the ND approach, personally, if possible. It is also interesting to note that "spreading" tones in low dynamic range images can alter appearance and interest, just like HD..

My personal attention to DR is to in how and why it gets lost as a result of temperature, shielding (of lack therof) of componants and the effect that has on the final output of preceivable tone (and apparent sharpness) in the print (or on screen)..

I thinks we both did pretty good by the OP.Van..
