HDR Photography
Hey gang, I happened to see some HDR photos and was really impressed. I'm starting to get the bug to try it myself and was wondering what I'd need to get started. I have a canon eos 10d; Photoshop Elements 6 for Mac, and a newer Imac running Leopard. I've read about a program called photomatix; but would I be able to do HDR photos with Photoshop Elements 6? I have to assume not as it was only $89..

Do I have any of the necessary tools or would this be a big expense to get started? Thanks in advance for any advice..

Steve..

Get a tripod and also google a software pkg called 'bracketeer'..

HDR=High Dynamic Range photographyto do hdr-.

If you put camera into full auto matrix metering, take first shot note fstop and shutter speed. put camera into full manual, see if camera still has the matrix fstop and shutter speed. if yes, then using shutter speed go up 2-4 shutter speeds 1 fstop worth of shutter speed at a time. the back to matrix shutter speed and go down same number of shutter speeds..

Christian bloch in his hdri handbook did a test of 1 fstop bracketing vs 2fstop bracketing. there was an obvious image quality falloff using the 2fstop bracketing. if the image quality decline in 2stop bracketing is acceptable to you then use the 2 stop. 1 stop is recommended for max image quality, though of course it needed more shots.this is on a tripod with cable release..

No, you should not use 1 raw shot and convert 1 stop up and down, because their is not enough dynamic range in the 1 raw shot. dynamic range is why we are doing this, hdr is trying to get all it can. If you use a single raw shot and triple convert it, you still end up with no more DR than the single raw shot..

The group of shots can be raw or jpeg. if jpeg they can be used as is. if raw remember that you HAVE to batch process all 3-9(?) shots. this is because the pp has to be all the same on every pic. you cannot, for example make any attempt to get the shadow details of the group of raw pics, because that would require different amounts of pp, and you cannot do that with hdr. the pp for all shots has to be identical..

For me I just shoot them in jpeg and use them from the camera, that way they are all identical because the camera jpeg settings are the same for every shot. I also put my hand streched in front of the lens and take a check shot and when done take a ending shot with hand. this tells me where the hdr group is on my memory card when I transfer to the pc..

The only important item is to bracket using shutter speeds only. if fstops are used it changes dof between shots. and shoot enough shots, 3-9(?) is the optimum. the only other thought is to shoot a scene that deserves the the hdr technique, too many people are shooting hdr because it is new or different or whatever. many people are using hdr software on scenes that do not have enough dynamic range; they end up with images that have been enhanced by hdr software, they are not hdr images. the dynamic range was not in the scene to begin with.

This can be checked with a spotmeter on different areas. NOTE: use of auto bracketing on a camera may not work unless you know the bracketing is using the shutter speeds to bracket. in any event, you really need 3-9(?) shots for hdr; this is more than the auto bracket fcn on almost all cameras. and the bracketing has to be both sides of the middle shot. make you use enough brackets to cover the previously checked dynamic range.

And the scene should have no movement, if so the item will blur in the hdr image..

Do not adjust the focus. set the focus on infinity or use a hyperfocal setup for focus..

Do not adjust the white balance for individual shots. go with awb or 1 setting and do not change it..

Remember, hdr was created and meant for scene that have a dynamic range that exceeds the dynamic range of the camera sensor, about 5-6stops for jpeg or 7-9 for raw. hdr with the required software allows the user to capture a scene that has very high dynamic range..

I currently use Dynamic-Photo HDR and recommend it. Less than the price of photomatrix and it has 6 different looks, (the photomatrix look is included), and each of the 6 looks can be fine tuned. Get Dynamic-Photo hdr here-http://www.mediachance.com/hdri/index.html also included is a program that is part of DP hdr that can make a fake hdr look image from a jpeg..

Pp. after the hdri is made and is in a folder, I open in pe6. there I use noise ninja(to reduce noise), auto levels(to give a normal overall brightness amount), and focus magic(to sharpen and give a better focus. also if focus magic is used do not sharpen at all, that is double sharpening and is guaranteed to make artifacts.). save as tiff. DO NOT USE AUTO CONTRAST OR ANY OTHER CONTRAST ADJUSTMENT.

Also do not adjust any shadows or bright areas. the point of hdr is to let the shooting of multiple shots and the hdr software combining of those shots take care of the dark areas and bright areas. if any areas are dark or highlight blown, then the brackets were not extended out far enough from center...

There is a fundamental difference between hdr and exposure blending. it is not just a look, it is intent of the technique. assuming that you have 3 shots of a scene, and the scene is worthy of hdr at all(not all are), and the shots are plus and minus 2ev from the center metered shot and you have the center shot also. what exposure blending does is that the process selects the properly exposed portions of the scene from all 3 images and literally puts them together into a image in which all parts are properly exposed. but in the real scene that you saw with your eyes there is also a relationship between adjoining sections of the scene. if part a and part b adjoin each other and a is twice or four times as bright as b, then with your eyes that is what you see looking at the real scene with your eyes.

The 2 parts will appear exposed right but the 2 times or 4 times differnce in brightness will not be right or even present..

If the above 3 shots are processed in hdr software. the actual 32bit image, which cannot be seen in true form, only parts of it, maintains the relationship between any and all adjoining parts of the image that have any brightness differences. then through the process of tonemapping the 32bit image is changed to a 8 or 16bit jpeg or tiff. this image is maintaining the image differences and brightness differences between the adjoining sections and NOT just using the properly exposed sections..

The gradient between the sections is being maintained in hdr in an approximation of the true real scene. in exposure blending the only criteria is that the parts of the scene are all properly exposed. hdr is trying to show what the scene looked like in it's real form and view while exposure blending is just showing an image that has no wrongly exposed parts..

The software that can do exposure blending is Infuse and Enfuse. Either works both are similar. Some other exposurte blending programs exist, or it can sometimes be found in other software. For example, PTGuiPro(panorama software) has the ability to make panoramas normally or with HDR or exposure blending...

Hi Everybody, thanks for the reply.. Gary, thanks a lot, thats what I needed. I have to mess with all this once I digest it. I'll check out that software, thanks for the link..

Edit: It appears that software won't work with me imac. Oh well..Thanks again..

Do not know what software works with macs, but there has to be some for hdr. you can also see about the phony pc setup that you can put on macs to allow the running of pc software. virtual pc? maybe..

The rest of the info should apply though...

Try this link, this is impressive HDR software. Really powerful. You can download a test patch. Did the one below the link on the Hard Rock at Universal OrlandoJerry.

I use Dynamic Photo HDR for my HDR shots. It is about 50% the price of Photomatrix and I think both are excellent programs but I wanted to save the $$. Here is an example of one that I used DP-HDR to produce. It's an easy program to use and works much better then trying to do HDR in Photoshop CS3. I've never used elements..

Wow, that came out really good..thanks for the advice..

Hi Maddog and Orlando, thanks for the recommendation, but I don't think that Dynamic Photo is built to run on my Mac, unfortunately I'm not running windows on my mac.. Thanks for the recommendation, though..

There is a book by Ferrell McCollough called HIGH DYNAMIC RANGE where he explains all of the present HDR programs..

I know that Photomatix Pro and Dynamic Photo hdr both have trials that you can download.These two are standalones that do not depend on what editor you are using.Try the it's a lot of fun...

Comment #10

Photomatx Pro will run on Mac,google it and down load the trial..

Comment #11

I've been playing with both Photomatix and DynamicPhoto fairly intensively for the past few days. I went up to Kings Canyon NP to get some shots that would benefit from HDR (and to get out of the heat ). This is a good time of year because you have mixtures of dark shades in the canopy as well as sunlight and clouds (afternoon thunder storms)..

What I think I've decided on is that DynamicPhoto is a little more difficult to use at first, but much more flexible in it's application. Now I find it easier to do what I want w/ Dynamicphoto. One thing I especially appreciate is the ability to batch process images. For example, the images below were captured with EV ranges between 5 and 9. I saved several different versions of each in the batch processor (along with many other images) and ran them on my computer all at once. I havent done any post processing other than the HDR, so I think these can be improved some still..

DynamicPhoto also allows pin warping and manual alighnment. Pin warping lets to save those images where your tripod moves (i.e. rotation). Dynamic photo also has many other modes that you can use. I also think it is much easier than photoshop (CS3) for processing HDR images..

I use photomatrix for combining 3 exposure brackets and the plug-in "Redynamix" for HDR type work.

Thanks for the head's up. I checked out the plugin and found that they also had a plug in for CS3. I downloaded the trial and it works really well. So I'm back to evaluating again . Labor of love I suppose..

Thanks,.

Hey gang, thanks for the replies; those were some awseome pictures...

It depends on whether you want artifically hightened image or just are looking for really good depth and image quality. I find this method works very well (particularly to convert to B&W). Unless I'm doing something wrong, it's farily simple:1. You have to use a tripod2. Use the 2 sec shutter delay to minimize movement3. turn IS off4.

Shoot RAW if at all possible.

5. take a bunch of shots without changing focus or aperture, doubling up the speed from the darkest to the lighest image.

6. if you have PS3 it's simple: in Bridge Tools>Photoshop>merge to HDR and let the computer do the work for you..

7. finally, save the resultant image as a 16-bit TIFF file, edit in PS and when done, convert 8-bit to save and print..

I'm not saying the image below is an exemplar of the best use of HDR, but is a quick shot taken in my kitchen using this method and took a total of ten minutes to take it, play with it and produce the "finished"HDR image. Hope this helps,FHPhotographer.
