HDR/HDRi and Tone Mapping - - One file HDR

saby · #1 11-21-2007, 08:56 AM

the hdr of this tonemapped picture created by the FDRT(http://www.fdrtools.com/front_e.php) shareware and the tonemapped by the qtpfsqui freeware, what is the most universal tonemapper what i've ever used.

what do you think about creating hdr from single file and how do you like this picture?

Hello Saby...

I really like your HDR....I do many from just one photo and am usually pleased with the results....In Dynamic Photo there is the way to do with just one pic...there is a thread here and i posted some of mine done with one!

I shoot in RAW now and you get a good result from doing 3 or more pics with the exposure levels changed...when doing just one JPEG it can be very noisy so then you have to use a filter to take it away and then it will take some of the effect away too....The Qs program you mentioned i have just downloaded so will try to get to grips with it ....I have also been experimenting by taking the pic from one program to another...I really love the hdr effect wether it be subtle to enhance or extreme...depends on the photo!!!

Hi Patricia,

thanx for Your kind words,

It was the first to do hdr from one jpg, U've right, at tonemapping (qtpfsqui fatal function) there was lots of noise, some afterwork needed, but what I really can't get: how could just one jpg contains that mutch detalis than raw or does it interpolated? I'll read this thread above...cheers

To answer your questions Saby I like your image very much, Is it some sort of mill ?
and as for using one image if it works, it works ! ! ! !

I have used Qtpfsqui before, but since we changed pc I haven't re loaded it, even though it is only the trial i prefer hdri ( what Patracia uses )

Saby here is one i done using Qtpfsqui (#9)
http://www.retouchpro.com/forums/pho...rocky-mtn.html

It is ok to use but i didnt quite understand it all so just used to mess around with the buttons to see what would happen. I probably didn't give it a fair chance though

But it does come at a excellent price

Hi palms,

It's very nice, I think U did it by the fatal function what is the most interesting tonemapper in qtpfsgui, the others for to displaying the hdr and the rest, I'd never used because I couldn't get good looking result. I think this software could get better career by another name

Very nice image and I liked the way it turned out. I think you get a much different look with tonemapping just the one image, doesn't look hdr, but still like it. It almost looks like LucisArt to some degree to me.

Hi Dennis,

I recognised some snapping in gradation, could I avoid that if I'd more than one shot or save it as raw? I'm realy new to hdr and photography as well, so I need some suggestions about: how to?

Nice one Palms....the colors are poppin and thats what we want......I love this tone mapping and if ever you have a pic that is underexposed if you put it into Dynamic Photo(must get hubby to treat you to the full version) it really saves the image and looks pretty good!!!

DWTomp....Lucis art is a brilliant plugin and you can do so much with it....its exciting though that there are many free HDR programs to play with too....

Saby....Always shoot in Raw for whatever photos you take....I was so nervous about it but when i started just a few weeks ago i chose the option where it took JPEG and RAW....When processing the RAW files do 3 or more...one normal exposure,1 +2 and 1 -2....you can do more variations if you wish...You will find the quality of your finished HDR a lot better and hardly any noise..My favorite filter in Photoshop for processing any kind of photo is Highlight and shadows...it does amazing things to your pics...just got into using the adjustment layers too....So much to learn and very far to go...but this is how i spend all my free time.....Try it and let me know how you get on!!!

Possibly. I only shoot RAW and I love the flexibility it provides. There are some excellent HDR tutorials around, but here are some basics. IMO there are 3 ways to process to HDR.

1) tonemap a single image. While this is not true HDR it does offer some nice looking results.

2) process a RAW file into 3 different exposures. The true dynamic range is still limited to the original shot.

3) take 3-5 shots (1-2 stops apart) with only the shutter speed different to capture the dynamic range of the scene. Auto exposure bracketing works well, especially if you have clouds or water movement. Also, while not necessary, a tripod is recommended. I bring the RAW files directly into Photomatix without any processing in ACR.

Just my opinion, but not every scene needs HDR. Some scenes you can cover the dynamic range in a single shot and they don't benefit. You can get some very interesting effects tho with tonemapping.

I agree Lucis is a very, very cool plugin, but I wouldn't classify it as HDR (it's probably not what you meant, just wanted to clarify). A little Lucis can go a long way.

Yep, its a very handy filter. The fill light and recovery in ACR can also work some magic at times. Layers and adjustment layers are your friend

Dennis you are right i wasnt classifying Lucis Art as HDR...just a great plugin with some amazing effects if not too overdone!!!

What is ACR??? Pardon my ignorance but dont know all the abrieviated terms!

You have explained HDR really well ...thats what i meant but didnt quite come out as well as yours!!!

Do U know about HDRShop(http://gl.ict.usc.edu/HDRShop/), I've read the tutorial about the camera response curve, -U can check @ the link- I understand what it for, but could the resulting hdr better if I define it?

Patricia, I was pretty sure you weren't, just wanted to clarify. Lucis is amazing, but for the life of me I've never figured out a use for the "plaid" settings.

ACR is Adobe Camera Raw. I use this for my RAW conversions. I think it started with CS2 Photoshop. The latest is v4.3. I started using it for my conversions in CS2, replacing Canon's DPP. Adobe really added some nice tools with the CS3's ACR. In fact, I'm finding that I'm doing more corrections and tweaking in ACR and less in Photoshop.

Nothing wrong at all with your explanation of HDR.
