Hi,

I have to admit to taking a liking to some of the HDR pics that have been posted on here, in particular some of the work by Garrie. Anyway with that in mind and in between working very hard at the office today ;) I have done a bit of digging around to see what`s out there. All of these have a free trial period with a watermark left on the image or some other limitation but certainly OK for folks to play about with. Might be interesting to see what people come up with.

Yep I understand this is not everyones cup of tea, but I guess we could say that about other types of photography.

Some links

Photomatix. $99 US
http://www.hdrsoft.com/download.html

Artizen HDR $45.95 Canadian ( about 23 GBP according to my currency converter)
http://www.supportingcomputers.net/Applications/Products.htm

FDR Tools 49 Euros
http://www.fdrtools.com/fdrtools_advanced_e.php

Easy HDR 30 Euros
http://www.easyhdr.com/

There seems to be various plug ins about as well, though nothing for GIMP users just yet, unless I missed this! Think I might play around with some of this at the weekend.

Hope this helps.

Good set of link there :)

I bought Photomatix and just 100% use that as its simple to use (needs to be simple for me) and canny powerful at what I use it for.

Have fun playing.. I've still got to process a set of pics from a site I visited last Sunday.

Cheers

Hey nice one there John with those links. I took a shine to EasyHDR after seeing some of their examples on the site.

I have Photomatix, but might try this as it's only a few Euros. Thanks for the link.

I have just seen some results of HDR and I am well impressed, so I am going to try a couple of programs and choose the one I can use the easiest, never ever thought that a picture could come out like that, well just goes to show how wrong I was.

Many thanks Scapula Memory for the links.

I've never managed to get this working in Photoshop. Each time I try it tells me there's not enough dynamic range between the source images despite amending them to +/-2 EV.

Do show us your results when you have done some, always love to see HDR stuff :)

Plug-in for GIMP - I've used it, gives a fairly subdued result compared with other programs, but as it presents the image with layers and masks can be tuned.

(sometimes the link fails - I suspect due to the edu server)

Thanks Nick, useful link I might give the GIMP another go now I have a bit more memory in the old notebook.

FYI: theGIMP is also now available for Mac's as well as PC's. I used this only for a short while when I was on a PC and found it an excellent application. How they have managed to keep this free I'll never know, it's one of the best free apps out there (together with irFanView that is - wish they made that for OSx)

just tried Artizen HDR - makes me cold, way to difficult to use for me (I am kinda thick :o), not as easy as photomatix, although i've used photomaitx a lot longer.

Freebie HDR - GNU

Qtpfsgui (that really is its name)

from

http://qtpfsgui.sourceforge.net/

Dark image is original (hdr by creating +-2ev from single raw)

Only just given it a quick try, interested to hear comments from anyone else who has a play

Thanks for that link Nick. I wouldn't mind trying this out but which version did you download. I don't understand what Bleeding Edge and Stable versions are?

Bleeding Edge has, or may have, bugs.

Stable, means the developer doesn't think it has bugs merely character and features.

I downloaded both, Stable does not seem to have the Help section installed, whilst Bleeding Edge does. I used Bleeding Edge.

Must admit I found it a bit challenging to get my head around the tone mapping - but then I don't understand tone mapping - yet. One of the reasons I hope others play with it.

Nick,

Thanks for posting this useful link. I have played about a bit with the bleeding edge version and like you I could not make it out at first. The help section is there but I found it to be empty.

What I found useful was the filename automatically mirrors the settings, so that might be useful to make a copy and remember how you got there. This looks to be a very good little program although with a few quirks.

Anyway here is my first attempt, this took about 10 minutes time wise. Any thoughts , ideas?

If Garrie the TM master sees this your advice would be appreciated!

Can anyone recommend any good on-line sources on tone mapping and how the various methods work. Qtpfsgui has tabs with labels like Fattal, Durand, Reinhard, Drago (wasn't he in Harry Potter?), each with various bits to twiddle.

I like trial and error - but a bit of theory might help.

I suppose it pays to look first and ask second.

So here are a couple of pages I'm finding useful

http://luxal.dachary.org/webhdr/tonemapping.shtml

which describes (at an overview level) Fattal et al and the ideas behind them.

and

http://www.mediachance.com/hdri/help/index.html?tone_mapping.htm

which while based on their product provides one of the best overviews on HDR and tone mapping I have seen (product looks quite inexpensive too - for those of you who feel you must spend money).

Hey Nick - sorry, I missed this request.

Here's an article that I particularly found useful. The tog is a chap by the name of Pete Carr, who is particularly prevalent on another forum.

Hey Bud,

Sorry missed your last comment, had a little too much wine this evening, lol.

I'm not a Tonemapping master, just like to mess around with the settings. Know a little theory about TM and will help where I can mate.

I'll try my best to help, although I only use Photomatix. Can you email me the files so I can have a play? email addy is garrie@daydesigns.co.uk

I'll explain every thing I've done to create the final image.

Cheers

Thanks Garrie,

My intention here was just to show the effect of what qtp was doing in a certain mode. Neither images are that good in my opinion. If possible then I can email to you the first helicoptor pic for you to play about with, and which is better for you a raw file or the jpeg?

Some basic explanations would be great. I do not have Photomatix but can probably make some sort of cross reference to qtp. Much appreciated.

I understand about the wine, I am the same on the 3rd bottle.....:D

Hi there,

Try this link as it gives some technical advice and background that may help.

http://www.cambridgeincolour.com/tutorials/high-dynamic-range.htm

It goes through HDR and tonal mapping.

Aaah just re read that and it sounds like I was on the 3rd bottle that time of the morning LOL : Absolutely NO WAY! it was the second bottle....:D

Will get the file off to you tonight Garrie, but no rush and much appreciated.

Just a note to like minded people who use Photomatix Pro. This has so far been poor at processing HDR images from .ORF files without introducing pattern artifacts into smooth gradients and detailess areas like skies. Similar to what ACR RAW conversion did to .ORFs before 4.3.1 came out.

There is a latest Beta version of Photomatix Pro 3.0 out that has now banished these pattern artifacts (I used to call it 'mosaicing', maybe wrongly) from ORFs and has a slightly better interface when tone mapping. You can download it here

http://www.hdrsoft.com:80/download/beta/win30.html

for Windows and here

http://www.hdrsoft.com:80/download/beta/mac30.html

Tried and paid for version 3 ( a beta ) this weekend. I particularly like the way you get to see the changes as you do them. To get a 15% discount type in DOPphotomatix in the coupon bit or VPG15 or if you type in photomatix discount from a Google search various options are available. Saves about 8 quid. The weak $ at the moment means it is a good time to buy.
