What is HDR ?

[William]

Mr Felix, Here's an example of HDR from one RAW file that I did of mine , It has movement in it , The Waves !!

[Mr Felix]

Thanks William,

But is the one I submitted qualify as HDR?

Just the smoke seems too "clear" to be a normal picture.

[William]

Yep , I'd say by the look of it , It's a single RAW image HDR , Mr Felix , Go to photomatix web site you can download a free trial version , Just has water marks on the images , Or buy for $90 , You just have to load one RAW image in , Use the default settings for processing and you'll get what they call a pseudo HDR from a Single file , Which works if there is a heap of movement , Thats the easiest way

[Mr Felix]

Thanks.



I shall also have to find time and sit down with fotoshop and learn how to do all those/these tricks.

"HDR stands for Hard to Do Right "

don't you mean Hard to Do Tastefully?

I actually blend my HDR images by hand, now that I have a graphics tablet (wacom intuos4) I can do it significantly faster and with far more control than what was previously possible.

[Mr Felix]

OK, next question.

My 330D made .CRW files.

Now with the 550D and I take RAW images, I get .CR2 files.

Adobe says it can't load them.

Short of re-naming them - a typical windozxe fixall - what do I need to do to get Adobe to load the files?

[William]

Into what editing program ?

[Mr Felix]

PhotoShop cs3

[William]

You'l probably need to update to CS5 for it to read .CR2 files from a 550D , Each new version of PS includes updates of new Cameras , Dont think the 550D was out when CS3 was released

[Mr Felix]

Ok, next question.

For the sake of learning, while at Parramatta this morning, though I don't do raw files because of the problem mentioned above, I bracketed a shot of some balloons. PhotoShop didn't mind loading the three pictures with the HDR thingy/function.

Ok, it did some things itself but then what happens?

I tryied to save the picture but couldn't save as JPG.

Saved it as the PhotoShop format and tried to look at it.

It is HUGE! And it won't load. 23MEG I think.

I am trying to get my head around the process, but if someone wouldn't mind giving me a bit of help.

HDR are 32 bit images. JPG are 8 Bit. If you want to save the resultant photo, go to Image > Mode > and change it to 8 bits/channel and then you can save it as JPG

[Mr Felix]

As you can see, I am not good with the programs features.

This thread has clarified a few things about HDR. Thanks to all.
