HD photos ?

samhail

i saw a post here at one stage about someone posting their first HD photo. it was nice.

I tried to look online to see how it was done but no luck.

Is it a special camera that would have been used ? or is it just a nice photoshop job to enhance the colors ?

HDR? Its post processing of one kind or another. Well some cameras will do it in camera but you are more likely to do it in post processing.

http://qtpfsgui.sourceforge.net

This is free software which does it for you. The idea is you present the software with a series of exposures of the same scene - for example taken at -2, 0 and +2 and map the tones based on defined algorithms.

I haven't yet got anything that i'm happy with, but you probably need the right kind of scene to do as a HDR - my guess is you can't just take any old image.

You can use more than 3 exposures too AFAIK.

interesting, will have a look at that app. i wonder if it will accept the RAW file

From my efforts to date - you present it with a series of JPG's at the various exposures.

If trying it, it does take a bit of figuring out so allow time.

There are most likely other options out there.

you mean HDR not HD and yes, it is a process done on computer, any camera can capture the original images

IMHO the best HDR shots are the ones where it's not apparent that it has been done.

I have this image in the up coming Kilmainham Gaol Exhibition.



I think I used 4 RAW exposures in that. The result is close to what you would perceive you see when you are in that Chapel, though the difference in the highlights & shadows was well beyond the range of a RAW file.

There was a HDR thread recently on the Digital Darkroom forum..

And here is an excellent tutorial from Madeleine Weber (calaido) which is what got me started on HDR.....

I used PhotoMatix to do the HDR

Amen to this This was the original intention of HDR processing, that in one image you could display a dynamic range that was far in excess of what could ordinarily be captured in one shot.

Either Fenster or Fajitas has some shot of the inside of a church which I used to drag out on a regular basis to demonstrate what a proper HDR was meant to look like. IIRC Both the inside of the church and the stained glass windows were seperately exposed for and then combined into the HDR image.

Of course at this stage HDR is practically a term of abuse, and rightfully so given the abominations it's normally associated with...

Bing!

Lately on this forum, I've been seeing a lot of skipping steps. I don't mind skipping steps if you're able for it but a lot of people seem to be missing the basics in photography.. Ah well, no skin off my nose.

is the picture I was referring to above, Fenster it was. Although CabanSails shot serves equally as well as an example of how to go about assembling a good HDR. Interestingly enough, in that picture above Fenster references an earlier shot he'd taken of the same church which I think actually demonstrates some of the things NOT to do in a HDR composition ...
