Hello good people, do any of ypu have any good advice, links, videos for creating hdr on Lightroom from single raw file? I know its normally a bracketing process, but im trying to work on a few pics from football matches where bracketing won't really work. Thanks in advance
 
Could you create two virtual copies, turn exposure down on one and up on the other - then do a HDR merge? (although you might end up with a replica of what you had?)
 
You will be limited to the dynamic range of your camera. You cannot extract more information if it is not there. Why are you getting such high dynamic range scenes at football; we see plenty of football shots without this problem. If the DR of you camera is very poor then the only solution is better camera.

Photomatix does a fair job of HDR from a single raw, once you get the settings worked out it can produce fairly natural looking images, without the OTT look.
 
Why? What for? To create putrid look - look at photomatox indeed? Or to recover some shadows or highlight which can do depending on cameras ability and settings used. If thats not enough maybe time for a better and newer kit

I can think of a few reasons, such as for presentation on an HDR display.

Modern cameras can capture more bit depth than can be printed or displayed on an SDR monitor; with HDR you gain extra impact from illuminated light sources (screens, signage, lights, etc) being restored to their proper tonal values beyond 24-bit. HDR is becoming commonplace in cinema and home entertainment motion video setups, why not also stills photography?

Highlight and shadow recovery is a palliative fix for the limitations of common display technologies. I’m old enough to remember when we had to knock photos down to 8-bit colour for applications on computer screens.

Above all, HDR ≠ tone mapping. Indeed the need for tone mapping is a consequence of historically not having adequate dynamic range in displays.

These are valid points, but precisely none of that requires creation of HDR file particularly out of single RAW
 
I've hesitated about contributing to this thread but........

What is the difference between a file underexposed by two stops in camera and one underexposed by two stops in software? Is there a difference? I think that's what the OP wanted to know.
 
You can't really because the dynamic range can't be better than the one image.
But a properly processed HDR image is not immediately different to a normal image, it is only the overcooked ones that look immediately different, so may be it is the "HDR look" that is wanted? In which case, you can develop it to give about that look
 
Thanks to those of you who have given me a helpful answer to my initial question, its very much appreciated. Unfortunately (as seems to be the case with all too many threads here) there always seems to be a few people who feel the need to put others down with snide and unnecessary commitments.... not helpful at all folks. Im sure you've heard the phrase before... "if you cant say something nice, then just be quiet". For clarity, and for the helpful people who tried to reason the question, it is with the aim of producing slightly artistic and surreal images, and not just football pics.
That's my rant over. Thanks again to the nicer people here who are very helpful to someone trying to improve.

Yes, there are one or two....... but its not too bad here generally.

It's always the same ones as well I've noticed, but in the main peeps here are very helpful and friendly
 
Yes indeed, I have got some wonderful help for the good folks on here
