HDR with RAW

Hi all, This seems like it should be obvious or at least easily findable but perhaps my Googling is shoddy! I have a K1ii and I was trying the HDR function shooting RAW. I shot a shot (the top one in the attached) with no HDR and the bottom one with HDR and it shot three images and took a while to blend them. It looks a lot more HDR on the back of the camera. I take it into Exposure X5 and it just looks identical. All the HDRness is lost. It looks right in XNView (screenshot added).

Do I have to use Silkypix to do the edits while retaining the HDR look?

Thanks!

Phil

Re: HDR with RAW

It is likely your raw converter cannot handle HDR raw files. it is just selecting one of the three captures to present to you during editing. That is I guess why you do not see a difference.

Re: HDR with RAW

Doesn't the in-camera HDR function only output a JPG ?

Re: HDR with RAW

I can see the results on the back of the camera and in Xnview and I read a lot about people using raw to do it though I can't imagine how it works.

Thanks. Do you know what editors can handle them?

Re: HDR with RAW

I use LR as the first stop, and don't recall having problems importing an in camera HDR dng file. The latest version of ACR also handles Pixel Shift as well, but I believe DCU5 is still better.

Re: HDR with RAW

Interesting. I don't use LR. I just installed DGU and it's good to have that as a backup though it's so slow and clunky that would be a rare thing indeed.

Thanks for the help though!

I think Silkypix Developer Studio Pro can.

What I do however is to take 3 or five raw shots using bracketing and then process them in Lightroom using the HDR merge tool.

The K1 and K1II have such great dynamic range it is often just as good to make a raw capture exposing for the highlight regions and then bring out the shadows in PP. This avoids the need for HDR.

Re: HDR with RAW

Yeah, I use Photomatix to bulk process RE images. Realtors all want HDR! I just wondered if I could do it in camera but it seems impractical.

Re: HDR with RAW

I only use DCU5 on a limited basis (pixel shift), and you're right it can be a little clunky to use, but for what it does, it does it well.

You can produce a JPEG in camera in HDR.

Re: HDR with RAW

Of course! I was narrowly focused on RAW. Thanks for the reminder. I'll see how that does.

Yes, this is what I do, with a single image. I use the HDR tool in Silkypix, it works well for the majority of cases except of course the most extreme dynamic range.

Single photo not really HDR

Usually HDR means higher than what camera can do with a single photo. Why call something HDR, if it is normal performance? Decent dynamic range has been there for several years and little improvement since then. HDR is not the same as lightening shadows strongly with post-processing which either produce noisy mess or the scene has low contrast which is not really HDR either.

The main reason for HDR and HDRish post-processing confusion is that many displays have low dynamic range or are very small to make the difference between HDR and fake HDR:

I am not sure you are right. I only think HDR means mapping a high dynamic range image to a smaller dynamic range, matching the output medium. If the original comes from 1, 2, 3 or more shots does not really matter.

But sure, if the camera has an HDR mode it usually means taking three images.

Re: HDR with RAW

Everyone does HDR a little differntly - a diffent mappping of a high DR image to a jpg 8 bit. By HDR effect, i tink we usually mean that local adjustments are made to brighter and darker areas of the image, a bit like dodging and burning.

That said, if you like the Pentax flavour of HDR, make sure you save a jpg in camera. I've noticed that these are pretty good in some cases, and the K1ii will auto align the 3 images, giving much sharper results that some raw developers *coughlightroom*.

Here's one, in camera HDR was better than what i managed in LR. Maybe my LR skills need tweaking?

Re: HDR with RAW

Actually the K1MII has several options for composing HDR in camera,  Auto, 1,2,3, and ADV. Auto chooses the bracketing, 1,2,3 is predetermined, and ADV is similar to HDR 2 with a boost in contrast and saturation. If you shoot raw you have the option of selecting one image and discarding the others. I rarely use it,  prefering batcketed shots composited post, so i cant really say how well it works.

Re: HDR with RAW

Now that's a great idea! Shoot HDR in camera and convert in camera to JPG then you have the option to use the JPG or the RAW in  Pentax software afterwards.

Who wants 'HDRness'?

I am not sure why anyone would want the 'HDR look' - that usually means that something has been overdone. If the camera is already capturing the full dynamic range of a scene in one shot, surely a natural-looking 'HDR' shot shouldn't look any different.

This has probably been pointed out already, but Lightroom is one of the easiest possible ways of achieving HDR. Just fire off three bracketed shots, and LR blends them in moments, including alignment - and will save them as a DNG image. Much more control than doing it in the camera.

I use LR to do a HDR merge from bracketed shots. I think it works well.

As far as HDR "look", if it is overdone and looks unnatural then I don't like it. HDR merge either in camera or in software is very useful in a high DR scene like an interior shot but with a window showing a bright scene outside.

What we see with our eyes and what a single camera exposure can capture are two very different things. Our eyes compensate automatically and very quickly, the camera cannot in a single frame. So when you use terms like "natural looking", you have to allow for the fact that a single capture may not be "natural".
