Hey guys. If taking shots and you know your going to be taking pseudo HDR images would it be better to shoot them 1 or 2 stops higher exposure to avoid noise when adjusting exposure in photoshop? Or do you need that range of -2 -1 0 1+ 2+

If you are taking a single shot and you know you are going to make a single image HDR out of it yeah a stop or so brighter might be better as there is more info stored in brighter pixels.. little hard to explain but its called shooting to the right (you can read this if you are interested).

But yeah the important thing is the expose it so you capture the detail in the dark and bright areas - and in some cases this will simply not be possible with a single exposure - and then.. you'll have to do a proper HDR!

Why would you take 1 pic for a hdr image? If your intentionally wanting an HDR image and you're already there with your camera... why not take the extra shots?

I guess the only place you'd do it is if you took a pic, and thought it might look good as as afterthought, but if that's the case you're probably not going to get what you're after or had in mind anyway... Seems like a redundant thing to do.

It's hard to make an HDR pic not look flat and boring and lifeless as it is. Sounds like a Pseudo waste of time.

Might be a scene with heaps of moving objects and stuff

I don't think so Matt. Due to the nature of a HDR you will loose dark shadows and bright highlights. So to make photo not look flat you have to fix this afterwards. This is not hard to do if you have something like Lightroom. Its simply a matter of opening the tone curve and darkening the shadows - (drag left hand side down a little) and making the highlights a little brighter (drag light hand side a little up)

hdr in motion! good call

I don't mean they're flat as in just how they're coloured and lit, i meant more in general, I'd prefer a good normal pic to a good hdr 9/10. Occasionally they're awesome and do a great job, but usually it just seems to take away from what ever was the reason you stopped to take a pic. personal preference i guess. :)

IMO a good HDR is one you can't really tell it is a HDR!

      I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.

      Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
