HDR ? Stacking ?

[Deleted member 23476]

Hey,
I have a small problem at the moment for my exam i have chosen to focus on stacking. Anyway i have decided to try and get myself more marks to look deeper into stacking and look at a technique. Now i know about focus stacking but would you also count HDR as stacking.

The reason i count it as stacking is you have to import and stack the images in a program before merging them into one.

Anyway want to know your views on this, thanks in advanced.

Not technically called stacking, but the images obviously have to be overlayed on each other to achieve the end result - you do get the option in Photomatix (or is it easyHDR?) to manually align each imported image - I'd say stacked then merged would pretty much describe HDR....

Have you considered the stacking astro photographers use to put several images together to gain as much light as possible from faint deep sky objects, which also has the benefit of reducing the signal to noise ratio. This form of stacking will register the objects within the shot, even though they may have moved during what could be a large number of exposures.

Or a slightly different form of stacking that allows several images of the night sky to be stacked with the frame itself registered, so that the movement of the stars during several exposures are shown as light trails.

Ye, exactly how i thought as well so im 99% sure i should be fine now. Tutor just said i need to prove that HDR is a form of stacking.

Very intresting ideas there thanks for that, if anyone else has anymore ideas for stacking weather its a object or a technique please do share as i would be interested to hear it.

I was going to suggest the Astro stacking that Derek mentioned... You don't need a lot of expensive gear, but can achieve the results with a tripod mounted camera.

The other choice that springs to mind is focus stacking. Because of the extremely narrow depth of field in macro, you take a series of shots, moving through the object you're photographing, then combine all the images into a single image that contains all the in focus parts, giving you far greater DOF than would normally be possible. I'm afraid that my attempts at this so far have proved dismally unsuccesful though...

Ye i was going to try this as with spring now here and also my college having a nikon macro lens i am gonna give it a go.
