Exposure overlay.

As it's cold and the light flat outside thought I'd have a play with the E5's exposure overlay feature.This seem to be akin to Photomatixs exposure fusion.

1, Straight Raw developed in Silkypix.


2, 5 frame braket exposure fusion in Photomatix from Jpegs converted in Silkypix.


3,In camera exposure overlay using 4 Raw frames,four seems to be the maximum you can use in camera.


I think the colours in the photomatix image look off but that can be corrected.
I sky has blown in the exposure overlay image out of the E5 but the colours look good, maybe I should have started with exposure compensation lower,if I get time I'll try later.
Not very scientific but just to give you an idea what can be done.

Re: Exposure overlay.

There is more highlight detail in the first two (especially in the paving) but the overall tone of the last one is more attractive - crisp comes to mind

Re: Exposure overlay.

Were you using auto levels to combine them? I wouldn't have thought to overlay bracketed images in the multi-exposure function (being available on the E30 as well). Interesting idea & results.

Well not quite sure what that is.On the E5 once you have four Raw frames(does not seem to work on Jpegs)you display the first and then push the OK button and select image overlay.It then shows the other files and you can select those that you want.The O/P image is a Jpeg.
There probably a lot more things that you can do that I have not found yet.

Next crappy day

Re: Exposure overlay.

Great idea Andy. I hadn't got round to looking at these goodies but up to now they were not important - until now that is

Re: Exposure overlay.

Interesting but initially disappointing.
I had the same feelings when first using the Sony alpha-450 and its 'HDR' 3-exposure fusion thingummy. It just overexposed everything and the skies were totally blown.
It turns out you have to expose for the brightest area of the image, recompose then shoot the frames : then it works fine, keeping sky details and bringing up dark areas very well.

Perhaps in the e-5 there are variations according to how exposed that first frame is.
Try exposing for the sky and see what it gives you...

Re: Exposure overlay.

I don't think it was ever meant to be an answer to HDR, just for creative overlays, like adding a moon the scene or a lovely naked lady (taken against black) overlaid onto a dark forest scene or someone dressed like a ghost & adding in to an old building which could be the same setting (with camera fixed on tripod) with the model in one & not the other, giving the ghostly appearance. That's my evil thoughts for now.

I'l just go out now & do some work in my workshop on a wet dreary day here.
