Antwort von molch:

you could not theoretically halbbildverfahren exploit for hdr?
one knows of it-3d shutter glasses: the transparent lcd glasses darken in the high frequency s.and again.
would do this with the 50i a camera synchronize einhalbbild would normally, and an increasingly be underexposed. these fields must nurnoch seperatiert and combined.


Antwort von Debonnaire:


May I ask you, links to external websites / documents that always installed as external links, so that as a window is not lost?

Thank you!


Antwort von grovel:

May I ask you, not to do so? I will even be able to decide when a new window is opened and when not.

At least in Firefox I can every link, if I want, in a new tab / window open by saying either the link with the middle mouse button or normal with the left and at the same time, press Ctrl.

There is somewhere a software or a workflow (script), with which we not only images but synonymous movies (mpeg or avi) for HDR processing?
Would be useful for example in the digitization of short films on a video camera. The problem: Narrow films usually have a contrast ratio of approximately 1:3000, good cameras but can not exceed in a Picture a contrast ratio of 1:1000 process.
This means that either the lights "burn out" and the black "absaufen".
Were the film digitizer 2 times - once hochbelichtet low and once exposed - could the problem be solved. If it were a software which synonymous films (including interlacing) could handle.

Manual I have the problem ever with CS2 right.
I am as follows:
1.Hochbelichteten and low-exposed film with AFTER FX psd-image processing. (WARNING: only the psd format does not destroy the Halbbildreihenfolge. All other format such as FLM, bmp, tif, etc. lose the interlacing info)
Then, in Photoshop following tasks: a picture of success HDR images from one highly exposed and an associated low output illuminated image (psd format, 8 bit) via batch processing for automatic processing without interruption can be generated.
The hochbelichteten source images are located in the "HIGH" with the syntax "high0001.psd" to "high9999.psd" and the low-exposed source images in the folder "LOW" with the syntax "low0001.psd" to "low9999. psd ". The destination folder is "Target", the edited images to the syntax "end0001.psd" to "end9999.psd have.
All output images have the same format and the same size. (8 bits, psd, RGB)
The actions should be:
1. Open the first low-image "from the" LOW "
2. Opening the first "high-image" from the "HIGH"
3. In Photoshop FILE> AUTOMATE> "At the HDR merge. Options: Align images: on / use: open files / ok
4. In an öffnenten window EV manual setting "is the" high-Picture "of the EV-value 3 is assigned, and the" low-Picture "of the EV-value 0 Ok. Window: To join with HDR ok to confirm.
5. In 8-bit Picture convert with method: histogram equalisieren (Menu Picture> Mode> Convert to 8 bit)
6.Bildgröße Bicubic propotional not convert to 720x576 pixels. (Picture menu> Image Size)
7.Speichern the first Endbildes in the "TARGET".
Images 8.Alle close.

Thereafter, the whole thing for the 2nd Picture etc. etc. until the last Picture automated.

Despite long-experimentation is neither succeeded me, a working (passing) or a batch processing function to create droplet.

Manual work is very good, very expensive if synonymous.

The target image is again a PREMIERE avi together. The result is SUPER.

Unfortunately my knowledge in order to automate a script to write. Can someone help? Or is there already a solution?

It would be nice if someone could help.

Gruß Thomas
