Click For Summary
Discussion Overview
The discussion revolves around the topic of photomanipulation and digital arts, specifically focusing on photography techniques such as HDR (High Dynamic Range) and depth of field enhancement. Participants share their experiences, tools, and methods for manipulating photos to achieve better results.
Discussion Character
- Exploratory
- Technical explanation
- Conceptual clarification
Main Points Raised
- One participant expresses interest in starting a thread for those who enjoy photography and photo manipulation.
- Another participant shares their initial experience with photo manipulation, mentioning the use of HDR techniques and the software GIMP, along with a desire to assist others with the installation process.
- A participant describes the process of taking three photos at different exposures to create an HDR image, highlighting the challenges of overexposure and underexposure in photography.
- One participant shares their results after merging images, indicating satisfaction with the outcome.
- Another participant introduces the concept of depth of field enhancement, particularly in macro photography, and discusses the need for static subjects when taking multiple pictures for this technique.
- Links to additional resources and programs for depth of field enhancement are provided by one participant.
Areas of Agreement / Disagreement
Participants generally express interest and share techniques related to photo manipulation, but there is no explicit consensus on specific methods or tools. The discussion remains exploratory with various techniques being discussed without resolution of preferences.
Contextual Notes
Participants mention specific software and techniques but do not delve into the limitations or assumptions behind their methods. There is no discussion of potential challenges or prerequisites for the techniques mentioned.

Okay why not.
Until today I did not do any photo manipulation. Just used the tools in the standard programs, like Canons DPP and Picasa and such.
But I felt the need for using HDR techniques, so I started contemplating to buy a software package for that. However google is your friend and I downloaded a public domain program, gimp following a step by step instruction that I found in Dutch, which included the manual installation of a plug in. If anybody is interested I can translate that and assist.
Next you need three pix, from the scenery, identical albeit one over exposed and one underexposed. Many cameras have programs for that (AEB), including the canons.
So I put the camera on the tripod, took a corner in the living, including the window which gave way too much contrast and the AEB took three piX:
first the normal exposed pic. The problem should be clear, the window is strongly over exposed while the shadows lost most details.
The next shot is under exposed by two stops, resulting in only a correct exposure for the window
and the final one is over exposed two stops, resulting in correctly exposed shadows only
We load the three pix in the program, sprinkle some stardust and wave the magic wand, voila; the three pictures merged with all parts exposed correctly:

Thanks, Georgina, I'll play with it some more later.

Tried it today on a bit more interesting scenery
Again, the normal exposed pic:
after merging with an under and over exposed frame (not shown) we get this:

Another trick I stumbled upon is depth of field enhancing. Especially when shooting macro the very shallow depth of field can be embarrashing like this:
Body crisp, wings blurry.
The Depth of Field enhancing works with multiple pictures too, focussed in different planes also merged together. Obviously taking multiple pix requires an absolute static situation, so you'd have to work with static objects too e.g. dead insects. Not my style.
Anyway I found some info and programs for that, maybe I give it a try:

Those are stunning photos, pictures merged with all parts exposed correctly. Good stuff!
