My name is Carol and I head up a Photo Club in Indianapolis, Indiana...USA. We have 194 members (on the books)...but probably about 50-60 who are fairly active. Our club (all volunteers) offers educational classes/meetings for beginners, middle of the road, and possibly for more advanced later. We do photo shoots/outings/events/exhibits and contests. A lot of interacting and hands on with our learning. We chose "Cambridge In Colour" to be our point of reference several months ago and just did get started with a 6-month educational program. We changed some of our website contests...one being "Photo Challenge".
Each month, there will be a new challenge. For the month of March, the person who came up with the challenge is calling it "Multi-exposure composition – 2 images blended into one". I thought he was talking about HDR...but he says,
"I really was NOT aiming for HDR with the multi-shot composition. Yes, for some combining images could be done in camera (with less control) and others would likely composite certain elements from one pic into another in post. In my opinion HDR is a very specialized type of processing and usually composite of multiple exposures of the same scene. You can fake HDR on just a single image. I would not trade HDR for a 2-image composition for the category. I can see someone putting a person shot at one location into another environment. Or dropping in a moon on a scene where the moon wasn't available, or simply creating something surreal with a texture added to a sky, or how about a disproportionate element- a man standing on a Coke can. I'm sure if you time the composite/muti-exposure category with an education session it would aid those who may be less clear on what direction to take. Does this help flesh it out more? I didn't throw out my ideas with an exact, strict definition. The expectation was that you would take what you wanted and shape the idea into a category that made sense.
I'm still befuddled on what he wants us to do and was looking at your site for one reference where I could direct our members re this. I'm quite the amateur myself and not able to answer this; I want our folks to rely on your site when in doubt and to enhance their learning experiences. Can you help me out on this one??? My "category" person is not available...
