Next week - Critique over everything...

As discussed in class, Tuesday will be a work day to assemble your Stack Attack images. I would like you to have 2 completed by critique on Thursday. So, basically you need to have 2 shot by Tuesday. Please ask yourself, "What is this about, what I am saying?" for each of your composite images. It is not enough to simple implement the technique. The complexity of what I am asking you to do is increasing both in terms of technical mastery as well as conceptual rigor.

On Thursday, we will have a critique looking at everything that you have done in class thus far. Here is a list of what I expect that you should have ready to show:
1. 1 HDR image
2. 1 Night Shot
3. 1 Panorama
4. 3 Holga shots
5. 5 shots taken outside of the above assignments which are on the same theme addressing some aspect of the urban landscape.
6. 1 Impossible Shot - aka the Stack Attack image-you will need to complete 3 total, but only 1 has to be completed for critique

I don't think is this asking much at all. Of course, each of these should be really solid images that you feel really good about. They should be edited to the highest degree that you are capable of. Please assess your images critically before asking the class to do so. I want you to turn in a CD/DVD with all these images as full resolution, flattened TIFFs.
Feel free to email me with any questions or work in progress for feedback.
Happy shooting!

Content via Stacked Imagery - aka the Stack Attack- aka Impossible shots- aka Single Space Composites

Your assignment is to create four strong images that make use of stacked imagery to illustrate a particular view or concept. Noah had the really good idea of shooting a closed Ford dealership in which only foreign cars drive by.
I was thinking a shot of a gas station with only gas guzzlers like Suburbans, Hummers, Yukons, etc populate the pumps and parking lot.
I also suggested using this technique to illustrate/construct traffic patterns. You could show the number of people who go into the liquor store versus the neighboring Christian bookstore over a 2 hour period.
You are to have at least one image shot for this for this evening. You will work on assembling the composite images in class.
I am really excited about this project and expect great, thoughtful work.

Technical overview:
Shoot everything using a tripod.
Use a remote release if possible.
All setting on the camera must remain the same between shots which means focus, exposure, ISO, and white balance must remain the same for all the shots.
It will be easier to combine the shots by making masks if everything in critically sharp, so I recommend using a larger depth of field. This isn't necessary, but it will facilitate the creation of the composite.
If you can get a shot of the scene with no moving subjects, then be sure to get it. If you do so, you won't have try to create an "empty" scene using the various smart stack blending modes. Basically, t will save you a lot of time.
You will use layer masks to only include those elements which you wish to include in the final composite.
It might be easier to mask the subjects out using the layer mask and then invert it rather as we did in class. This will result in a layer with only the desired subjects visible.

Excellent little article about the capabilities of image stacking. This is the Gizmodo posting that I showed you in class.

PDF write up by Martin Evening (one of the best) on how to use layer stacks to remove unwanted moving subjects from a scene using layer stacks.
