    Watercraft for On-Water Bird Photography

    I own a Native Watercraft Ultimate 12. It is very stable and I have used it both with my 100-400 handheld and my 500mm on a tripod. Photography on a kayak is challenging, but you can get some shots not otherwise easy to get.

    Green images

    In programs like Lightroom and ACR the white balance adjustment has sliders for both color temperature and tint. You can usually get this kind of color cast corrected with the tint slider. More complex adjustments can be made in the HSL/Color sections.

    Manual Extension Tube Question

    Just use your histogram. After a couple of test shots, you should be able to get the exposure nailed. I do this when shooting moon shots. The camera meter never seems to get this right.

    580 EX II

    I use mine for wildlife photography and I use it in ETTL mode most of the time. When the subject is farther away I use a Better Beamer with it. It really helps with back lit subjects and will get a catch light in the subject's eye.

    Macro Extenstion Tubes

    Your exposure metering should work fine as long as its TTL. Some extension tubes with some cameras will even autofocus.

    hyperfocal distances

    To answer your question, if the hyper focal distance is 1.5 feet, that means you should focus on a point 1.5 feet in front of the camera (in front of the focal plane actually). When you do that, everything will be in focus from infinity to half the focal distance, in this case 3/4 of a foot.

    Canon ETTL-II users only - Flash question

    Using ETTL, your camera should meter correctly even if a diffuser or flash card is used, and/or if the flash is set to bounce. This is because the flash fires an extremely short pre-flash and the camera uses that to meter the exposure. So no matter how the flash is set up, the camera sees the...

    Gray Card

    Well, if you shoot raw, you can put the card somewhere in a test shot and when you process your raw image, most software will let you pick on the grey card to set the WB. All other photos with the same lighting can use the same WB setting and you can usually apply this to a whole group of...

    Locking shutter speed whiile shooting in AV

    While the canon will not let you set a specific minimum shutter speed when in auto iso and av mode, the way auto iso is supposed to work is that it sets the iso to a value that does not let the shutter speed be lower than 1 over the focal length. So if your shooting a 100mm lens the shutter...

    Lightroom 3 book suggestions

    I have the Kelby LR2 and LR3 books. They are great books for learning the program. Kelby takes you through the modules, one by one and offers lots of tips and suggested settings. I would recommend it.

    North Carolina?

    Hey, LittleJohn. Do you know the Peedee Wildlife Refuge well? I was over there last spring. It would be good to go out with someone who is familiar with what is going on at the site.

    Photoshop Dilemma - Just can't get it right!

    Gee, this is incredibly easy in Lightroom. Go to the Develop module, click the crop icon and select the 1 to 1 ratio. Then go to the Library module and click the export button. You can select the max pixel dimension, resolution and other options. Click export and you're done.

    Photoshop Dilemma - Just can't get it right!

    I would crop the image to get it to a square format and then resize to 600x600 pixels. Note that at 300ppi the print size is only 2"x2". I've never heard of 24 bits.
