Doctor Bird uses the focal plane point symbol all the time, when he's taking macro images of butterfly eggs. He uses a tape measure and that symbol to get really precise with how far away his camera needs to be.
Chris says there are a lot of symbols and buttons on cameras, some standardized, some specialized. Here's a few:
Leo says yes, all Android phones can do this. He just needs to get a USB cable, either USB Type A or Type C depending on what his computer has. A Windows PC should be able to mount the phone as a drive, but he may need to get software for it if he's on Mac. He can look for "Android File Transfer Manager" which is a free program that allows the Mac to see the Android device.
Chris says that Kodak has reengineered Kodak Ektachrome to make it safer to develop and they are selling it again. They are also working on a Super 8 camera with Digital Preview. Chris says he'd beware of Kodak digital products, but the film is the best.
Chris also has some tips when traveling to the desert with cameras. Bring a backup body if you can. You should also bring canned air or a blower to clean off the sensor or lens itself. A microfiber cloth is also good for the lens. Lastly, when you get back, have your camera cleaned (called CLA clean, lube and adjust).
Chris is back in the US, visiting the Kodak headquarters in Rockwell, NY. But he wants to talk about his trip to Morocco.
See his pictures here. Look for the images of lightning in a cloud, camels at sunrise, and an indoor Moroccan swimming pool. Chris took around 3,000 images to get 20 perfect shots. So Chris spent a lot of time weeding out the best images and tossing the rest.
James is looking for an app that will help him to edit the metadata that is in his still images. He wants one that will allow him to put in a description and then search for keywords. Leo says that all photos have extended information tags, or "EXIF" data. There's also a standard called IPTC that does titles and descriptions. So it can be done. Most photo library programs, like Adobe Lightroom will do it. There's a free one called Photo Me.
Paul's daughter dropped her Sony A6000 camera lens into the sand and the repair facility wants $141. She can get a new one for that, which is "bulk international lens." Leo says that chances are it's a grey market item, which comes with no warranty. If that was a camera, Leo would say no. But with a Lens, it's less of an issue. One thing she'll have to be careful of is that more than half the stuff sold on Amazon isn't sold by Amazon, it's just fulfilled by Amazon. So she does run a risk if Amazon doesn't ship it. If it's a reputable company with decent ratings, it should be OK.
Jay's daughter wants to get into photography. What's a good, entry level DSLR? Their budget is $300 to $500. Leo says that it's a great idea to get her a kit zoom lens, but there is a debate that people should learn with a 50mm first before going with additional lenses.
