Chris says that lights have color and flashes can be regulated to put out different powers of flash, but the cameras can also white balance to the flash if they're good. Flash pictures can look terrible, though. They look washed out, and that's largely due to direction. Mobile phones obviously point the flash straight into your face. That's not a nice light -- it's harsh and flat. Leo says it takes all the contour out, and there's no shadow cast. The size of the light can also determine how good the flash is. But flashes happen so fast, you can't fine tune it.
This week is the "Layers" assignment review:

Today's photo topic is memory cards. Which cards should you buy and do you need the fastest ones? Chris says there's no difference anymore between Compact Flash cards and SD cards performance wise. And the prices have come down. For regular everyday photography, speed doesn't really matter. Video though, a class 10 is a good speed. And they're not that expensive. Chris also treats cards like film. Once they're full, he replaces them like he replaces film. That way he's always using a new card. And then they serve as a backup once he's moved them onto the computer.
This week, Chris has some ideas on how to protect your camera while you're on the road. Chris says having a "ready bag" for your camera is ideal. Minimal in size, and it's protective. But future proof it by getting it a bit larger than you need. A bag sometimes stands between you and your photos when the moment arises. Leo uses a Lowe Pro Sling Bag because it's designed to pull your camera out in one motion. It's a nice way to get your bag out of the way because it's on your back.
Chris heard the call from Caleb who wanted to know about shooting photography with Raw and he decided it was a great topic for today's photo segment. Chris says Raw is a topic that he always gets questions about. On the sensor, there are three color channels, red-green-blue. The sensor collects the light, converts them into an electrical charge and then processes it into pixels with a charge. The charge is what determines the color of the pixel. So you essentially end up with three pictures of the same image in red, green and blue. And then it's mixed up and saved into a Raw file.
Caleb loves photography and he's serious about it as a hobby. But he wants to know about shooting in raw. What is that? Leo says that's where the camera doesn't compress any of the data or process it. It just writes the raw image and it usually covers the entire area of the sensor. But in order to look at it, you have to process it later with a program that can understand the data and render it into an image. But Caleb can also choose to save as JPEG to save on space. But it's also considerably compressed. JPEG is only good if you don't want to post process it and color correct it.
Here's the top three for this assignment, "Upside Down":
Chris said that there were some really beautiful images, but he chose concepts that are very similar.

Caleb has started digital photography as a hobby, and he loves it because it's a non-destructive and positive way to spend his time. Leo says it's a wonderful hobby and with the advent of digital photography and social media, it's gotten even better. Shooters can get better quicker thanks to constructive feedback on the web.
Leo says that there are two kinds of photographers, those who focus on the art and improve their craft with composition, and then gadget hounds that try to get better with technology. Caleb needs to decide what type of photographer he really wants to be.
Bruce is a bush pilot in Alaska. He's looking for a good digital camera that's better than a point and shoot, but not the size of a full DSLR. Leo says the best point and shoot right now is the Sony RX100. It's not cheap at $800 for the MKIII, but it has a 1" full frame sensor, an f1.8 24-70 zoom, and it's tiny. So it's easy to use and provides professional results.
