We tackle some fun stuff this week, including how you intentionally set your exposure, the right image size to use when sharing your images on websites, how to create the miniature/tilt shift effect and how the hell you actually calculate depth of field.

In the video I mention links to a Lensbaby tilt shift lens and a photoshop tutorial to create the tilt shift effect without a tilt shift lens.

Here are the questions answered in this week’s Q&A:

Hello! First of all, thank you so much 🙂 I’ve been interested in photography since I was little, I’ve been moving towards professional photography for a few years now, but I still feel like I’m kind of grasping the basics. So your channel is helping a lot. Now, I have a couple of questions. 1 – How did you intentionally underexpose the backgroud in this picture? 2- And, about the final Image Sizing, what would be the ideal size and resolution for a great quality image, if, for instance, I want to upload it to Flickr, or better, iStock? 3 – Oh, and for the editing you did to be saved in this RAW image, do you have to save this image again, as a RAW file, or does the original file adopt these edits even after you close Lightroom without saving? Thank you in advance! -Rebeca Couto

Why can’t any photographer provide the mathematical evidence in calculating DOF? Yes I understand the circle of confusion will vary between cameras, focal length etc, but photographers must be totally shit at maths or great bullshitters! Lets say we don’t have a device handy that allows us to work out DOF, how do we calculate this without having to take multiple shots using trial and error? How do people design these DOF calculators on mobile devices to give us a near accurate DOF calculation? There must be some sort of formula. I’m a great mathematician who just needs a formula to work with, and I can do vast calculations in my head in no time. Fiddling with DOF apps on my phone is the last thing I want to do especially when I need to take a quick photo. – Gooner Goggles
