How To: Give Your Photos a Surreal Effect by Stacking Negatives

Want to add cool effects to your photos without using expensive equipment? Photographer Laina Briedis created these gorgeous shots by stacking 35mm negatives of starry or cloudy skies on top of photos of people to give them a surreal, dreamlike effect. There are a few ways to go about it. Laina explained to PetaPixel that you can do this with or without a darkroom. If you have access to one, you can expose two negatives at the same time by stacking them, or expose them separately onto the sam...

How To: Jump Start a Car

We've all been there before: We're in a hurry to get somewhere (often in bad weather), so we get in the car, turn the key in the ignition and.....WHUH! WHUH! WHUH! The darned battery is dead! After a stream of choice expletives (that is, if you're anything like me....;o)), we open the trunk and take out the jumper cables - but what if we don't know how to use them? Even if we do, we can often forget such things in crisis situations when we're pressed for time.

How To: Deal with Toxic and Belligerent People

Unfortunately, toxic and belligerent people are not as avoidable as we would like for them to be. They show up in our work place, schools, neighborhoods—sometimes even within our own circle of friends and family members.
