Chris Marquardt and Volumetric Light

Chris Marquardt

Episode 1765

Chris joins Leo to talk about volumetric light. Light can have a shape and you have to be at the right place at the right time to capture it. So it helps to always have a camera with you. It also takes down contrast, making blacks less black. A point light source and some fog or mist contribute to it. It's also known as "God rays." It's why concerts tend to use fog machines to create volumetric light on stage. Dust is another contributor to volumetric light. It can be seen in caves and canyons when light emanates from a hole.

How Can I Move Photos From My Old iMac to My New iMac?

iMac

Episode 1765

Adam from Putnam Valley, NY

Adam has an old 2007 iMac that still runs well, but it's not very good for the Internet. He wants to use it as a secondary computer next to his newer iMac.  Leo says to make sure both computers are attached to the same iCloud account. That will make sure that the older Mac is synced properly. Leo also said that it's likely running iPhotos, the older version of Apple Photos. So it may have iCloud turned off. So turn that on. 

Chris Marquardt: Layers

Episode 1763

Today, Chris joins Leo to talk about using layers in photography. Layers make depth. So if you consider foreground, middle, and background as layers, you can create depth in your photo composition, making your photographs more interesting. Lenses can also make a difference. Layers in telephoto will look differently than layers with a wide-angle. Wider apertures flatten out the layers, while smaller apertures can create bokeh (out of focus background): depth of field. The photographer can also lead the eye with focus to be sharper and in focus, while the background and foreground are not.

Chris Marquardt: Visual Bokeh

Episode 1756

Chris joins Leo to talk about using Bokeh (boke-eh) to make a visual impact in your photography. Bokeh is the out of focus background in your image. Bokeh helps put the viewer's attention on the subject, which is in focus. Bokeh can also set a mood, with lights out of focus. It can also be used to disguise a busy background. Bokeh is accomplished by opening up your lens all the way (the lowest f stop setting). And the faster your lens, the more bokeh you can achieve. 

Chris Marquardt ... Winter Photography

Episode 1754

Today's photo topic is winter photography. Here's the gallery for it:

Colors tend to look "cooler" in Winter scenes because of the skewed white balance. So post-processing your Winter photos to make them "blue" can make them look better. You can also dial your exposure compensation to +1 or so to compensate for the skewed white balance that can make your photos look grayer than they appear. 

How Can I Batch Process Thousands of Images?

PixInsight

Episode 1748

Richard from South Texas

Richard is a night sky photographer, and he uses photoshop to create time lapses. He would like to apply the same photo settings to thousands of images he has already taken. Is there a batch mode that can do that? The chatroom says that there is a tool called PixInsight (Windows, macOS X, Linux), which has scripting that can perform that task. There's also a handy color management tool. There's also LR TimeLapse.
