A Digital SLR Image Sensor Cleaning Nightmare

Photograph @ Rick Sammon
Cleaning the image sensor in your digital SLR is easy. Many products are available to help you do it, including:

Visible Dust Arctic Butterfly:
Visible Dust Arctic Butterfly 724 Brite Sensor Brush

Sensor Swabs:
Sensor Swab Type 2 (Box of 12)

Eclipse Cleaning System
Eclipse Cleaning System Solution

Blower Brush
Giottos AA1900 Rocket Air Blaster Large (Black)


Built-in sensor cleaning systems also help.


Because dust spots show up mostly in the sky, it's important to keep your sensor clean especially when the sky is in your photograph.


Well my friends, here is an image cleaning nightmare. Originally, I was going to title this post: Nice Guys Finish Last.

Four years ago, I was on a trip and one of the participants asked me to clean the sensor in her digital SLR. I said sure. I used my trusty liquid/swab cleaning system, which I had used many times before with excellent results.

Well my friends, I actually made it worse. I was shocked. I wondered why.

Here's why (or Now You Tell Me!): The day before, the same photographer asked another person on the trip to clean the sensor. In the cleaning process, the person cleaning the sensor blew on the sensor - after eating a bag of pretzels. When I used the swab on the sensor (actually the low-pass filter that is placed over the sensor), I moved microscopic grains of salt across the sensor and created noticeable streaks.

As you may imagine, I don't clean other photographer's sensors any longer.

Just a word to the wise . . .

Photoshop Quick Tip: Color replacement tool rocks!


Here's a quick Photoshop tip: Use the Color Replacement Brush (nested in the Brush tool on the Tool Bar) to change the color of an object or subject in an image.

Below is a shot I took this past weekend on my Plymouth, MA workshop. The workshop was organized by Amy Davies, who heads up the Plymouth Photography Club.

Above is my processed/enhanced image.

I used the Color Replacement Brush to change the color of the model's dress - picking a color (using the Eye Dropper tool and the Color Picker) from the wall.


After changing the color the dress, I softened the picture using the Pastel filter in Nik Color Efex Pro, and then added a Vignette filter, also in Nik Color Efex Pro.

Master Your Flash: Shadows Can Be Your Friend


This post was updated on 8/14. Reader Dwight Atterhold made a good comment re the Canon ST-E2 wireless transmitter. Thank you Dwight.


Here are some thoughts on shadows:

Shadows can be your friend.

Shadows are the soul of the photograph.

Shadows add a sense of depth and dimension to a photograph.

Here are some thoughts on lighting:

The larger the light, the softer the light.

The closer the light, the softer the light.

Above is a shot I took today at my Plymouth, MA workshop. Below is a picture of the super simple lighting set-up. In the photo below, the light is place on on the right. For my opening photo for this post, the both lights were placed on the left.

The workshop was organized by Amy Davies, who heads up the Plymouth Photography Club.

Before going on, a big thanks to Casey Baird, the director of the Fred Astaire Dance Studio in Plymouth, for letting us use her studio - and for helped us out as a great model! The good looking dude is Forrest. Thank you, too!



Gear: Canon 580 EX II placed in a Westcott Apollo softbox fired by my Canon ST-E2 wireless transmitter which was mounted in the hot-shoe of my Canon 5D Mark II. The flash in the softbox was set at full power and on E-TTL.

About the ST-E2: Technically, line-of-sight is required for the Canon ST-E2 to fire Canon Speedlites – because the ST-E2 is an IR transmitter. However, I have found that when working in small rooms with white, bright or glass walls, or rooms with mirrors (this dance studio), the ST-E2 fires Speedlites "hidden" in softboxes all the time. In larger rooms, such as when I was teaching at Photoshop World, the flash sometimes fired. If you want to be 100 percent sure that a Speedlite in a softbox will fire in any size room, use one of the two following devices:

Pocket Wizard
Pocket Wizard FlexTT5 Transceiver For Canon TTL Flashes and Digital SLR Cameras
PocketWizard MiniTT1 Radio Transmitter for Canon TTL Flashes and Digital SLR Cameras

Radio Popper
RadioPopper PX Transmitter Unit
RadioPopper PX Receiver with Antenna and Canon Mounting Bracket

Power Settings
The flash held my the "voice activated light stand," my wife, Susan, was set at 1/3 power.  That 580 EX II was fired through some plastic palm leaves to add some shadows to the stone wall. A blue gel was placed over that flash to add some color to the wall.

Nik Software's Midnight filter in Color Efex Pro was added to add some drama to the scene.

All my camera gear is listed on my gear page.

Below: I just added this behind-the-scenes shot that shows the position of the softbox for the opening shot in this post. Yes, we moved the softbox around the studio for many different lighting setups.
