  1. Cleaning the SensorOn Your DSLR(and the rest of the camera as well…) Presented by N. David King

  2. Cleaning a DSLR Sensor Is Cleaning Really necessary? • Well… it depends… • Do you like those amorphous dark shapes in your images and think they are conceptually creative? • Do you enjoy “spotting” more than editing? • Do you like spending increasing amounts of time cleaning your shots instead of making them better? • Do you like spending $50 to have someone else clean it for you? • If the answer is “Yes” then you don’t need to go on… © N. David King

  3. Cleaning a DSLR Sensor Can Cleaning be avoided? • Sure… • If you never take your camera out and use it. • If you never remove a lens and it is “O” ring sealed to the body. • If you never shoot and change lenses in anything other than a hermetically sealed “clean room.” • If you do any of these things, sooner or later you will need to clean your camera and sensor… © N. David King

  4. Cleaning a DSLR Sensor Is Cleaning Dangerous? Cleaning a sensor is like cleaning a lens… If you do it correctly you could do it daily and never harm the camera or lens. But if you do it wrong you could damage the camera, lens, or sensor very quickly. This presentation is all about doing it correctly! © N. David King

  5. Cleaning a DSLR Sensor Camera/Sensor Cleaning Workfow • There is a proper workflow for cleaning your camera and sensor… • Get the right equipment and supplies and have them handy to you can work quickly and easily. • Work from the outside to the inside. • At each stage, start with the least intrusive and work toward the more intrusive only if necessary. © N. David King

  6. Cleaning a DSLR Sensor Camera/Sensor Cleaning Supplies • Here are the proper supplies to have on hand. You’ll need… • Air: 2 kinds © N. David King

  7. Cleaning a DSLR Sensor Camera/Sensor Process • A word of caution on using canned air... • Canned air is a very powerful tool but must be used correctly. • Never use a can that has been shaken or disturbed. Let it settle and rest for a few minutes before use. • Never put the nozzle very close to the surface • Never aim the nozzle directly at a surface • Never aim the nozzle at your skin or someone else’s © N. David King

  8. Cleaning a DSLR Sensor Camera/Sensor Cleaning Supplies • Here are the proper supplies to have on hand. You’ll need… • Air: 2 kinds • Brushes: 2 kinds • Lint Free Pads • Cleaner • Swabs for YOUR sensor © N. David King

  9. Cleaning a DSLR Sensor Camera/Sensor Process • At each stage the following workflow will be used… • Blow off loose particles • Brush/lift off more stubborn particles • Use cleaner as a last resort and use it properly. © N. David King

  10. Cleaning a DSLR Sensor Camera/Sensor Process • Camera BODY Exterior • Use canned air AT AN ANGLE to blow off dust and dirt. • Pay attention to nooks and crannies and small areas where it is hard to reach e.g. card slot, jacks, view finder area, etc. • Use the normal brush to dislodge anything left and then the air again to remove it. • Use only a DAMP towel (never a “wet” one) to wipe the body of the camera. A damp cotton swab will help get in some tight areas. © N. David King

  11. Cleaning a DSLR Sensor Camera/Sensor Process • Camera LENS Exterior • Use canned air AT AN ANGLE to blow off dust and dirt. • Pay attention to nooks and crannies and small areas where it is hard to reach like focus rings, etc. • Use the normal brush to dislodge anything left and then the air to remove it. • Use only a DAMP towel (never a “wet” one) to wipe the body of the lens. © N. David King

  12. Cleaning a DSLR Sensor Camera/Sensor Process • Camera LENS Glass • Use air from Rocket Blower AT AN ANGLE to blow off dust and dirt. • Pay attention to nooks and crannies and small areas where it is hard to reach like around threads. • Use the normal brush to dislodge anything left especially in filter threads and then the air to remove it. • Use a charged Nylon Brush for any remaining particles on the glass.

  13. Cleaning a DSLR Sensor Camera/Sensor Process • Camera Lens: Glass • Use air from Rocket Blower AT AN ANGLE to blow off dust and dirt. • Pay attention to nooks and crannies and small areas where it is hard to reach. • Use the normal brush to dislodge anything left especially in filter threads and then the air to remove it. • Use a charged Nylon Brush for any remaining particles on the glass. (Charge with canned air) • Use only a lint-free pad with a drop of cleaner in a spiral motion on the glass surface. © N. David King

  14. Cleaning a DSLR Sensor Camera/Sensor Process • Camera LENS Glass • CAUTION • Do Not put liquid cleaner directly on the glass. It can remove the lens coating. • Do not use so much cleaner that it pools on the glass or leaves streaks. If it streaks you are using cheap cleaner and/or you are using too much of it. • DO NOT USE commercial glass cleaner such as Windex on your lens. It WILL damage the coating. It may cost less than optical cleaner but the price of a new lens will kill that savings. © N. David King

  15. Cleaning a DSLR Sensor Camera/Sensor Process • Camera Body: Mirror Chamber • Use air from Rocket BlowerAT AN ANGLE to blowoff dust and dirt. Hold camera upside down to let particles fallaway from body.. © N. David King

  16. Cleaning a DSLR Sensor Camera/Sensor Process • Camera Body: Mirror Chamber • Use air from Rocket Blower AT AN ANGLE to blow off dust and dirt. Hold camera upside down. • Pay attention to nooks and crannies and small areas where it is hard to reach. • Use the normal brush to dislodge anything left especially in the lens mount and then the air to remove it. • Use a charged Nylon Brush for any remaining particles on the glass. (Charge with canned air) • Use only a lint-free pad with a drop of cleaner on the mirror and Prism surfaces. © N. David King

  17. Cleaning a DSLR Sensor Camera/Sensor Process • Camera Body: Mirror Chamber • If you can see particles when looking through the viewfinder they are most likely either on the mirror or prism • Caution on cleaning the Mirror… • The mirror is silvered on the outside and some cheap lens cleaners can remove the silvering or particles can scratch it. © N. David King

  18. Cleaning a DSLR Sensor Camera/Sensor Process • Camera Body: Sensor Chamber • OK, here is the heart stopping part so lets back up and consider what is really about to happen… • It is important to realize you are not actually going to be mucking around on the surface of the sensor. © N. David King

  22. Cleaning a DSLR Sensor Camera/Sensor Process (Continued) • Camera Body: Sensor Chamber • To get into the sensor chamber you need to open and lock open the mirror. • Menu options. • Auto versus Manual Cleaning. • Use a newly charged battery or plug you camera into the AC adapter if it has one. • Get everything ready for use to minimize the time the sensor chamber is exposed in order to limit the reintroduction of NEW dirt and dust. © N. David King

  23. Cleaning a DSLR Sensor Camera/Sensor Process (Continued) • Camera Body: Sensor Chamber • With camera upside down blow out the sensor chamber with the rocket blower just as you did the mirror chamber. • Do a visual inspection of the sensor with a sensor scope, magnifying glass, or just against a good flat light reflection. • If you see something on the sensor use the blower again. • Use a sensor scope or do a shot test to see if you got it all. • If it is clean then stop… if not then go to the next step. © N. David King

  24. Cleaning a DSLR Sensor Camera/Sensor Process (Continued) • Camera Body: Sensor Chamber • If the blower did not remove all particles, now proceed to LIGHTLY use the charged nylon brush. © N. David King

  25. Cleaning a DSLR Sensor Camera/Sensor Process (Continued) • Camera Body: Sensor Chamber • If the blower did not remove all particles, now proceed to LIGHTLY use the charged nylon brush. • Inspect the sensor again with scope or test shot. • If it is clean then stop, close the mirror and put camera away. • If there are still particles showing, you might recharge the brush and go again but if that fails to remove the particles then now it is time to use the sensor swabs. © N. David King

  26. Cleaning a DSLR Sensor Camera/Sensor Process (Continued) • Camera Body: Sensor Chamber • Using the Sensor Swabs • Use a SINGLE drop of solution on the tip of the swab. It should be damp but NOT WET. • Make a single pass in each direction and then toss the swab away. © N. David King

  27. Cleaning a DSLR Sensor Camera/Sensor Process (Continued) • Camera Body: Sensor Chamber • After using a sensor swab, inspect the sensor again with scope or test shot. • If clean then close mirror and put camera away. • If not, repeat. • If you KEEP the camera clean you will generally end up with the sensor clean after only the blower or brush. © N.
