Eclipse Alert: Total lunar eclipse coming January 20/21, 2019

Super Blood Moon - Image courtesy of NASAOn Monday, January 21, 2019 from 0236 GMT until 0748 GMT there will be a total lunar eclipse. For those in the U.S., I'll translate. The lunar eclipse will run from Sunday, January 20, 2019 at 9:30pm EST until Monday, January 21, 2019 at 2:45am EST.

In North and South America, the entire eclipse will be visible from the penumbral, to partial, to full eclipse and back again. Other parts of the world will be able to see all or much of the lunar eclipse, though much of Asia and Oceania will miss it entirely.

Sensor cleaning update for DSLR and MILC camera sensors

Nikon D200 with lens removed to give sensor access for cleaningIn my NSL Photography Blog article, Essential camera gear protection and maintenance, I discussed the importance of keeping your camera clean to ensure it's ready for your photo sessions and whenever a photo opportunity presents itself. Part of keeping your camera clean is keeping your camera's sensor clean.

Today's DSLRs and MILCs have internal sensor dust removal systems. While they do a credible job, they aren’t 100% effective. Repair shops, and manufacturers offer “professional” cleaning services, but they’re often expensive. Some charge $150 or more, and it can take as long as 3–4 weeks to get your cleaned camera back.

Eventually every interchangeable lens camera will need to have its sensor cleaned, as every time its lens is changed, dust and dirt in the air freely enter its sensor compartment. At times, it may be necessary for photographers to clean the sensor themselves rather than wait for a professional cleaning, particularly when in the field.

What do I do about those dust spots on my digital photos?

Zeeion BlowerIn recent months, numerous readers sent emails to me about dirt and dust problems on their photos. They had cleaned their lenses, but the spots remained. They examined their DSLR’s sensor/filter and saw little specks of dirt, and asked what they should do.

You can generally remove spots during post processing, but it’s better to not have the problem to start, as sometimes “Photoshopping” doesn’t work particularly well.
