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.

Choosing Lenses for Your DSLR Travel Kit, Part II

AF-S-VR-Micro-NIKKOR-105mm-f-2 8G-IF-EDIn Choosing Lenses for Your DSLR Travel Kit, Part I, I discussed travel photography's many challenges including luggage weight limits, number of luggage pieces permitted, locations with unknown restrictions, bad weather when you least expect it, and others.

I discussed the two major factors that influence which lenses you put in your photo travel “kit,” travel weight and volume, and the varying conditions, limitations and circumstances of your destination's photographic opportunities.

This week, in Part II, I will discuss specific lens choices for three particular travel locations and types of travel you might choose to take which you can use as exemplars.

Lenses for Travel Photography - Part VI (Special lenses and lens accessories)

Cutaway of Zoom Telephoto LensThis week in Part VI of my seven part series about lenses for travel photography, I discuss special lenses and lens accessories to consider when choosing lenses for travel. The series is primarily meant for SLR and DSLR camera users, who can attach a variety of lenses to their cameras to support their creativity, and suit the needs of their photographic opportunities.

It’s important to note there are many more lenses and lens accessories available for your consideration than I will discuss below, but the ones I have chosen have utility during travel, and are carried by some travelers, according to their needs.

Three lenses possible lenses for travelers include: fisheye, perspective control, and teleconverter.

Lenses for Travel Photography - Part IV (Lens choices for travel photographic opportunities)

Cutaway of Zoom Telephoto LensThis week in Part IV of my seven part series about lenses for travel photography, I’ll discuss choosing lenses for your travels. The series is primarily meant for SLR and DSLR camera users, who can attach a variety of lenses to their cameras to support their creativity, and suit the needs of their photographic opportunities.

There is a large variety of lenses: wide angle, normal or standard, and telephoto lenses, wide angle zoom, standard zoom, and telephoto zoom lenses, and don’t forget there are also zoom lenses which go across the categories as I discussed in Part III of the series. As the great American jazz and popular music singer, Peggy Lee asked in one of her famous songs, “Is that all there is?,” in the world of photographic lenses, the answer is, no.

There are also super telephoto lenses, and super telephoto zoom lenses, as well as specialty lenses such as fisheye, macro (close-up), perspective control lenses, and selective focus lenses.
