Basics: Setting Up Your Tripod

Hello folks. I’m not going to get all parochial on you here, but in teaching workshops and rubbing shoulders with other photographers I see lots of people struggling with setting up their tripods – some of them don’t even know that they are struggling. If it makes you feel any better, I once set up my tripod in such a way that it flopped over and snapped a $1400 lens in half. I’ve also witnessed a fellow photographer’s rig topple over, fall on to rocks below and in the process smash his lens to smithereens and create a hole in his camera body. Need more motivation?  Six students had their tripods topple over when shooting at an event where there was gusty wind. None of them had done what we recommend below.

If you’re sure you know how to solidly set up your tripod and how to prevent an expensive catastrophe, well, you probably stopped reading when you saw the title of the article.

Using a tripod correctly in terrain like this is a valuable (sanity preserving) skill

Still here? There is no substitute for using a sturdy tripod as we described earlier. However an improperly set-up tripod will give you a false sense of security.

Lets be sure we have terminology straight:

Feet: The part of the tripod that touches the ground – the bottom of the legs.
Legs: The (often telescoping) section of the tripod. Legs are made secure using
Leg Locks: which are of two general types: flip locks and screw locks (shown). We prefer the latter.
Leg Pivots: The upper side of the legs attach to the BASE where the legs can be made to pivot inward or outward. Usually there are options for specific pivot angles.
Tripod Base: The leg pivots are on the underside of the base.
Center Column & Center Column lock: If the tripod has an extensible section separate from the legs, it usually fits through the base and has a lock to secure the center column height. Some center columns also have a hook at the bottom (as shown).
Base Plate: The top surface of a center column (or the top surface of a base) to which the head is attached.
Head: The purpose of the head is to allow the camera to rotate and tilt. There are two principle types of heads: ball heads (shown) and pan/tilt heads.
Quick Release Clamp: the upper surface of the head usually has a clamp/plate system to make it easy to mount and unmount a camera. Arca-Swiss is the most popular clamp/plate system.
Quick Release Plate: attach securely to the camera and is held by the QR clamp.
Camera: the reason you have all the preceding stuff.


The Basics

Vertical: Your tripod should be vertical, specifically the center column (if you have one) should point straight up and down. The more vertical, the more stable the tripod is. By vertical, we don’t mean perpendicular to the ground – the ground may be sloping or irregular. The most common mistake people make is to set their tripods up so that it leans toward them.  Before you put your camera on your tripod, walk around the whole thing (safely) to judge the verticality.  You can even use a level (e.g. a smart phone app) against the center column to be sure it is vertical. Some tripods have a bubble level on the base – and some heads have a level on their base – that you can use to be sure your tripod base is level.

Notice tripod in the distance is leaning to the right (click for a bigger view)? That’s wrong!

Level: For many reasons, you want the base to be level (perpendicular to vertical). If your tripod is vertical, the base will be level. A level base makes panning (and thus panoramas) more accurate. If the base isn’t level rotating the camera may change the center of gravity causing wobble – or worse.

Legs: There are two adjustments here: the leg length and the leg spreadDO NOT fully extend the leg lengths – unless you are on flat, level ground. Adjust the legs so the base is level.

  • When on a slope, put two legs on the downhill side of the slope and one leg on the uphill side.
  • Place two legs at the front (that is where the camera is pointing) and one leg toward the rear.

If these two goals conflict, prefer two-legs downhill. A single leg at the front may intrude into a wide-angle shot. Most tripods have adjustable leg spreads. Each leg can form a medium, moderate or severe angle to the base. On irregular terrain, you may find that stability requires setting one or more legs at a different spread and different lengths. E.g. one leg is kept short at 90 degrees to allow that leg to rest on a boulder while the other two are more vertical. In a multi-segment tripod leg, the wider leg segments are more stable than the narrower ones, therefore:

  • Extend the wider leg segments fully before extending the narrower leg segments.

TIP 1: We find the screw-type leg locks to be the most secure and easiest to adjust. What we do is to grasp and loosen all the leg locks at once by a quarter turn. Fully extend all sections. Tighten the top locks fully (and middle locks – if you have 4 segment legs), then loosely tighten the smallest leg locks. When setting the tripod down you can gently push down each of the legs until it is vertical and level, then fully tighten the lower leg locks. Minor fine tuning can be achieved by loosening the upper leg locks.

  • If in windy conditions, set the tripod lower than normal and spread the legs wider. Also weight the system more heavily (see Weight, below).

Center Column (and tripod height): DO NOT extend the tripod fully just because you can. Extend the column as little as needed. The center column is useful for fine-tuning the height of the camera, but it raises the center of gravity and makes your tripod less stable. Likewise making your tripod as tall as possible makes it easier for gusty wind or and inadvertent bump to topple everything.

Tie-Stake Useful in some terrains

Weight: We HIGHLY recommend adding weight to your tripod. Many tripods have hooks on the underside of the base or on the bottom of the center column. We regularly hang our camera bag from that hook. But beware: if your camera bag is too light or bulky, you may end up adding a sail that catches the wind and creates instability. Some people bring weights, or bags they can fill on site with rocks or sand. But there are yet two more tricks you can employ:

  • Hang your camera bag so that it nearly touches the ground (by using a lower tripod position, or a strap between the bag and the tripod). Then place rocks or logs around the bag to keep the bag from swaying. Add heavy things in to the bag if you need more weight.
  • Bring a tie-down stake and a bungee cord. Screw the stake into the ground below your camera and snug the tripod hook to the stake with a bungee cord.

 

Straps: If you have shoulder or wrist straps on your camera we recommend using removable ones OR use twist ties or velcro wraps to secure the straps to your tripod so the straps do NOT catch the wind (or nearby objects). Shoulder straps can become like sails and even if they don’t catch enough wind to topple your tripod, they can induce vibration. We really like OP/Tech products, by the way. They are well designed and have never failed us.

Tip 2: One way to practice setting up a tripod is to do it indoors. Create un-even scenarios by resting one (or more) of the legs on a chair, wastebasket, etc. Practice getting the legs adjusted in a way that keeps the center column vertical and the base level.

Safety Checks

After setting up your tripod as described above, you can and should test the stability of your tripod/camera. WHILE HOLDING ON TO THE CAMERA STRAP(s) do each of these checks:

  1. Pull down on each of the legs gently. Make sure they don’t collapse/fold.
  2. After clamping the camera to the head and tensioning the head. Hold the camera snugly and try wriggling the camera out of the clamp. Watch carefully for wobble and hold on securely in case the camera does come out of the clamp.
  3. Hold the camera, release tension on the head and let the camera gently flop. Make sure that when the camera flops the system doesn’t topple.
  4. Leave the camera in its flopped state and rotate 360 degrees checking for wobble.
  5. Repoint the camera, tighten the tension and gently bump the camera. Make sure there is no wobble.
  6. Bump each of the legs. Make sure the legs don’t become dislodged and the spread doesn’t change.
  7. Take one more lap around your camera checking for verticality and possible instability – e.g. a log, tree branch, stick or rock that could bump your tripod.

Is all of the above really necessary? Well, no. You don’t have to do any of that… unless you want to protect your equipment and take nice stable photos.

Exploring Night Photography: Lesson 6 BEST TIPS

Band of Techies by Steven Christenson on 500px.com

Twilight Panorama of the San Francisco Bay

Last week we talked about photo processing.  This week is the last week of the in-person course.

The topics covered in class included Astrophotography, suggestions on what equipment NOT to get for Astrophotography. We also discussed the limitations of Lightroom and Photoshop (see Lesson 5) because we did not cover them all in the last class.

To conclude our lesson series we present our greatest tips.  Many of the tips you may be familiar with – especially if you have been with us on a workshop. Some tips will be a surprise.

Our Best Night Photography Tips

  1. Shine a bright flashlight through your viewfinder at night and it will show you what is in your shot. Much easier to figure out where the edges of your frame are when it is too dark to see well.
  2. A flashlight will not illuminate the sky where your shot is constrained by your lens, but a bright green laser through the viewfinder can accomplish that!
  3. Put glow sticks or LED slap bracelets around your tripod at night. Not only can you find your gear easily, but others are less likely to trip over it.
  4. Have a bluish LED light that you need to make less “cold”? Bounce it off the palm of your hand… or a warm colored shirt.
  5. Want to see well in the dark? Don’t wear a head lamp! Shadows and contours are hard to see when the light is coming from close to your eyes. Instead keep a DIM light at waist level. Bright lights ruin your night vision. And headlamps make it painful to talk to one another… you ruin their night vision when you look at them.
  6. Before you spend the effort traveling for night photographs, consult the weather and the moon phase.
  7. It is astonishing how much you can pre-plan a shot without having to go the location… hint: learn to use Google Maps + Street View!
  8. Don’t overlook the hundreds of tips we have for you here on this site… the search box is your friend.
  9. Dark skies are good… but better is to know which direction you want the sky to be dark so you can make the right compromises.
  10. Sometimes being behind a hill is a great help to prevent unwanted stray light.
  11. Want to photograph (or see) the best part of the Milky Way? You need to know when it is up. A planisphere (rotating star chart) is your best bet.
  12. Velcro is a great way to keep things handy and secure on your tripod. Velcro your intervalometer to your tripod.
  13. Lens hood – use one all the time to protect your lens and prevent stray light from causing glare.
  14. Do not use any filters – especially not a clear or “ultraviolet” filter. All filters make your image less desirable by causing extra surfaces that can reflect light and cause glare. Our only exception to this rule are 1: polarizing filters – which are useless at night, and 2: a filter to seal your lens in really nasty environments like rain and blowing sand.
  15. Test your tripod stability before you move away from it. If your tripod is secure, take a few steps back and make sure the center column is vertical.  It is common to set a tripod up so that it leans in a way that makes it vulnerable to a fall.
  16. Another tripod tip: on a hill or slope, put two legs on the downhill side, one on the uphill side.
  17. Short straps (or no straps) on your camera is better for stability if there is any wind at all. We have personally seen cameras thrown over by wind gusts.
  18. Do not cheap out on a tripod. A sturdy tripod is more valuable for night photography than a “better” camera.
  19. The histogram is your friend. Be sure to check it before you conclude your shot is a good one.
  20. If your tripod has a hook below the center column hang your camera bag on it for even more stability. Be sure you’ve taken out all you need before you start shooting. Oh, and this may NOT work well if it is really windy or your pack is light.
  21. Study the place you plan to go during the daylight. It is not fun falling in holes or stepping on nasty things while wandering in the dark.
  22. Take a friend along for added safety, camaraderie and comfort. Also you do not have to outrun a bear, you just have to outrun your friend. 😉  [Do NOT try to run from a bear, by the way. That just makes you look tastier]
  23. A ball head works a lot better for night photography than a pan-tilt head. But get a sturdy head! It is useless having a sturdy tripod with a head that can not stay put.
  24. If there is anyone who may care: tell where you are going and when you expect to be back. Stick to the plan, too.
  25. Do not assume you will have cell service – some of the most amazing places to photograph have no cell coverage at all. Oh, and your battery might die.
  26. Overshoot. It is so much better to have two or three times as many shots as you think you will need than to find out you did not even get one quite right.
  27. When shooting sequences or panoramas… use your lens cap between sets so you can figure out when one set ends and another begins. Take it one step further and do what we do: use your hand forming an E, N, W, or pointing down to indicate the direction you are facing when you take the shot.
  28. Dark gloves make great “emergency stray-light reduction” devices – and they can keep your hands warm, too.
  29. It will always seem colder at night than the temperature might indicate. Dress in layers.
  30. Planning to leave your camera shooting for a long sequence and walk away? Use a GPS to record the camera location (you can do this using most cell phone map software, too).
  31. Respect people and their property. Ask for permission. You may be amazed how much farther courtesy and thoughtfulness will get you than being an intentional trespasser.

Exploring Night Photography: Lesson 3 – Gear

Two weeks ago in class we covered basics (what is a photograph, using manual settings) Last week we learned a bit about noise, and its primary causes – temperature being the principle problem. And we explored different creative directions under the umbrella of night photography. We also got outside under a half-full moon (first quarter) and shot on campus. And learned a little about the night sky.

This view is southwest. From left to right are Canis Major, Orion and Taurus. The moon is off the top edge.

This view is southwest. From left to right are Canis Major, Orion and Taurus. The moon is off the top edge. The glow in the lower right corner is the glow bracelet on one of the student’s tripods. The sky remains blue due to the moonlight. Settings for this shot are ISO 800, f/2.8, 10 seconds, 20 mm on Canon 5D II.

Now it is time to talk about gear. Fortunately we already wrote a nicely detailed article about gear. Take a look here. We even updated it recently.

Too busy to read the details? That’s a shame, but here is the super quick summary in order of importance:

  1. GOOD tripod.
  2. Night photography friendly lens (wide angle recommended)
  3. Decent camera body with an optical viewfinder. Full frame preferred, but not necessary.
  4. Layered clothing and good shoes, including lightweight gloves (G) – and heavy gloves in cold season.
  5. Sturdy camera bag
  6. Extra batteries and memory cards
  7. An intervalometer (1), and extra batteries (2)
  8. Headlamp (B) and flashlight assortment (C, 3, 6)
  9. Other needful things: clear shower cap (A), lens cloth, hand cloth.

What About Other “Gear”?

MiscGear
Here is what is usually in our bag besides the camera gear.

  • (H) Glow bracelet/stick to mark the camera location (we have just started experimenting with other methods, too, like the LED band (4).
  • Hand warmers (F and 5) and rubber bands (G) for dealing with dew formation
  • Creative lights – bulbs, keychain lights,  and cord (3, 4, 6, 7, 8, 9)  Item 7 is a green laser pointer.
  • Insect Repellant  (E)
  • Gaffers Tape – flat black duct tape (L). We don’t take a whole roll though!
  • A smart app that shows the positions of the stars, planets, and bright satellites. Also helps if it shows meteor showers.
  • A smart app that shows the location(s) of sunrise, sunset, moonrise and moonset.
  • A game or two on the smart phone to pass time.
  • An external battery to keep our smart phone juiced (5) and the appropriate matching cord.

Before We Leave We Also Use the Following

  • A star map (planisphere). On our desktop, we favor Stellarium, but it is a little geeky to use well. On iOS we like Sky Safari, Star Map.
  • Weather prognostication tool
  • Sunrise/set Moonrise/set predictions.

This Week’s Homework

  1. Use the light you were given in class to write a message or draw an image in light.
  2. The moon is full, if you didn’t work out settings for capturing the moon. Now is another chance. If you did work out the settings, compare them to your last shot when the moon was half-full. Notice anything?
  3. Find a way to make a strong white flashlight a different color. Use the colored light to illuminate your foreground. Your light may have to be really bright to compete with moonlight.
  4. If you are using a “white” LED flashlight, you’ll notice it is significantly cold (blue). Can you think of a way to make it a warmer color?
  5. Is there any “Other Gear” listed above that intrigues you? E.g. what can you use Gaffers Tape for?

Catching the Moon Simplified

Freedom Gazes at the Moon [5_055475-7deB]

Freedom – the statue at the summit of the Nation’s Capitol – Gazes at the rising Moon

One of our popular webinars is Night Photography 111: “Catching the Moon (and the sun)”. The next webinar is April 2, 2014, by the way. Long before the many tools that now exist to help solve for moon+landmark alignments I began working on a tool I call the MoonChase Tool. As snazzy tools came into being like Stephen Trainor’s Photographer’s Ephemeris, SunMoonCalc, MoonSeeker, and many more, I neglected the MoonChase Tool and focused more attention on the Advanced Stacker PLUS. In fact, after Google discontinued the V2 map interface upon which MoonChase was built the tool languished for about a year and a half. I also stopped teaching how to use it in the NP111 Webinars. But, I kept finding that all existing tools just didn’t do what I needed, so I resurrected the MoonChase tool. I ported it to the newest Google Maps API (V3), and I then added some of the features I had on my wish list.  I’m really proud of what the tool can do now. And I have some fiendishly clever plans for the future of the tool, time permitting, of course. Operationally the MoonChase Tool is simple. The hardest part is coming up with the location where you want to stand and the landmark you want to face. If you know that there is a sightline to a landmark in the distance you can fire up MoonChaseTool and in 3 steps know when to go to get the moon or sun behind your landmark!  That’s right. You paste, paste, click and click. Or drag, drag and click. We cover how to cook up good locations in the Webinar. How do you get your hands on this tool? We’ll tell you! If you’ve attended a NP111 webinar with us, or purchased the video and notes you already HAVE access through the “private page” (you did save the password, right?).  You’ll find the link to the MoonChase Tool on the private page.  Or sign up for our webinar which includes the notes and video AND access to the MoonChase Tool – and you don’t have to wait for the webinar, we send you all the links when you sign up (see below). The tool isn’t especially pretty, we admit that.  But it is pretty EASY to use and it works even from your iPad or tablet as long as you have internet access.

3 Steps to Moon (or sun) catching

3 Steps to Moon (or sun) catching. And there is more: you can check the view with Google Street View, and even check the weather with the weather button.

After clicking “Moon” you get the report thanks to Jeff Conrad’s SunMoonCalc tool. Be careful to be sure it selects the time correctly. Below it’s off by an hour due to Daylight savings time.

What Problems Does the MoonChase Tool Solve?

The tool was designed to do the trigonometry for you. Did you know there is trigonometry involved?  Don’t worry, you don’t have to know trigonometry or math.  Nor do you have to know about spherical coordinates, azimuths, altitudes or the three different kinds of twilight.  All you have to know is where you want to stand, and what you want to be in your picture. Drag the markers around on the map and click one of the Solve buttons. OR use the tool in concert with The Photographer’s Ephemeris.

What Do I Need to Know to Do?

It’s very helpful to be able to do the following things: grab GPS coordinates from Google Maps and/or Photographers Ephemeris.  We teach how to grab GPS coordinates in the course. You’ll also want to know how to find heights of your favorite landmarks. Google comes in really handy for finding heights of buildings!  One more thing you’ll want to verify is whether you can See the landmark from the place you want to stand. Again, we describe 4 different ways you can do that in the webinar. The rest is dragging and clicking!

How Long Will it Take?

If you already have the coordinates, it will take perhaps thirty seconds – or not even that long.

I WANT THAT! How Do I Get It?

Easy: Sign up for the webinar and you’ll get immediate access to the private page plus the videos and notes. If you’ve already taken the webinar, go to the private page and you’ll find the link in the Resources section.  Or as a prior purchaser, just sit tight as we’ll be sending the new materials out to all prior purchasers over the next 3 weeks.
