Winter Photography Tips and Tricks - Part 2

Here are some more useful tips for proper metering in tricky situations

1) Meter off the blue sky

If you have a clear blur sky over you, a very good approximation of average metering can be obtained by metering off the sky.

2) Metering off your Hand

Your hand can also act as a good exposure metering source. if the same light falling on the object you are planning to photograph is falling on your hand, then you can adjust for a proper exposure of the palm of your hand. Its important to remember that you need to open one stop more of light after you have set proper exposure for your hand. The easiest way achieve this by adjusting the shutter speed. If you see 1/60 sec as a proper exposure on you hand, the opening one stop more will give you 1/30 sec. Keep Aperture constant here. If you use the manual mode, you should find this easy. Another way is to keep increase aperture by one stop. This will impact the depth of field and therefore not suited in certain situations (same can be said with shutter speed also). If you are adjusting the aperture, then if if you need to open op one stop, then go to the next lower f number. If the current aperture is f5.6, then move to f4. The color differences in skin wil not make major changes to your exposure.

Metering Snow - Winter Photography Tips and Tricks - Part 1

Metering is a very complicated subject and i am still learning the basics of it. All camera meters try to expose the subject as a medium tone/ Average exposure. In many cases that will work. Many of the objects that we deal with in real life have medium tone.

All light meters are calibrated to 18% grey or Average. What this means is that when you expose for an average subject you have a very good chance of getting the metering right. But consider a more complex situation like Snow or a Black gorilla. These are not average subjects and the light meter will be way off if it tries to meter them. If you take pitures of snow, you may notice that the snow itself appears grey and not white as u see it. This is because your camera light meter is trying to expose the snow as 18% grey and not as white.

In these situations its best to have a 18% gray card with you. Meter the gray card on the same light that falls on the snow. This is very important. Adjust your exposure to get the right settings and shoot. This will give you the correct exposure you need. Snow will start to look white again.

18% grey cards are very inexpensive and are available in most photo shops.In addition to exposure control, these grey cards also help you to maintein proper white balance in your picture. If you have pictures with tint of yellow or blue tint, then this could be a very good solution to these problems. What you need to do is take an additional photo with the grey card on the same light. And the in post processing, set the custom white balance to the grey card's color. This will correct any color deviations in your picture in one click.

Here are some highly rated ones from Amazon.

If you are serious in getting proper color and exposure in your pictures, then you should definitely invest in one of these.

Again you may not be able to carry these cards everywhere you go. Here is a good trick in those situations. This will help with correct exposure but not with white balance. Use the gray card to calibrate the palm of your hand. Once you know the difference in exposure, its easy to meter off your hand and adjust to make it 10% gray reading.

This tip will help very much during Winter when you need to capture fun moments in snow .

Outdoor Photographer Seminar in Denver - tried out the 1Ds MK III

I am currently attending a two day seminar titled "2007 Outdoor and Digital Photo Seminars"
Canon was the official sponsor and there was a stand with their latest gizmos.
I was able to try out the yet to be released 1Ds MK III their flagship model. the 21 MP monster will hit the stores in couple of months.

It had the new canon 14mm L lens on it and the field of view is anything beyond compare.. That is a serious wide angle lens for a full frame camera. The canon had an amazing AF. The weight of the combo was alomst as much as my Rebel Xti+grip +my largest lens(70-200 4 L). Excellent build quality and top notch performance. This one is going to give the medium format serious competition. It has only 5 fps so i dont think its goging to be used by sports photographers like its 1.3x cropped cousin. Main applications would be studio and landscape photography.

Pre Order from Amazon now!!!!

Recommended SLR Camera Gear for the Uncompromising Beginner

So you want to put together an excellent camera kit without spending much money one gear. This is what I would recommend for general purpose shooting.

Camera bodies keep advancing at a very fast pace. What you get today will probably get replaced with a more feature rich model in 18 months. Therefore if you have a strict budget, it is not very advisable  to go for an expansive camera body. However lenses are almost made for ever. A good lens today would be just as useful 10-15 years from now. In my opinion, its better to invest in good glass than a pro body when u start with photography. You can always upgrade you body later and still use the same good lenses on it. I suggest some of the best affordable lenses that you can buy. Two of the three mentioned here are from the Canon's Luxury L series


  • Canon EOS 400D / Rebel XTi

This is the best value for money when SLRs are considered. Plenty of features. The Canon EOS Digital Rebel XTi has a newly designed 10.1 MP Canon CMOS sensor plus a host of new features including a 2.5-inch LCD monitor, the exclusive EOS Integrated Cleaning System featuring a Self Cleaning Sensor and Canon's Picture Style technology, all in a lightweight, ergonomic body. The EOS Digital Rebel XTi is compatible with all Canon lenses in the EF lineup, ranging from ultra-wide angle to super telephoto lenses, and including Canon's EF-S series lenses, manufactured specifically for Canon's APS-C sized digital sensor. An EF-S 18-55mm is included in the EOS Digital Rebel XTi Lens Kit. 1.6x Lens Focal Length Conversion Factor Image Sensor Type - High-Sensitivity, high-resolution, single-plate, CMOS sensor 3 - 2 Aspect Ratio Recording Format - JPEG, RAW, and RAW+JPEG simultaneous recording provided USB 2.0 Hi-Speed Interface, mini-B port, NTSC/PAL for video output Viewfinder Type - Eye-level SLR with pentamirror Shutter Speeds - 1/4000 to 30 seconds Self-timer - 10 seconds delay, 2 seconds delay with C.Fn-7-1 (mirror lockup) Continuous Shooting Speed - Approx. 3 fps (at shutter speed of 1/250 sec. or faster)


  • Canon EF 17-40 f4 L lens

Excellent for Wide Angle, General Purpose and Landscape photography. a bit short for portraits in my view.

    • EF mount; ultra-wide zoom lens
    • Super Ultra-low Dispersion glass; inner focusing; aspherical lens; full-time manual focus
    • 17-40mm focal length
    • f/4 constant maximum aperture
    • Ring-type UltraSonic Motor (USM)


  • Canon EF 50mm f 1.8 
  • Lightweight and affordable, this sharp lens with a fast f/1.8 aperture is an excellent first lens for those who prefer a fixed focal length, and makes an excellent addition to any photographer’s system for available-light shooting. A traditional Gauss-type optical design ensures sharp performance even wide open, and it focuses as close as 18 inches/0.45m.

    A medium telephoto lens with a large aperture brings the subject closer, creates excellent background blur, gives a longer flash range, and affords a faster shutter speed to freeze the action. A standard zoom lens, with its natural angle of view and perspective, captures the subject plainly, with no special effects. However, you can use standard lenses in creative ways by varying the subject distance, aperture, and angle.

  • Great general purpose lens for low light shooting. Also good for portraits. Excellent deal when you consider the price is only 80$.
  • Strongly recommended for most general-purpose photography
  • Designed exclusively for use with Canon SLR cameras


  • Canon EF 70-200 4 L USM

This is Great telephoto lens for a great price. I often use it for outdoor portraits and even for landscapes.  This high performance L-series telephoto zoom lens ensures excellent image quality for every photographic situation and milieu. Filter Diameter - 67mm Lens Construction - 16 elements in 13 groups Minimum Aperture - f/32 Focus Drive - Ultrasonic 76mm x 172mm 705g

      • EF mount; telephoto zoom lens
      • Ultra-low Dispersion glass with Fluorite elements; inner focusing ring; full-time manual focus
      • 70-200mm focal length
      • f/4 constant maximum aperture
      • Ring-type UltraSonic Motor (USM)

Some of the Key Features of this camera are

  • 10.1-megapixel CMOS sensor captures enough detail for photo-quality poster-size prints
  • Large 3.0-inch LCD display with enhanced Live View and broadened color gamut
  • 6.5 frame-per-second continuous shooting capability (for bursts of up to 75 Large/Fine JPEGs or 17 RAW images). Excellent for Sport shooting

The camera has a 5 Star rating and Multiple great reviews at amazon and will be a hot seller for the holiday season.

Buy now from Canon EOS 40D 10.1MP Digital SLR Camera

Detailed Specifications
The most easily visible upgrade on the EOS 40D Digital SLR is the camera's larger 3.0-inch 230,000-pixel LCD screen (compared with the EOS 30D's 2.5-inch monitor). Canon broadened the color gamut, and narrowed the viewing angle from 170 degrees to a still wide 140-degree perspective in all directions. An added advantage of the larger-sized display is the ability to use a larger font size for text, making it easier to read setting and menu options on the screen. The camera's menu is organized in the same tabbed format as the EOS-1D Mark III Digital SLR.

Viewfinder increases optical magnification from 0.90x to 0.95x, expands the viewing angle from 251 degrees to 264 degrees and raises the eye point from 20mm to 22mm.

Camera is made of Magnesium Alloy
The EOS 40D SLR also retains many of the outstanding features of the EOS 30D model, such as its fast 0.15-second initial start-up, its extremely durable shutter (rated up to 100,000 cycles), its top shutter speed of 1/8000 second, and 1/250 maximum X-sync flash shutter speed setting.

Improved Image Quality
Although it is based on the image sensor used in the EOS Digital Rebel XTi, the EOS 40D Digital SLR's 10.1-megapixel CMOS APS-C size image sensor has been significantly improved thanks to the use of larger microlenses over each pixel to reduce noise and expand sensitivity up to ISO 3200. The EOS 40D retains the model 30D camera's 1.6x focal length conversion factor (compared to full-frame digital image sensors or 35mm film) and is compatible with the full line-up of Canon EF lenses as well as the Company's expanding selection of high-quality, affordable EF-S lenses created specifically for Canon digital SLRs with APS-C size image sensors.

Adding to the improved virtuosity of the images captured by the EOS 40D SLR is the camera's 14-bit Analog-to-Digital (A/D) conversion process. Able to recognize 16,384 colors per channel (four times the number of colors recognized by the EOS 30D SLR's 12-bit conversion capability), the EOS 40D camera is able to produce images with finer and more accurate gradations of tones and colors. The EOS 40D also incorporates the optional Highlight Tone Priority and High-ISO Noise Reduction functions first introduced earlier this year with the EOS-1D Mark III Professional Digital SLR.

DIGIC III is the latest generation of Canon's proprietary image processing engine. DIGIC III technology ensures that the fine details and natural colors of the images are optimally recorded and, as an added bonus, is also responsible for the EOS 40D SLR's high-speed performance, faster signal processing, and even its efficient energy consumption.

In addition to retaining the RAW image capture capabilities of its predecessors, the EOS 40D SLR now offers a more manageable "sRAW" recording format. In sRAW mode, the number of pixels is reduced to one-fourth that of a standard RAW image and the file size is cut in half, while retaining all of the flexibility and creative possibilities associated with full-size, conventional RAW images.

Other Hot features:
  • Improved Autofocus and Exposure Control
  • Live View
  • EOS Integrated Cleaning System

Turret Arch - Arches National Park, Utah - Tips for photos and travel

turret Arch

Turret Arch is a very well known geological structure inside the Arches National Park, Utah. Arches National Park contains the world's largest concentration of natural stone arches. Once you are here, you can plan to Hike, Bike, Do rock climbing, horse riding, ATV off-road tours etc. Perhaps even take the Guided tours .Unfortunately I reached there around noon. The flat light will make the pictures dull. If you can reach there for sunset you can really make the pictures pop. Here is a map of the location.

Map of Arches National Park

Tips for getting good photos here

  • The best times to visit and photograph this location is early morning or late evening. The color of the red rocks will be enhanced by the good lighting.
  • Watch for the forecast as it rained the day we went there and we lost much time.
  • Pack your lunch and snacks and get lots of water. Rest rooms and Drinking water are available only in very select locations inside the park.
  • You would need a tripod and a polarizing filter to get good shots
  • If you have a neutral density filter, that would help when the sky is real bright.
  • Try out multiple exposures for HDRs and experiment with Panos
  • Make sure that you don't obstruct other persons view when u shoot

The park has a nominal entrance fee of 10$ per vehicle which is good for 7 days. Make sure that you book your accommodation in advance as The nearby town of MOAB will get filled easily on summer weekends. The downtown has some excellent shops to buy Native Indian art and some good restaurants. Make sure that you grab a copy of the Downtown guide from your hotel. Its is also available in the shops along on the sidewalk. While you are there, please don't forget the Other major parks there like the Canyonlands National Park and Zion

I would Suggest getting one of the following books that would help you understand more about the park and the state

Alpine Tundra Vegetation of Rocky Mountain National Park

Rocky Mountain National Park (RMNP) has a lot vegetation and wild life to offer. However above 11,000 or 11,500 feet ASL, we are above the tree line and all the vegetation will give way to the Tundra. Thats the only kind of plant life that grows in these High Altitudes. The word Tundra itself means "Land of No Trees"

Tundra is subject to extreme weather of freezing temperature, high altitude winds, long periods of snow cover etc. During June to August the Tundra blooms and there is a wide variety of flowers.

Tundra grows at a very slow rate of less than an inch over 20 years. It would take hundreds of years for the Tundra to grow back when damaged. Visitors to the park are required to stay on established trails to avoid damage to the Tundra. However every time I have been to the park, I can see people running around, taking shortcuts, posting for photos etc inside the Tundra vegetation. When you bring children to the park, its your responsibility to educate them on the importance of the delicate environment they are in. What you see in this picture is Tundra vegetation at around 12500 feet ASL. the damage done by walking over them would take several years to heal due to the harsh environment and the slow growth rate of the plant. Damaging the Tundra could cost you a hefty Fine

I am told that there are over 330 variety of Alpine Tundra in the rockies. The best way to have an up close look is to take the Trail Ridge Road inside the RMNP. Please make sure that you educate your group regarding the importance of preserving the Tundra vegetation. Enjoy them from a safe Distance and Dont allow the children to run about on them. Summer time is a good time to visit this place if you want to see the Tundra Bloom. But the season is short and probaly somewhere around June. Please make sure to call the Park authorities and check before planning your trip.

Tips on Low Light Photography - part II

Garden Of Gods, 1805 N 30th Street (at Gateway Rd.)
Colorado Springs, CO 80904

Garden of Gods features some amazing red rock formations in the state. This is a free for all park that offers unpaved hiking paths, interesting challenges for rock climbers, sandstone formations, a wonderful view of Pikes Peak, etc. To make interesting photographs you need to visit this place early before sunrise or during late evenings. This time was my second visit here and i reached there almost around sunset time. The picture above was taken after sunset.

Tech info on the Photo:
Camera: Canon EOS Digital Rebel XTi
Exposure: 0.6 sec (3/5)
Aperture: f/22
Focal Length: 18 mm
ISO Speed: 400
Exposure Bias: 0/3 EV

Here are some more tips to keep in mind while taking photos in low light.

1) I almost always use a tripod. This was already mentioned in the first part of this series but i cant stress this enough. This is the single most important factor in low light shooting.

2) Mirror Lockup. (MLU) . In canon SLR cameras like the rebel series, its available under custom functions. enabling this helps prevent some vibrations caused by the mirror lifting up when shutter is pressed.

3) Remote Cable release This is a very valuable tool. This will help prevent camera shake when u actually press the shutter. Since the switch is connected to the camera using a cable or in some cases Infra Red rays, the shake caused while pressing the shutter button will not transfer over to the camera.

The remote cable release is also very useful for taking Bulb exposures. (Bulb exposures are custom long exposures that is accessible through the manual mode. Basically you can keep the shutter open as long as you want by keeping the shutter button pressed.

More to follow... keep checking

Low Light shooting Tips - Old Abandoned wood house near MOAB,Utah

This picture is featured at Deviant Art

On our way to MOAB Utah, we stopped to fuel and get snacks. It was evening time and I noticed this old wood house by the side of the gas station. Shot with a canon 18-55 USM at 55mm. Color and level adjusted in Adobe Lightroom.

Tips for low light shooting
Shooting under low light can be quite challenging. Tripod is a must to capture all the magic and glow in the sky and the surroundings. This time was able to support my hands on rails near the gas station. This gave me enough support to capture this shot without the need for a tripod. Always remember that when u shoot handled using a non image stabilized lens, you need to make sure that the shutter speed is at least one stop more than the focal length you are shooting at. Please consider the field-of-view multiplication factor (1.6x for APSC Canon, 1.5x for Nikon cropped models) when you calculate the effective focal length. I was short of time here and quickly took this shot. It was framed loosely and finally cropped later in post processing to give a more pleasing layout.
