My Experience with the ViewSonic VP2468

The computer monitor market is very competitive. ViewSonic has been making monitors for a very long time, and they understand quality. I used to use the CRT versions back in the day, when they were some of the best monitors on the market. To my delight, ViewSonic has recently introduced another series of high quality monitors to compete in the demanding professional photographic market.

The model I have been using for a while is the VP2468. It is a 24” monitor with full HD 1920 x 1080 resolution, utilizing a white-led backlit, anti-glare SuperClear IPS panel color active matrix TFT LCD. There are many video inputs, including two HDMI 1.4 ports, and two DisplayPort 1.2a ports. The VP2468 has an excellent viewing angle of 178 degrees both horizontally and vertically. It can display 99% of the sRGB color gamut, and it uses a 14-bit/3D look-up table (LUT) for very smooth and accurate color. For those who want to tweak color beyond normal calibration, the VP2468 allows for independent 6-axis color (red, green, blue, cyan, magenta, yellow) hue and saturation adjustments.

When I unpacked the VP2468, there was a piece of paper that had highly-detailed factory color calibration and uniformity report. This is a factory report, done for each monitor individually, that describes the accuracy of the pre-calibration and screen brightness and color consistency. The VP2468 undergoes four times the amount of attention with factory color calibration than competing brands. Although you should still calibrate your monitor for your individual working environment, you can be rest assured that your VP2468 has a tight manufacturing tolerance and will be accurately prepared for you to begin using it in your color managed workflow. To calibrate and profile the VP2468, ViewSonic sells the Colorbration Kit CS-XRi1, but the X-Rite i1Display Pro and i1Pro 2 hardware calibrators will also work.

The ViewSonic frameless design bezel is extremely thin. It’s so thin that the buttons are on the back edge of the monitor. This bezel design will allow for a wonderful multi-monitor setup, as the gap between the screens will be very small. It will take a little time to become familiar with which button controls which setting, but once you’ve got your monitor calibrated and profiled, there’s really no reason to keep playing around with the monitor controls.

Calibrating this monitor was a great experience, and being a fine art photographer and printer, this is critical to maintaining my color workflow. The software used to calibrate the ViewSonic monitors is called Colorbration, which is based on the X-Rite i1Profiler application, with some features made specifically for ViewSonic monitors. Colorbration has basic and advanced modes. In the basic mode, a wizard takes you through all the calibration steps, easily and quickly. Advanced mode provides you with many professional options to fine-tune the calibration to very specific requirements. For most users, especially when getting started with a color managed workflow, the basic mode will be more than sufficient.

To help make the calibration process easy, the VP2468 supports automatic display calibration (ADC). ADC allows the Colorbration software to communicate directly with the monitor and configure all required settings with minimal to no user intervention. The monitor must be plugged into the computer with a USB cable for ADC to work. During the calibration process, there is an option for running the uniformity correction at the end of calibration. The ViewSonic uniformity correction is used to ensure that all areas of the monitor have consistent and accurate brightness and color values required for proper calibration, based on the calibration settings you chose. The VP2468 can be successfully calibrated to low brightness values, something that is usually found on more expensive monitors. One important feature of the VP2468 which is extremely important for accurate and consistent color is the anti-glare screen, as opposed to a glossy screen which is far from ideal for serious photographic editing.

Uniformity of brightness is another advantage offered by color management monitors. Most general-purpose monitors suffer from slight variations in brightness and color across the screen. These differences occur during the manufacturing process at the panel factory and may not be noticeable to the average user. The image processing power user, however, should be able to detect these variations, as they can impact the quality of their final product. This is why monitors that are purpose-build for image processing are tested at the factory to ensure uniformity.

It’s very important to choose the proper monitor for post processing your photos and I’ve been very pleased with the new ViewSonic VP2468! The ViewSonic monitors utilize some of the best display technology, and offer very compelling features and quality for the price. If you’re in the market for a new monitor, you should seriously consider the ViewSonic VP2468. It is a monitor that you can rely on for highly accurate and consistent color, helping you bring your photography to the next level!

Free 1.4x And 2x Teleconverters For Lumix Users!

I had a feeling that title would grab your attention. However, I’m not pulling your leg, I’m being totally serious. If you're saying “But Panasonic doesn't make teleconverters for their Lumix lenses!”, you would be completely right. However, you might be pleasantly surprised to discover that both of the teleconverters are probably already in your bag!

For those who may not be familiar with what a teleconverter is, think of it as a lens extender that turns your lens into a longer lens. The two most common teleconverter strengths are 1.4x and 2x. If you were using a telephoto lens that was 300mm f4, using the 2x you would end up with a 600mm f8. You can see that although your lens is now effectively twice as long, you've also lost two stops of light. Losing two stops (on a 2x) will really slow your shutter speed down, requiring you to raise your ISO higher than you might want. The other not so obvious issue is that the majority of cameras can't focus when f8 becomes the max aperture. In addition, quality teleconverters are not cheap and they take up more weight and bulk in your bag.

For years there has been a feature on many Lumix cameras called “Ex Tele. Conv.” (ETC). The feature is found in the Rec (red camera) tab in the menu. To enable it simply set “Ex Tele. Conv.” to “Teleconv”. The manual isn’t particularly clear and doesn't give this amazing feature enough attention. Therefore, I’ll explain what it is, why you’ll probably want to use it for certain situations and why it’s as close to a free lunch as you’re going to get!

ETC mode is not digital zoom. It is purely optical. Some cameras have a separate digital zoom feature, which I suggest you never use, as the quality is usually horrible at best. The only caveat to ETC mode is that you can't shoot RAW but only JPGs. Although I'm a RAW shooter, you'll soon read why I sometimes shoot JPG!

ETC works by masking the sensor. Think of this as the camera putting a piece of tape on part of the sensor and leaving just the centre exposed. There is no interpolation or image degradation happening. The JPG resolution setting will determine the amount of masking. More masking means a longer effective focal length (larger teleconverter power).  On the GX8, if the JPG resolution is set to Medium (10 megapixels), you'll effectively be using a 1.4x teleconverter. If you set the resolution to Small (5 megapixels), you'll be using a 2x teleconverter. Since you can still use the Fine compression setting, 5 and 10 megapixel images are great for a number of applications. For example, either of these will be more than adequate for anything online and if you print your images, even a high-quality 5 megapixel JPG can easily print to 11x14” or larger (depending on quality of lens, focus, shutter speed, ISO, etc). When I first discovered ETC mode, you could say I was somewhat thrilled that I was able to turn my Lumix/Leica 100-400mm f4-6.3 lens into a 400-1,600mm f4-6.3 lens (2x due to the m4/3 crop and then 2x for the ETC mode) that autofocuses, or the Leica/Lumix 45mm f2.8 macro lens into a 90mm f2.8 and in Small JPG mode provides 2:1 macro magnification!

However, unlike using an external teleconverter the main benefits include:

1)     You won't lose any image quality as you're not adding additional glass.

2)     You don't lose light so your shutter speed can stay the same

3)     Whether you shoot with the medium or small JPG resolution, your max aperture will never change, nor will the weight and bulk in your camera bag!

4)     You can use any lens with Ex Tele mode, from fisheye to super telephoto, which is impossible with an external teleconverter.

A benefit of ETC mode that is identical to an external teleconverter is that the minimum focusing distance of the lens remains the same, which is great as you'll get more magnification from your lenses for closer subjects which can also allow for more working distance.

Some of you may be wondering why not just shoot RAW and crop in post processing. The following is a list of reasons why ETC mode might make more sense:

1)     Your camera is metering for only the area the lens sees, not the whole sensor. This will most likely give you a more accurate meter.

2)     Since you are only focusing on what the lens sees, it'll be easier to focus on your subject.

3)     Your camera buffer won't fill up as fast with continuous shutter since the JPGs are 1/3 to 1/4 smaller than a RAW file.

4)     You'll get significantly more images per memory card. Although memory is cheap these days, getting more images on a card during certain shooting situations might be useful.

5)     Due to the masking, the sensor will only see the middle, or sharpest part of a lens.

6)     You can make-up an extra stop or two to keep your shutter speed faster. For example, let's look at the Leica/Lumix 100-400mm f/4-6.3 lens to achieve a faster shutter speed. Instead of shooting the lens at 400mm f/6.3, you can enable ETC mode, set your JPG resolution to Small (2x teleconverter) and shoot the lens at 200mm f/5.1. You'll now be shooting with a 400mm f/5.1 lens with a shutter speed just under one-stop faster which can make or break a sharp shot in low-light.

7)     You don't need to physically change lenses which saves time and also keeps more dust off of the sensor.

A few tips and tricks include:

1)     You can assign the ETC mode to a custom function button so that it's always quickly accessible.

2)     Considering your lens will now effectively be either 1.4x or 2x longer, you have to treat it as a longer lens and make sure you use appropriate settings (shutter speed, image stabilization, etc).

3)     ETC mode can also be used for video.

So as you can see, ETC is pretty much a free lunch with some amazing dessert. The only tradeoff is that you have to shoot JPGs, which might be fine for some and unacceptable for others. Being a RAW shooter, I'm now shooting 90% RAW and 10% JPG.

 
 

My Lens Choices and How I Use Them

With such a wide range of lenses available for camera systems these days, it can be difficult to choose the ones that work best for you. Too frequently I see questions by new photographers asking which lens is the best choice for landscapes or wildlife, for example. Just as frequently, I see answers to those questions that suggest using a wide angle lens for landscape and a super telephoto lens for wildlife.   

When asked to critique photographs, I often find that the photographers had a great vision of what story they wanted their photo to tell. However, the incorrect lens was often chosen and unfortunately reduced the impact of the final image. For many of the images the photographer used a lens wider than necessary and there was no obvious subject of interest, causing the eye to just wander around the image. It's worth noting that the wider a lens is, the more difficult it can be to create a strong composition.  

Depending on the diversity of your photographic subjects, you may be able to use only one lens. Being a fine art photographer who shoots landscape, wildlife, abandoned places and abstract types of images, I regularly use a wide range of lenses. I am shooting with the Panasonic Lumix camera system and my widest angle lens is 14mm and my longest 800mm (both 35mm equivalent).   

Below is a list of lenses I use and a brief description of how I generally use them. These lenses are very sharp autofocus (except the manual focus Venus 60mm macro) very quickly. I hope that after reading these you may perhaps be inspired to try some of your lenses for other subjects:  

Lumix G Vario 7-14mm f/4 (14-28mm equivalent on 35mm)  

This lens is very wide. It can be difficult making strong compositions with such a wide-angle lens. It is very important to pay attention to foreground, mid and background in your scene. I use this lens almost exclusively for night photography and when I really need toexaggerate foreground objects. This makes a scene seem vast and can create a very impressive dynamic scene.  

Lumix G X Vario 12-35mm f/2.8 (24-70mm equivalent on 35mm)  

For many people this lens is their go-to lens. For me personally it is more of my general purpose lens. It's not wide enough or long enough for a lot of my subject matter. Especially now since the m43 equipment is so light, I'll usually bring it along with all of my other lenses because it is incredibly sharp and is useful in many situations.  

Lumix G X Vario 35-100mm f/2.8 (70-200mm equivalent on 35mm)  

This is definitely one of my go-to lenses. I often use it to exclude elements from a scene to create more of an intimate landscape. It's a great focal range and the lens focuses as close as 1ft????? Which is great for close-up work. The addition of extension tubes can make this lens great for insects and smaller subjects as well. Along with the 100-400mm lens, this is used a lot for my abstract photography. The dual image stabilization support for this lens makes it great for great deal of subjects and lower light shooting.   

Lumix / Leica DG Summilux 15mm f/1.7 (30mm equivalent on 35mm)    

I use this lens for night photography and for macro with extension tubes. The lens is fairly wide-angle with a large aperture so it works well for shots of the night sky. If paired with extension tubes (I use the Kenko brand), it works as a very capable macro setup. Depending on the amount of extension tubes used, you can get more than 1:1 macro. If you add too many tubes you won't be able to focus on your subject as it will literally be touching the front of your lens.  

Lumix / Leica DG Elmarit 45mm f2.8 macro (90mm equivalent on 35mm)  

This is my Panasonic macro lens of choice. It offers greater working distance than the 30mm macro lens and is also a Leica lens. Although this lens also works very well for subjects focused at a distance (not all macro lenses do), I pretty much dedicate it to macro. Fantastic dual image stabilization allows me to shoot macro handheld in a pinch which I would never really have done. However, I will still use a tripod 99% of the time unless photographing moving insects.   

Lumix / Leica DG Vario Elmar 100-400mm f/4 - 6.3 (200-800mm equivalent on 35mm)  

I absolutely love this lens. I not only use it for wildlife but also for situations where I want extremely shallow depth of field or where I can't get close enough to the subject. This lens can focus as close as five feet across the whole zoom range, which is incredible and allows for a lot of close-up opportunities. Since there is also hardly any depth of field at 400mm (800mm equivalent), sometimes I'll focus stack to obtain a bit more depth of field. It is critical to use a good tripod or have the lens slightly weight dampened as a mild breeze is enough to cause camera / lens shake at this magnification. Slower shutter speeds will be more affected by this. Consider using a small beanbag or your hand to help control any vibration. Aside from using it for wildlife, I use it a lot to create abstract images since I can isolate subjects extremely well.   

Venus 60mm f/2.8 (120mm equivalent on 35mm)  

This is a vey sharp specialty macro lens that provides 2:1 magnification without the need for extension tubes. It also focuses to infinity. Unlike my Leica 45mm macro, I only use this lens for macro. It is a completely manual lens with no image stabilization or auto focus and it doesn't relay any information to the camera. This is also the only lens I use a (high quality) UV protective filter on as at macro ranges the lens elements retract into the lens barrel at various magnification levels.
