The LCD: The Ides of March


The LCD has become the best friend for way too many photographers. Today we are reminded to be aware of those closest to us. It wasn’t good for Julius Caesar — he got stabbed 23 times by his trusted friends on this day in 44 B.C.

Those who rely solely on the LCD most likely will also die a terrible death when they pull these same incredible photos into their computer and enlarge them on their much larger computer screens.

There are a couple of things that the LCD will consistently let you down on and you need to know what they are or you will be burned.

Focus can appear to be sharp in the small LCD on the back of the camera. This is especially true if you never zoom in on the photo to check the image at 100%.

I can tell you from experience that even zooming in on the LCD may not be all that accurate when it comes to the final image.

Camera movement may not show up either on this small LCD.

This is why on major advertising photo shoots they have a computer on location and they pull the images up on the larger screens so the creative and art directors can approve the images.

What are you to do in the field?

Professional photographers have always used some benchmarks to set the camera for camera movement.

First they consider the focal length lens they are using. You should consider your shutter speed depending on the focal length as well. For longer focal lengths, you will probably need faster shutter speeds. Without image stabilization, you are best to use a shutter speed denominator that is larger than the length. So, for 200mm lens, your ideal speed would be 1/250 for a good quality photograph.

Today many people are shooting with long focal length lenses like 500mm and 800mm due to the popularity of those bridge cameras. Bridge cameras are cameras which fill the niche between the single-lens reflex cameras (SLRs) and the point-and-shoot camera.

The other thing affecting the focal length is crop factors due to the size of the smaller sensors.

You may need to be shooting 1/2000 of a building just because of the focal length.

Second you really need to consider the movement of the subject. Athletes in sports are not standing still. My rule is to shoot sports whenever possible at 1/2000.  If you can shoot faster then you will increase the likelihood that the photo is razor sharp.


Do use the histogram on the LCD. It will help you. If it doesn't look sharp on the LCD it will only look worse when you enlarge the image.

Your LCD can help, but realize that you cannot depend on it to give your 100% accuracy. Do zoom in on your images to check for sharpness, but just realize you maybe close but it could be sharper due to camera movement or focus.

Hopefully you are now aware of the LCD being potentially "The Ides of March" for the photographer.

LCD vs Viewfinder: Couple things to consider

Nikon P7000
LCD Benefits

First of all the LCD on most modern digital cameras and even cell phones is pretty big.  Compare that screen to the little eye piece on the Nikon P7000 above and at a first glance you might prefer using it over the viewfinder.

For the most part you can display more information on the LCD than in the viewfinders.  Here you can see I have the camera set for Aperture Priority due to the big "A" in the left-hand corner.  You can also see the ISO of 100, 1/1 and ƒ/4. In addition to these settings you can see the histogram, the flash is turned off, vibration reduction is on and also infrared remote is turned on.

Also you can see the JPEG setting is on FINE JPEG. Next to it the size of the image is set to the highest for this camera, which is 10 Meg.


As you can see in this photo of me using the LCD, I must keep the camera a good distance from my face.

LCD Disadvantages

Holding the camera still this far out is difficult.  I guess you now know why almost all point and shoot cameras now have vibration reduction. It is trying to compensate for the above average camera shake as compared to the viewfinder.


Now using the viewfinder the camera now is right next to my eye.


I can now use my two hands and my head as a tripod. I push the camera next to my head and this will help steady the camera and when you do that your pictures are sharper because you are not as prone to shaking the camera.


My Nikon D4 also has a LCD like the Nikon P7000, but you will rarely see photographers using it to shoot still images.

When you are outside it is very difficult to see the LCD in bright sunlight.  I would prefer the viewfinder.


Viewfinder Advantages


  • Can use your body as a tripod since you can now steady the camera on your head
  • Can see in any situation
  • On most DSLR cameras all the information on the LCD is in the viewfinder
Viewfinder Disadvantages

If you want to take a photo above at a birds-eye l you cannot see what you are doing and the LCD will help you still see what the camera is seeing.  This is also true for low worm's eye perspective.

Conclusion

Neither the viewfinder or LCD works for every situation.  I would always want both on any camera I buy for now on.
