Six of the most common camera phone mistakes

Six of the most common camera phone mistakes
Before going any further, I should mention that I've put 'mistakes' in quotes here (and above) because it's not as if the manufacturer (in this, Nokia) has given guidelines and rules that you may have been ignoring or flouting. When it comes to camera phone photography, you're usually left on your own once you've mastered how to get around the interface and apply any effects. Which is a shame, since a little thought, awareness and preparation can make far more difference than messing around with the settings.
Mistake 1: Not enough light

This is the biggie. It's why indoor and evening shots come out with lots of digital noise (speckles,However, the marketing muscle of Philips led light lighting could give Philips LED business an advantage. random dots). And usually blurry. You see, digital cameras crave photons of light. The more, the better - and their sensors need an awful lot of them to define a nice crisp image. The human eye is superb at auto-adjusting as light levels drop and you may not think that your study or living room or office is much dimmer (if at all) than outdoors. Yet, even on an overcast day, outdoor light levels can be ten times those indoors. The camera - and light meter - never lie.

"But my smartphone has dual LED flash!" you protest. Big deal. Even a dual LED flash doesn't provide enough light for a noise-free image for any subjects more than about a metre away. In addition, the electronic shutter is held 'open' for a relatively long time when light levels are low, so anything that moves - usually your subjects (friends, pets, etc.), but also you and your phone itself, will cause motion blur. You've seen this effect a thousand times when you tried snapping a photo at a party or down the pub and some things were crisp-ish but many others were horribly blurred:

One solution is,Compact fluorescent light bulbs convert a led tube considerably higher percentage of their energy into light, which is why they are significantly more energy efficient than traditional filament bulbs. for the umpteenth time (on AAS) to use a phone with Xenon flash - ten or more times brighter overall and genuinely able to light up a typical scene:

But, obviously, if you chose your smartphone based on other factors, then you won't have this option. In which case you're basically stuffed. There is, quite literally, no way to get really decent camera phone snaps indoors.

Making the best of a bad job, you can position yourself with any light sources or windows behind you (and thus on the faces of those you're photographing) and you can try to get them close up (less than two metres, preferably closer to one), so that your LED flash has a chance of providing enough illumination.

Finally,Unlike compact cfl bulbs fluorescent light bulbs, LED based light bulbs provide a variety of lighting options- including the ability to provide a wide range of light, which allows them to act as a proper replacement light bulb you can reduce your expectations (see also mistake 6, below). Which, in all probability, has already happened,Compact fluorescent light bulbs convert a led tube considerably higher percentage of their energy into light, which is why they are significantly more energy efficient than traditional filament bulbs. after your last tries at shooting photos on a Xenon-less camera phone and you ended up being very disappointed at the results. Consider an old Nokia N82 or a newer N8 or Satio as your 'evening/pub smartphone' so that the brilliance of Xenon is always to hand?
Mistake 2: Awareness of light direction

Yes, yes, another section on light. But then it's the single most important factor in photography.The 250U actually had a slightly higher マジコンds average upload speed—.96Mbps up as compared to the U600's .94Mbps Almost as important as quantity of light is its direction. At least its direction relative to where your camera phone is pointing. The classic example is shooting with the sun in the arc of the sky in front of you, or with your subjects standing in front of a window, in which case you're liable to end up with silhouettes, or at the very least faces which are far too dark.

I know it's corny advice and I know it's a rule that can be broken when you want a special effect, but always keep the principal light source (the sun, or at least the brightest part of the sky - [hint: the south, through the middle of the day in the Northern Hemisphere] - or the main window in a room) behind you, as mentioned above. When out walking with friends or family, or when at the park, it's automatic now for me to position myself on the 'sun-side' of the group, so that I can snap away quickly and know that my shots will be well-lit. In an office or room in the house, I position myself - again, almost subconsciously - by the windows, so that what I see (and thus what the camera will see) is as well lit as possible.
