Pardon my newbieness, but what is ISO? I have a point-and-shoot digital camera, nothing special. It's set on Auto ISO. I vaguely remember my sister explaining something about ISO and its relationship to grainy images. Help?

No need to pardon! I’m thrilled we’ve got such a neat range on here all connected by one interest. 

It’s a good question, especially considering with digital, it’s easy to wonder why it’s necessary.

ISO relates to the film’s speed and sensitivity to light. Even now with digital, it has been translated into a technical sensitivity equalling that of film. The higher the number, the less light is needed to obtain the correct exposure. 

The higher the number, however, brings out the issue of grain, also known as noise, where your sister is bang on. These are tiny flecks in your image usually most apparent when you blow it up beyond a 5x7, and result in a loss of detail and overall image sharpness.

For a point-and-shoot (PAS), I would say you’re fine leaving it on Auto ISO; I leave my PAS on auto. I’m not sure what model you have, and whether you can change the ISO value, but check your manual and there’s never any harm in playing around. 

I tend to stick hard and fast to ISO values of 100 for outside/bright, 200 for outside/shade, 400 for indoor/bright and 800 for indoor/dark. But even then, I try and make sure the available light does the work, and not just the ISO. 

Hope that helps answers your question, and thanks for asking! 

Comparison: Manual + Program

Howdy! A few comparisons from this afternoon of manual (first two) vs. program mode (last two). All photos are straight out of the camera with no post-processing.

These are meant to show:

  • how two different equations can equal similar exposure
  • how to use EXIF data (the recipe, if you will, your camera stores with the image on how it was taken) to your future advantage for determining manual settings
  • how adorable my daughter is when she’s trying to kiss her teddy bear

Manual (M) > 1/125 at f/2.8, ISO 400

Manual (M) > 1/125 at f/2.8, ISO 400

Program (P) > 1/60 at f/4, ISO 400

Program (P) > 1/60 at f/4, ISO 400

Week Two: Program Mode

(Took this in P mode yesterday, but yes, it has been post-processed. The photos below are straight out of the camera. The rest can be seen here.)

Turning off auto can be a harrowing experience when you’ve just picked up a new camera. It really doesn’t have to be, and the best way to learn is to practice until you’re just shy of blisters. Or the school calls and somebody needs picked up to get out of a test.

This week we’re going to hang out in the Program mode of our cameras. There are three (to five) program modes, depending on your model with the most popular being P, Tv and Av on your dials.

  • P = Program
  • Tv = Shutter Priority
  • Av = Aperture Priority

We’re going to hold our horses and really get to know the first two, P and Tv, leaving aperture for its very own week. Trust me. The lil’ Av deserves it.

Simply put, automatic mode is when the camera makes all the decisions regarding exposure, including flash. In program mode, the camera remains chief on primary decisions but defers to you on the use of flash, ISO and white balance.

Program mode is my favourite of the automatics; I find it easier to get a dreamy look like here:

The flash on your camera will never engage automatically in P mode. Instead, you’ll have to search out available light and keep a steady hand unless you pop it up yourself using the little lightning button on the front/side of your camera body. Let’s try. Twist that body ‘round. Find it? See it? If your dial is set to P, pushing that button should make the flash pop up.

The best way you can avoid needing a flash is by changing your ISO. Outdoors, consider yourself fine anywhere from 100 - 200. Indoors with lots of natural light, I tend to enjoy 400 but it’s a personal thing. If you’ve got limited light indoors, you’re going to need 800 and as the light shrinks from there, the number rises.

Keep in mind, however,  the higher the ISO, the higher the chance of noise. No, not the noise from the cheers of self-victory for mastering P mode, but rather little fuzzy specks that are apparent when you download to your computer or worse, invest in that 20x40 stretched gallery canvas. There are post-production tricks to reduce or minimize this pesky problem, however, but the best way is to prevent it altogether. Always make sure you’re maximizing the light available without altering the mood of the shot (a quiet picture of Timmy and Daddy before bedtime will definitely be ruined by every overhead light beaming in their face!)

Speaking of light, the lower the light and the non-use of flash will increase the chance of blur. A tripod isn’t necessary every time but consider a makeshift one while you quickly frame the shot. Stack the camera steadily on some books or the coffee table, or put your feet shoulder’s distance apart to create a steady stance.

Finally, white balance. If you’re shooting in JPG, adjusting your white balance can go a long way to alter the tone of your shot. Auto is a reliable default, but feel free to explore with others such as cloudy or sunny or shade. White balance finds the middle grey tone to your photo so the camera knows to correctly expose all the other colours. It can be the difference of looking like you’re standing under a rainy bus shelter when, really, you’re field-side for your nephew’s soccer team in the middle of sunny July. Creatively, this can be liberating and it’s a matter of personal preference and one that needs experimented with.

Here, the white balance was on ‘sunny’ but could have done to be switched to ‘tungsten’ or even ‘auto’ to minimize the warm glow and make it seem less artificial.

Shutter priority mode (Tv) lets you determine the shutter speed and the camera match the appropriate aperture for the best exposure. Controlling the shutter speed is ideal for freezing action (a high shutter speed) or blurring for effect (a low one as a car zooms by).

You’re going to need to check your manuals on this ones, folks. Every camera body is different in their ways to switch ISO, white balance, etc. But once you’ve doubled checked that, experiment away!

Week One Rounder: Auto

A retrospective on auto. There were tears on the inside this week. Tears on the inside. 

I knew it was a given that auto would not be my bessie mate, but I had forgotten about how frustrating its most natural features are. There are times, yes, when auto works wonders. And times when it absolutely deserves to be on the business end of a noogie. Let’s explore. 

Auto is good for impromptu snaps in a well-lit area. (Canon PowerShot SD750)

Auto is bad for impromptu selfies in a badly lit area. See the red eye and mishmashed exposure? Mind, that mishmash of light is due to my thumb encroaching on the flash area. Either way, it’s a hot mess up there. (Canon PowerShot SD750)

Auto is good for quick snaps while out and about. When someone just looks so sweet you think there’s gotta be a magic potion somewhere to freeze this ti… Sorry. I digress. Ahem, good example of auto. Note that the composition helps make this picture, not just the technical make-up. (Canon PowerShot SD750)

I brought the point-and-click out of the diaper bag long enough to play inside the house. With the flash on, you get dark, centralized exposure with a certain guarantee of red-eye. The camera is three years+ old now and I forgot a few features… I read the manual to remind myself how to disengage the flash and voila! No red eye, but now we’ve got blur. (Canon PowerShot SD750)

But, if I steady myself and wait for just the right moment, not to mention make sure the battery is completely charged and at its fastest… it can work. Technically, the one above this frantic shot is just a bit fuzzy on the eyes, and not unrecognizable. (Canon PowerShot SD750)

Switching to the big camera, Canon 7D, clicking over to automatic was a first since I’ve upgraded from the 20D. The flash instantly engaged in my living room and gave me this. (EXIF: 1/60 at f/5, ISO 400, 17mm focal length)

I needed to get back to basics, and I needed to make dinner. The next day, I opened every curtain, turned on all four (don’t worry, energy efficient) lights and even the range lamp above the stove. The flash didn’t engage once with all its newly found light and I was able to get Isla like this, above. (Canon 7D. EXIF: 1/80 at f/2.8, ISO 320, 42 mm focal length)

And like this. Still a bit blurry from movement but getting there. Can we tell she’s teething? (Canon 7D. EXIF: 1/40 at f/2.8, ISO 160, 23 mm focal length)

Similar. Notice the lamp is turned on and the natural light from the windows is adding to the scope of bright. (Canon 7D. EXIF: 1/40 at f/2.8, ISO 160, 17 mm focal length)

And one more. My favourite shot, the aerial. She looks little still. And so relaxed, all chillin’ with her arm on her toy. She was very still at this point as the PVR switched on, and she was watching all the red lights on the screen. That’s how I managed to get (Canon 7D. EXIF: 1/30 at f/2.8, ISO 100, 17 mm focal length) with little to no blur. 

In the end? Auto bites the big one but can be manipulated successfully if you’re willing to experiment. It does wonders for quick shots in an area flooded with light and lots of activity. It’s also great for learning EXIF data (the technical data each camera records to an image), seeing what you like, what you don’t and applying it into your manual practice for a DSLR. 

Because, even though she's adorable, nobody needs 700 photos of Sally on a swing!
