Digital vs Film


 

 

 

First ... dispelling a myth (since some people are so uptight over this)

I hope the following isn't too "preachy" but the subject has lately become rather annoying. This is just a preface to the main topic which is actually a lot shorter.

You will find endless whining and complaints that digital cameras are too complicated, not just from "newbies" to digital photography but from some pros as well. Visit just about any photo forum or Ken Rockwell's site to find examples. They say that in the old days you simply ...

  • Popped in a film

  • Set shutter speed and aperture (or shutter/aperture priority with auto-exposure) and ...

  • Clicked for ... perfect results (which was all too frequently not my experience).

How pure. How simple. 

You can do that with digital too. It's called RAW format. You can mimic the simplicity of RAW with TIFF and JPEG as well simply by turning off all the imaging options but that requires a few seconds of effort and some intelligence (although once done you can forget about it). With RAW you don't have to bother even with that because imaging options are automatically ignored. So ...

  • Pop in a memory card (it's probably in there already).

  • Set shutter speed and aperture (or shutter/aperture priority in auto-exposure which is exactly the same process as with a film camera),

  • Then click.

Now, isn't that just like film? What am I overlooking?

I never use the menus on my D300. If they were to disappear tomorrow I would  probably never notice. The manual has 400 pages and I have read maybe 20 of them. There might be a bit of preliminary setup required which is a no-brainer. You could choose an ISO setting (you had to do that with film too) and maybe a preferred metering mode, none of which differs from film camera setup. Leave everything else alone. You are back in the 1970's Happy Days of simple photography with one big exception - better results.

People are confusing choice with necessity. Digital offers the choice of doing in the camera (or in post-processing) what used to be done in the darkroom or film lab. Why do the critics think they have to master all of this? Some of it is doubtless very useful to many photographers but if you find it confusing, ignore it because you obviously do not need it.  The sort of photogs who have a real use for the bells and whistles will know who they are and will figure it out. Ignore them too.

You say you want JPEGs  so you can post to the Internet? Well, with film the lab will do the JPEG conversion for you but you will have to wait.  With digital, you can just use the JPEGs from the camera.  If you shoot RAW, the camera automatically creates companion JPEGs for the RAWs - whether you want them or not. Keep them or ignore them. It's up to you. Furthermore, it is trivially simple to set up a batch conversion of RAW to JPEG with whatever optional processing you want added (let's say auto white-balance) using Adobe, Paintshop or dozens of other great imaging packages. Anyone can do it. RAW is automatically handled. A couple of keyboard clicks and you are done. No waiting for the lab. No sitting in front of the computer for hours as some might have you believe.

What about advanced image processing? If you never had your own darkroom why are you worried about this now? With film, image processing was never even possible unless you had your own darkroom. You just accepted what you got including poor white balance, over/under exposure etc. Digital gives you the choice of fixing things in the camera or once they are in your computer. No one is forcing you, however, and if you want results "as is" it is just as easy as with film when you shoot RAW. Why is this so difficult to get across?

What about flash? I challenge anyone to demonstrate that flash is easier to use on an old film camera. Snap an SB-800 onto the D300 and both units instantly talk to each other, sharing shutter speed, aperture, ISO, subject range etc. You don't have to do a thing. Anyone with an IQ of 37 or more can use the system. If you want things simple and fool-proof, ignore the flash menu. Just relax and take great pictures.

Digital is much faster and easier to use than film. I wish I had  a dollar for every time a great photo opportunity emerged and - oops! - out of film. Now spend 5 minutes putting in a new roll while Elvis melts into the crowd. You must first peel off a stiff, metallic wrapper, then find a place to put it where an environmentalist won't get upset. Then the sprocket holes aren't lined up right and you have to start all over, having botched the first two frames. Better remember to rewind before opening the camera or you ruin everything. With a big flash card you can shoot for days and even putting in a new one takes only seconds.

Why buy an expensive digi like the D300 if you aren't going to use all the options?

  • Build quality - long-term durability. The notion that camera bodies quickly become obsolete is complete nonsense. The D300 takes fantastic pictures today and will be doing so a decade from now. Why wouldn't it?

  • High pixel density low noise sensor. Yes, this is a remarkably good landscape camera.

Options aren't what raise the price of a digital camera. It's build and sensor.

My main beefs with digital (just to concede the critics do have a few good points):

  • The cameras and lenses are way too heavy but that's not a criticism specific to digi. Electronic film cameras are too heavy as well. The problem has to do with automation, not digital.

  • Won't work in freezing temperatures (but ditto for electric film cameras).

  • Too many RAW formats. Not enough standardization, although we hear it's coming.

  • Dirt on the sensor. It's a constant hazard. You can have blobs and specks straight out of the box. Once cleaned, my DSLRs have stayed that way. I am very careful - and lucky. With film, you get a clean, pristine "sensor" every time you advance a frame.

The manufacturers could be very helpful with this complexity issue if they documented their products differently. The first part of the manual should describe straightforward traditional photographic technique as if introducing an old film camera. This would take just a few pages and get everyone off to a comfortable start.

It is just human nature but people are attracted to novelty ... "features" and gimmicks. This sells cameras more than substance. Then we get the thing and can't figure out how to use all that crap we don't really want or need anyway. If we feel cheated and frustrated we have only ourselves to blame. 

That's it. On with the main subject ...


 

So why use digital? 

Because if you are still using 35mm film you might be missing out on finer images - but there are other reasons.

  • Good film and film cameras are increasingly difficult to find, at least around here. Film is a technology in retreat and major manufacturers are discontinuing production of materials and equipment. Some cut film has disappeared entirely. Sure, there's still Velvia and a few other great films but its a long drive across town to find it and a week or more to get it processed. You used to find a choice of good films at any drugstore. Quality commercial processing for color film is also becoming scarce. These days its not unusual for a roll to come back with images fogged from using exhausted chemicals. Scratches are not uncommon. When you complain, the store says the problem is with your camera.

  • With the better equipment such as DSLRs (digital Single Lens Reflex) from Nikon and Canon, digital exceeds 35mm color film image quality at any print size. In some circumstances (such as poor light or low contrast), it is no contest at all. Good digital images routinely demonstrate a clarity and depth I seldom see in film images.

  • In the "snapshooter" range many shirt-pocket size digi units deliver better performance than what we were forced to endure with compact, point-and-shoot 35mm equipment of the sort that began flooding the camera stores in the 1980's.

  • The capability for immediate image review encourages experimentation and feedback. Digital can make you a better photographer. This may be the single most important advantage of digital. Instant feedback is recognized as a key factor in support of the creative process. The painter sees the result the moment his brush touches canvas, the musician hears a note as soon as he plays it and the novelist sees the words as he types them. In each case there is an immediate possibility the result will stimulate a new direction in the effort.  Pity, then, the poor film photographer who, alone amongst artists, must wait a week or two to find out if he got anything right at all or, indeed, anything. Film gets in the way of creativity.

  • Digital produces more pleasing results in poor or flat lighting with more shadow detail and superior color rendition.

  • For similar sensitivities (ISO rating) a DSLR will exhibit less noise (that's "grain", in film).

  • Variable ISO settings and image properties settings available on many digital cameras offer a frame-by-frame flexibility in creative control that with film can be obtained only by physically exchanging rolls of film - totally impractical with 35 mm - or by using a bulky cut film camera.

Note that the foregoing material begins with a qualifier: "35 mm film". While digital at its best is a match (or more) for the best 35 mm film image quality, neither 35 mm nor digital can provide anything like the presentation resolution of medium and larger film formats such as 6 X 7 cm, 4 X 5 etc. at very large sizes (larger than A3 or 13 X 19).
