How does depth of field work... yeh stupid question, but I'm getting rid of my crap "everio" and getting a gl1 before I start my next movie. And yeah I know someone out there is gonna say "dude you should just save up for a gl2"... well that aint gonna happen not with my summer job and I need it soon. gl1's are crazy cheap on ebay and and there from good reliable people. So anyways how does depth of field work?

Wikipedia knows! But if you're looking specifically for the GL1, Google comes up with good articles as well:

The first thing that sticks out (literally) on the GL1, is the Fluorite lens with manual focus ring. The focus button on the left side of the body allows you to switch between automatic and manual focus. The automatic focus worked just fine. It had no problem staying in focus, even as we zoomed in and out at full speed. It also responded well when we panned across the room. The manual focus, which we controlled by turning the fat, sure-grip focus ring was easy to adjust and didn�t drift. Good job Canon.

(A review from this article) Google and Wikipedia are your freinds!

Well, y'know, on most cams thre's a depth o field button and ya jus push that after you focus on yer whatever the film is and i'ts just does the detph of feild on wheatver crap.

Frankly, I'm not quite convinced that you really want to learn about depth of field. Don't even GOOGLE it, son. I want you to go down to your public library, and check out a book on the fundamentals of cameras and lenses.

The library is crazy cheap.

I understand that this community is for everyone - - on every level, but for someone, particularly someone who has "Productions" in their name, well, this person doesn't really care... do you?

Not to be cruel or anything, but having Iggy in your name is no improvement at all next to productions. Now Reborn and I are amateur filmmakers. So whatever the name of his company he wants to have, he can have it, same goes for me. It isn't your companies, so just suck it up and have a little joy for the other people in this community, alright?

Some time ago I wrote the following tutorial:

A Beginner's Guide to Understanding and Using Depth of Field (DOF)

Not sure if the links for further reading are still active. Plus I'm sure there are more 35mm adaptors around these days.

You've got spirit, Reborn... I'll give you points for that.

Fair enough, Seargent.

I'm an amateur filmmaker, as well. I prefer the term "enthusiast", and I'd bet that you're as enthusiastic about films as I am.

My respone to Reborn was ill, and I apologize. There's enough information floating around here, and everyone should know about GOOGLE and the like. The thing that set me off was the fact that Reborn was putting cameras (technology) in place of technique, but still affecting a "yeah whatever" attitude about it.

Again, I apologize to Reborn - - and the FXHome community. This is the most civilized place I know! I'm just in a bad mood...

I was just standing up for some of the other enthusiasts on this site. I have no hard feelings or grudges against you, just helping my friend out is all.

Personally, he is not, in my view, replacing technology with technique. He will use technique, he has got quite a few up his sleeve. He is getting a good camera to get a good quality for the techniques he is using.

I am an enthusiast. All I am doing is taking an old VHS camcorder, but transferring the video to the computer for a good quality and frame rate, seems like a good alternate to spending hundreds of dollars online. I am not saying buying a good camera though is dumb, just to fit peoples budget like mine.

There is no problem being in a bad mood, stressed out, or anything like that. Happens to the best of us, that is just what happens.

Yeah I had a long day at school with 4 final exams and lacrosse and stuff so I'm pretty tired so... well... yeah...

I didn't mean to sound like that... the attitude that I really have for it is "Yeah I want my film to be as good as possible when I get my gl1 so I'm gonna learn about depth of field!" (not being sarcastic) but yeah I should have researched a little more than 30sec on google. Sorry to clog the forum.

I appreciate your understanding, Seargent. Normally, I'm always willing to help, cheerfully - - if it's a subject I'm familar with or have experience in. I'm sorry - - I'm just in a foul mood, for several reasons. I'll just remove myself from this thread, and the site, for a while... At least until I'm in a better "space".

Sorry,
Cheers,
Iggy.

No, no, Reborn... you're fine. That's what this community is all about. I was just being cranky, and you had to get the rotten end. I'm sorry.

Once you get used to and experienced with depth of field, you'll discover that it's a useful element in storytelling!

Just to chime in here-This is the only internet board I have ever seen in which an disagreement ends in a "group hug" rather than a flame war.

Eh? I think you're muddling 'focus' with 'depth of field'. While cameras do indeed usually have an autofocus function/button, depth of field is a different thing that is dictated by the type of lens on the camera.

Most consumer and prosumer cameras come with lenses that are designed for a super-wide depth of field, so almost everything is always in sharp focus. Great for documentaries, not so much for drama purposes.

Good tutorial Hendo - I would just make one observation regarding your statement that 35mm cameras have a small depth of field.

While modern film makers tend towards using long focal length lenses or wider apertures to restrict depth of field it is a choice not a restriction of the technology. Watch any Western from the 1950s and 1960s and you'll see panoramic desert shots pin sharp from here to infinity.

Just watch that. Even if you were more interested in a camera that has the capability of producing DOF (Granted, very minimal), this will explain the basics of DOF.
