A stop is a shift + or - with the iso, the shutter or the f stop. The shutter speeds increase or decrease by twice as fast or twice as slow at each stop. EG, 1 second, 1/2 a second, 1/4, 1/8, 1/16, 1/30, 1/60, 1/125, 1/250 ect

F stops control the aperture the numbers don't really make much sense but the bigger the hole the smaller the number. So f 4, f 5.6, f 8, f 11, f 16, f 22.

Most shutters and f stops can be shifted + or - by a 1/3rd of a stop too.

Iso controls 'film speed' the lower the number the less sensitive to light, the higher the number the more sensitive to light but at the expense of resolution.

Not sure exactly how you selected different iso settings on your camera Tom but try holding the iso button down and clicking one of the dials on the camera.

All these things can be a bit confusing at first! They all control the EV (exposure value) So say you have iso 100, 1/125 @ f 5.6 by selecting iso 200 you have moved the exposure - 1 stop. The same if you move the shutter to 1/250 or the f stop to f 8. So to stop an under exposure when you select iso 200 choose 1/60 or f 4.
Have a play with the camera and look at the results of different exposures.

Just been playing around a bit today on macro mode again, slowly getting the hang of manual focus and depth of field now I think. One thing I noticed is that for most macro shots it wouldnt focus properly no matter how I tried to set it up, is this just because the lens isnt suited for macro shots? Anyway these were the only two that really came out ok.

I like that bridge. Photos are looking good, keep it up! Practice makes perfect.

Also check out the Camerapedia, the glossary is really good, also the articles on the different camera models are a big help. And interesting too.

Cheers Mark looks like a good site. Just got this using macro mode, for some reason when I have it on fully manual it always gives me a really long shutter speed which makes the images blurry, washed out and sometimes just white  :? Any ideas? Its obviously user error somewhere down the line :P

Long shutter speed usually means there isn't enough light getting to the sensor, so it needs longer to develop the image. Try more light, a larger aperture (smaller number remember) or see if you can adjust the shutter speed.

I dont even know how to adjust the aperture and shutter speed, or if I am allready adjusting it I dont know what it is I'm adjusting :lol: Guess I should try and find the manual if she still has it..

Sometimes the aperture controls are on the lens. Y'know where you focus? Have a feel around for something to twist, it will lock into the different positions. should also have stuff marked on it. See the picture, taken with a horrible phone camera. The numbers close to the body are focus, the 50mm stuff is for aperture size.

Ahh I see. No my lens doesnt seem to have that on it. Anyway took the camera into my garden and had a go at doing it all manually, didnt seem quite so bad once I got to grips with it, uploaded the ones that came out best here http://www.flickr.com/photos/22023945@N06/sets/72157603512458764/

My favourite is this one



An improvement?

Tom those pictures are terrific!

I particularly like the 'Church Spire mist' picture. It creates a feeling of subtle detachment and isolation for me.

Either that or I've been listening to too much Joy Division lately ...  :)

Seriously though, very nice stuff.

The camera doesnt really make alot of difference, they are fairly comparable nowadays, at least the digi ones.

I have been taking pictures for so long i cant even remember it, i now do occasional snapshots with a digi camera, which hasnt got alot to do with photography. Like with playing a guitar the effort is in learning to express yourself. Photography is a multitude of media, digital but also film, like when playing trough PC versus playing trough a tube amp.

If your serious about learning about photography i can give you a couple of tips.

Read about photography a bit so you know the basic features and their effects, try to play with those, take pictures at MANUAL setting, dont let the camera do anything for you. But also try to make mental notes what you did and learn from those. Dont delete everything that seems to be less then another picture you took but study it all.

The usefull thing about digi cameras is that you can try endlessly without the hassle and cost coming with using film. Ive spend soooooo many hours in a darkroom i really felt cheated when all this digital stuff came on the market.

When practicing to focus it is usefull to have a film camera around, their viewsceens are much brighter. Especially for portraits playing with focus is essential, you can make or break a good portrait with a good feeling for focus. Do not shoot portaits from hand at first, but take your time.

For dramatic environment shots try converting in black and white and add film grain like Kodak Tri-X, or just use that in a film camera offcourse. If you want to go that extra mile, develop it yourself in rodinal, its just such a spectacular look youll love it.

Ok, that will keep you busy some time, photography is a very rewarding hobby to me, i have captured so much important and interesting moments in my life.

Good luck, Henk

Thanks for that Henk, big post but some usefull stuff there :)

I've stopped using auto mode now, manual feels so much more rewarding when you manage to get a good/ok shot.

For years I had a totally manual SLR camera and learned the relationships between the aperture ( and the effect upon depth of field), film speed and shutter speed although I used to keep an ancient Russian light meter to hand for those awkward moments.It stood me in good stead and I used the knowledge in latter days to manipulate my digital cameras when those around are stuck on auto. Johnny's advice is bloody good and I would just say to look at the composition and think about that before you press the shutter. Having said that, with digital cameras you have far more flexibility to be creative back in the studio.

Is it just something I'll pick up through experience or should I read up on what the various adjustments will do to my photos?

I still dont really know what I'm adjusting on the camera, all I know is that the light meter is centred and I have the objects I want in focus in focus :lol: Will have a look for the manual later so I can see what I'm actually doing.
