Hi Roz,
I have just caught up on the latest with this thread.
Yes, I do think a monopod may help you, as I use it as a walking stick with my camera attched, over rough terrain, like sand, uneven ground and hills.
I think it would be very suitable for you whole on the fire trail, and see if you can borrow one from someone before buying one.
If you can't I can send you mine, in the mail for you to try.....
I am so excited as I have spent the last three hours outside taking photos, with my new lens, the Canon 180mm macro.....
Yes, I will post some images later, but the clarity and the macnification is just brilliant.....
I was totally amazed by being so far away, just how closae one can get to the subject..... It has amazed me everytinme I looked through the lens. I am goining to LOVE this baby..... |
hey shez .
i can just see you now .. i bet those last three hours went by in minutes ... i'm so happpy for you .. i'm thinking that this new lens has really lifted your spirits .. when you're totally obsessed with photography it really can work in a medicinal way .. !!!
it does for you and it does for me .. i wonder how many other ppl it works like that for .. ??
anyway .. thankyou so much shez for the offer of the monopod to try .. i might just take you up on that .. i think we should say that i can borrow the monopod only if i come up and visit .. that'll get me moving .. !!!
anyway .. i'm looking forward to seeing the photographs from your new lens .. ... :):)xx

firstly i find that explanation a bit confusing .. basically are they saying, in a complicated way, that the shutter speed depends on your aperture setting ?? ..
i have very little knowledge about flash photography .. i've set the intensity of the inboard flash on my 400D so that it isnt too bright, and i'm not even sure i've done it right ..
but i thought that all flash photography was at 1/60 sec .. like when the flash goes off and the shutter at the same time, it only needs 1/60 second .. like a window of time when the flash is firing ..
when i write that i'm thinking of some extremely fast moving objects like a bird's wing moving in flight, and how would you capture that if your shutter speed was only 1/60 sec .. ??
this might be a difficult one to explain .. |
Let's see if I can explain it w/o confusing you or myself :-)
Basically what they are saying is correct, but shutter speed has nothing to do with flash exposure, but rather how much ambient light is allowed to fill the scene.
Keep in mind that your shutter speed will be limited to your camera's sync speed. 1/200 on the Rebel Series. On older cameras, it was 1/60th.
Now, remember two things about flash photography:
Aperture = flash exposure AND shutter speed = ambient exposure
You can slow your shutter speed to allow more of the natural light to fill the scene or you can speed it up to exclude natural light (darkening the background and such). In Av mode the camera will try to determine the best balance itself. In manual mode, you have that control.
Because flash is only on for a very short time, it's exposure is controlled by aperture settings. The more open the aperture, the more intense the flash exposure.
It kinda seems odd when reading about it, but trust me, it's not terribly difficult once you start using it.
Basically if your background is too bright, speed up the shutter, if too dark, slow the shutter down.
If the subject is too bright, close the aperture some, if it's too dark, open up the aperture.

thanks heaps leroy for the generosity with your time ..
i've read it thru ... it's very valuable information .. i'm having a bit'v trouble grasping some of the concepts right this minute, but judging from the level of my confusion its just a matter of time till that light globe comes on .. i'll give it the attention it deserves probably tomorrow .. in fact i'm going to print it out ..
i'm too tired right now to concentrate ...:):)

Imagine shooting with your flash at full power in a manual mode in a totally dark room:
The flash has a constant brightness value (it's VERY bright) and a constant duration (it's VERY short), and you control the exposure by changing the aperture; a larger aperture gives a brighter exposure.
Now imagine shooting in manual mode in a sunlit scene with a specific aperture dialed in: to control the exposure, you change the shutter speed, with a faster speed giving a darker exposure.
Now combine the two with flash used in conjunction with ambient light: you control the flash exposure with aperture and the ambient exposure with shutter speed.
make more sense now?
R.

for extreme close ups you can use bellows and rack and pinion focusing. Also if you want extreme cloe ups you can buy the connectors to microscopes as well.
