Hi all,

I had a fun weekend roaming around Oxfordshire and i took a few shots.
I've got a few questions that i came up against while i was using my camera (canon 450d):

- when shooting i sometimes find i cant get the right setting to capture the right amount of light and still keep the detail in the clouds.
  i played with the av and tv modes to try and get it right but i didn't really manage to get it how i wanted. i often found that i either got the detail in the foreground     but the clouds were bleached out or the clouds looked good and the foreground was too dark.

- without using the no flash mode how can i turn off the flash? it was quite annoying taking a photo during the day and having the flash pop up all the time.

- im probably being stupid but how do i turn on the live view screen? ive gone into the settings and set the live mode on but it still doesn't work?

- what mode do you guys normally shoot in? are there any particular settings you use as standard?

thanks smile

Digital cameras don't have enough dynamic range to be able to capture the full range of exposure levels between the ground and a bright sky. To combat it, you can use a graduated neutral density filter to darken the sky, or combine several different exposures in photoshop, or use HDR.

Don't use the auto modes. There's not much point in having an SLR if you let the camera decide everything for you IMO. Use aperture priority, shutter priority, or manual depending on what you want to achieve.

It may be different for yours, but after enabling it in the settings you activate it by pressing the set button on a 40D.

Aperture priority mostly. Occasionally shutter priority and manual. Program mode when the dial gets knocked and I don't notice.

Welcome to the world of exposure latitude. Basically if the exposure for the sky is over two stops higher than for that of the land there's not really much you can do in camera in regards to changing settings depending on exactly how big a difference there is. Things you can try are:

Set your camera to Evaluative metering mode which splits the frame into something like 35 zones and works out the average exposure for them all.
When you take your meter reading make sure you DON'T meter from the brightest or darkest parts of the frame as this will either make the highlights be over exposed or the low lights under exposed. Instead you want to look for something that has the reflective quality of 18% gray as all cameras light meters are calibrated for 18% gray - This is why if you take a photo in the snow the snow often looks more gray than white.

If the conditions cannot be controlled by these methods than basically the scene is beyond the exposure latitude that your sensor can handle. The only things you can now do are:

Use graduated neutral density filters. These come in different strengths and are basically a square piece of glass which is gray at the top and clear at the bottom. The idea is that you put the gray bit over the sky and the clear bit over the land and this evens out the exposure latitude reducing the brightness of the sky.

The other thing you can do is to, ideally, use a tripod and fire off 3 or more shots at different exposures and i.e. -1, 0, +1 and then merge them in Photoshop. You can also sometimes get away with shooting the one shot in RAW, processing it in 3 or more different exposures and then merging them in Photoshop. Incidentally this is also the method used for creating HDR shots for which you would require other software.

- without using the no flash mode how can i turn off the flash? it was quite annoying taking a photo during the day and having the flash pop up all the time.
I'm guessing that you must have been using one of the scene modes? Flash will only pop up when you are using settings that mean that the image will be underexposed using the settings you've chosen. When you use one of the scene modes you are basically letting the camera decide all the settings for you. So, use either AV, TV, Program or Manual modes and adjust your ISO accordingly, if the flash pops up, increase the ISO or use a larger apperture (smaller number) or a longer shutter speed.

No idea, my camera doesnt have this feature

- what mode do you guys normally shoot in? are there any particular settings you use as standard?
Almost exclusively I use Aperture Priority (AV). This is because the most important aspect for me is the aperture as this controls depth of field. I can therefore set the aperture that I want to use but the camera will then work out the correct shutter speed to use with that. If I look through the viewfinder and see that the shutter speed is too low I simply increase the ISO until I get a shutter speed I like.

thanks for the advice much appreciated it has been good learning how to use the camera and i obviously have a lot to learn.

i will look into the cost of buying a filter. how do i set my camera to use the "Evaluative metering mode". what i have been doing is playing with the curves in photoshop to get teh clouds how i want them so that might just be something i have tog et used to doing for these types of shots.

i was using some of the auto modes as i sometimes didn't have the time or the knowledge to set up the camera quickly. hopefully this will come in time smile
i generally use the av mode to get the right amount of light and depth and occasionally use the tv mode. ive not been brave enough to use the manual mode yet  Tongue

what i have been trying out is different setting for the same shot to see the difference so i can hopefully understand it a bit more. i do need to test out teh iso setting more to see the results.

ive also been trying to get my composition correct or at least think about it more. what i am finding is that the viewfinder doesn't show the full area im shooting how do you get around this? is there a rule to this so i can position things better?

i will definitely be looking to get a tripod like a gorillapod to begin with. i was having to rest my camera on fences or oposts to take some of the slower shots.

dave - thanks i managed to get the liveview working now i didn't know i had to press the set button while i was shooting.

The viewfinder only shows 95% of what the censor does, so keep that in mind when composing you picture.

I'm not sure on the 450D where the meter setting are, on the 40D there's a dedicated button on the top next to the LCD. I think yours will be via the menu system. Look for the symbol that looks like an eye in a box.



As for filters, you don't need to go there just yet, to get good ones will cost lots. For now stick with taking two exposures, one for sky and one for ground and blend them in photoshop.

EDIT: ohh and if you get a tripod, get the best you can afford, good ones will last a life time. Gorilla pods are brilliant but are no substitute for solid tripod

Once you've enabled live view in the menu, i think it is the 'set' button to turn it on.

HDR is a great way of getting the clouds to jump out, but you will need a steady hand or a good tripod to get a set of bracketted shots.

Following the tripod advice, i totally agree with getting the best you can afford, i spent more than i wanted on mine, but it is very sturdy, very good and i do use it all the time. As you've just bought a camera i'm guessing you're probably skint now, so you need to decide whether to get a half decent one now or wait and spend the extra. Several guys in work with me have a Manfrotto that is about £50, a good light tripod, mine cost double that but is imo well worth the extra. There is a thread around here somewhere discussing these when me & jee were looking to buy, i'll try dig it up.

edit: can't find it, might be on the old forum, this thread goes into tripods and bags - might be of use to you.

FACT! hehe ye i am a bit skint after buying the camera. im just not sure about lugging a tripod around but i know i need one to get the shots i like taking.

I'd also advise taking a look in the manual that came with it wink

Now where is the fun in that smile

I will have a look at the evaluative mode. ive found it it is actually a button on the back. now i sut need to figure out how to use it .
ok sickpuppy you win ill go and read the manual  biggrin

I bought a tripod bag that i sling on my back when i'm off on a trek, if i'm not using my tripod though i usually put it on the ground whilst i'm taking shots.

hmmm might be a good idea now im not sure if i should get a gorillpod to begin with and then get a larger tripod or if i shouold just get a biggr one now. what i like about the gorillapod is its size and ease of use to get it out if i'm out and about. it should be good for lower tings as well like flowers.

Gorilla pods are great, and the fact that they are small and light is a major selling point, but with what i generally photograph (landscape/seascape and night shots) i find my tripod more useful, plus i don't mind lugging round stuff as i sometimes have my macbook with me too - i'm like a bloody pack mule !
