My Photography
Ok I just did this challenge while sitting here reading this tonight so no fancy pics here. I chucked a few things on the dining room table as I don't have tripod here to stop movement, Also has poor flurescent light aswell but still got the point. The first Pic I took at F4.5. They keys are the focal piont and the only thing in focus. The next F22 and all clear...this second pic took quiet a while to take hence the sitting on the table. I thought i had the ISO set at 100 for both but wouldn't that mean the pics took the same time to take?
I enjoyed the challenge I learnt from it, Thanks!
Woops guess i don't know how to add pics yet

Does anyone know why I would only have two f setting f6.4 and f3.1, as I own a Fujifilm s1800?
According to your manual - page 40 you can set apertures. See page 43 of your manual for more information. If you get stuck ask again here.
Can someone please tell me what I am doing wrong - I have tried numerous times to take photos, of different subjects outside, changing the aperature from f3. to f22 and they are all turning out very dark; yeet when I take the same photo using the automatic option it works beautifully? I have a Nikon D60 with kit lens 18-55mmm.
f22 is a small hole and will give you greater DOF
f4 is a big hole and will give you what is call a Shallower DOF
When I say , Hole thats the size the Aperture blades make at that setting
Usually you use (As an example) f4 for Portraits , So you blur the Background (Shallow) with a nice Bokeh to highlight the subject
Landscapes you go for greater DOF and use (Example) f8 upwards to f22
Hope thats not to confusing - Bill
Thank you for explaining
I think I'm confusing myself with not being able to understand the 'terminology'.
My thinking was that: smaller f stop means a smaller number e.g. f2.8 = a large 'hole' or aperture opening
and larger f stop means a larger number e.g. f22 = a small 'hole' or aperture opening.
So, if I understand your explanation correctly then the term f stop actually describes the size of the 'hole' i.e. aperture opening and not the f number.
Yep , I think you've got it , If you want to highlight a particular subject and take out any other distractions use a smaller f stop number f2.8
If you want the whole scene in Focus , Go to a higher f stop f10 to f22 , eg , Landscapes/Seascapes , Funny I used to go to a beginners photography class and even there , Understanding the f stop was the hardest thing for people to get their heads around - Cheers Bill
Part of the reason (but not the whole reason in this photo) is vignetting. When the aperture is really wide (small f stop) you get darkening around the edges of the pictures (varying depending on the lens and sensor size) called vignetting. This is because when the aperture is small (high f stop) only the light from the centre of the lens makes it through to the sensor. When the aperture is large (low f stop) the light from the whole of the front of the lens is going into the sensor - but the edges of the barrel get in the way a bit and cause shadows (can't think of a better way to describe it). If you stack too many filters and shoot with wide open aperture then the vignetting gets worse, because the edges of the filters are making the shadows worse.
I found the problem. It appears when I changed the aperature reading I also changed the exposure compensation which was making the photos very dark.
Here is the photo taken at f4.5

Here is the photo taken at f29

Apart from some slight changes in DOF, not so clear I really can't see a significant change??

I'm still getting my head around this too, but I think when you use f29 you might find camera shake as the shutter stays open longer to adjust for light so check your exif data to see if shutter speed changed in relations to change in f setting, cause when you change your f your shutter will decide on the best setting.
I have to add I am still learning this but feel that I'm getting there. Can someone with more experience confirm.
Nikon D90, Nikkor 50mm, Nikon 18 - 105mm
What I noticed about this was that sometimes the camera would go higher than 22 or not as low as 3.5 depending on the image or lighting. At first I was playing with the exposure compensation but then I realised and set that to 0 again. With the 22 shot I cant see any bird in complete focus but all are way more defined in this. Using the 4.5(the camera wouldnt go to 3.5 which it did on some outside shots) the first owl is the focus. Both were taken with ISO 100.
f 22
f 4.5
I mainly focus on birds and flowers with my photgraphy. From my limited concept of this stuff if I wanted to take a close up of a flower then I should go with a bigger aperture to capture the whole flower and do away with the blurred egdes of the petals?
and when you took these two photos what did you notice with the shutter speed
