You changed your exposure value by 3 full stops, so yes, that's going to affect the EV of the image.
Thanks for that, I thought aperture was all about focus distance, and there was me thinking I had learnt the triangle 1Hi Keith, as you can see on the diagram below, they all have an impact on the exposure. If you're shooting in manual then you'll need to slow the shutter down as you narrow the aperture to get the same exposure as you would with a wider aperture.
Thanks AlanKeep an eye on the aperture, shutter and ISO settings Keith. If your camera has auto ISO it might be an idea to see how you get on with auto ISO selected but also keep in mind that higher ISO's can give more noise. If you don't like auto ISO you can always increase it manually to get the exposure you want with your selected aperture and shutter settings.
Also, many people tend to manually focus when doing macro as with AF the camera will focus on something but that something might not be the best choice. What you could do is use AF to get you near and then fine adjust with manual focus.
Actually... another little project for you could be to use all the ISO settings and see at what point the image starts to be affected by noise too much.
Good luck with it

That was really good, thank you.Agree with David above.

Thanks Alan, there's not a lot of aperture adjustment on my little camera, but it still needs to be understood. Somehow I managed to get things the wrong way around and thought F2.8 was best for landscapes and scenery ! Much appreciated.The aperture is the hole that lets the light in. A wide aperture, a low f number like f1.4 is bigger than f8 and will let the light in faster allowing a faster shutter speed / lower ISO. It also gives you less depth of field.
If you have a wide aperture lens the best thing you can do is experiment... like taking a series of pictures at different apertures and seeing the results. Oh, hang on... have a look at this...
Differences at f1.2, 1.4, 1.7, 2, 2.8.
Just out of interest. The difference between f1.2 and f1.4 for DoF and bokeh has cropped up a couple of times so I thought I'd post a series of pictures. Note that I'm ignoring light gathering here and just looking at depth of field and bokeh. I looked at bokeh and depth of field years ago and...
Keep at it Keith. You seem to be making great and fast progress so I'm sure you'll soon to on top of just about everything
That's good advice, thanks Alan.It's your choice Keith.
Some people think that landscape should mean wide focal length lenses and small apertures (big f numbers) with everything in the depth front to back but there are also people who like long lens landscape and even wide aperture shallow depth landscape.
You should try it all and see what you like

Thanks Kev, much appreciated.My Pie chart alternative to the triangle - may, or may not, be helpful
Beginner - Exposure Triangle?
This post is meant for beginners and gives an alternative to the Exposure Triangle. Experienced photographers, especially those who grew up using film, no longer need to think about how to set or change exposure and more recent photographers have probably understood and accepted the Exposure...
