I recently purchased a Canon EOS 80D and am just awaiting the order of a Sigma 18-300mm f/3.5-6.3 DC Macro OS HSM C Lens for Canon. I previously had a Canon EOS 1100D camera with Canon zoom lens EF-S 18-200mm. I just wanted some tips with regard to ideal ISO, shutter speed and aperture settings. For example when I am taking photographs outside on a sunny day and similarly on a cloudy/overcast day. Later in the year, I am going on a cruise holiday and was looking for some tips on ideal ISO, aperture and shutter settings inside the cruise ship where lighting may be low in certain areas than others. Should I stick to AWB setting in all above scenarios or consider changing it to tungsten or fluorescent lighting, for example in indoor settings on a cruise ship. With regard to ISO, I am aware that the higher the ISO, the more grain is likely to get into photos and I want to ensure that my shutter speed is suitable so that I avoid blur. I have been told that ISO shouldn't normally go over 800, but I don't know whether that is different on the Canon EOS 80D.
I think a good starting point is the sunny 16 rule, which basically states on a sunny day use F16 and what ever your ISO is your use the same shutter speed. There is more to this rule so my second suggestion is to look it up on you tube. ISO on a modern camera is pretty good so 800 is not a problem. My next suggestion is the most important, most men would rather have teeth pulled than look at the camera's manual. Sit down with the camera and read the manual and find out what these things refer to on your camera. Try to know the manual like you would a good woman. Lastly please continue to ask questions here on the forum as a lot of us are willing to share their knowledge.
A lot to unpack here... Let me start by saying that there is no way to give a ideal set of numbers to use as every situation is different. I wouldn't worry about going to a higher ISO if that is needed, newer camera sensors handle this better than older ones. I think you are fine using AWB, if you want to shoot a grey card and set your color balance off that, you can have more control. If you shoot RAW you can always change the WB afterwards. You really should approach the situation asking yourself what is important to you. **Do you need to freeze motion? Then start with shutter 1/(lens length) was the old adage before we had image stabilization. **Do you need to control depth of field? Shallow with blured background? (Portrait maybe) Or everything in focus? (landscape maybe) Then you should pay attention to the F/stop and set accordingly. These can pretty much drive what ISO is needed and is usually the last thing im concerned with, that said I shoot manually, and I set my ISO manually based on the valuable light and adjust if needed. Need more light then its time to learn flash
