Hi Tony, As far as the "hot button" setup, it is different between our cameras (sorry) so you will need to look it up in your manual. I use the 500 series but they are really similar.
Another thing to watch for, keep you ISO as low as you can go. I try to keep mine at 100 as this produces much clearer and less noisy Images. Now, on the night / low light shots, you can use your auto settings (they work very well) however a few things to note.
Before setting the camera to night mode, make sure it's ISO is set to 100. Then make the selection.
When you change back to ANY mode - be it auto and Portrait or macro etc. your ISO will change to the higher ISO range, so go in each time and lower it manually.
When I set to Custom WB, I keep a coffee filter (anything Bright White) to hold in the area that you'll be shooting, I press and hold my set button and press my shutter and press the OK button and viola, I have the PERFECT WB for that shot. The Auto WB works fairly well "if" you have (TRUE) white in your background that the camera can see. It's brain will seek out the White in any background to set the WB. It's very effective but it NEEDS to see true white in order to establish a true WB.
As for the ISO, like I said, I almost always use 100. There are times though when I need a faster shutter speed and can't (or don't want to) use any flash that I will step it up, but then I may have to deal with some noise. It's a trade off but for the most part, I keep in the 100 range.
There's a NR feature on the camera that I don't use, and the NR in PS is not the greatest. I have heard of a better NR filter for PS that I will hunt for when I get the time but for now, I try to provide enough lighting for my subject the old fashioned way - I drag out the Studio lighting.
When you play around with your manual settings, you will find trade offs - faster shutter speeds can mean higher ISO's and you make the decision as to what and where you want those trades.
Your camera (with EXIF Data / Meta-Data) can teach you more than a Photography School and a lot cheaper as well. Take lots of Photo's and change your settings, take notes as to what your settings are and study your results. I know it sounds very basic, but it works very well. I've been doing this for many years now and I am still learning.
I belong to several Photography Sites on-line and there's one in particular that I use to study a LOT of Photographers Internationally. The Site allows FREE memberships that allow for 4 uploads daily, the Exif data usually uploads and is shown with the Photos, people (members) can rate and comment on the Photo's. This is where I spot a Photo that I like and I investigate and read the Exif Data, this tells me how the Photographer set his / her camera so I can try it too. The name of the Site is Eyefetch you can find it at
www.eyefetch.com If you join, look me up, last week I was promoted to Site Co-Administrator. That's why I haven't been on here as much lately. My name there is the same as here; Jelderkc - If you join, look me up and send me a Friends request.
Have a "Picture Perfect" day,
