Default First attempts canon ixus 400

Just thought i'd post my first attempts using my new canon ixus 400. Im new to this whole photography thing. It was an ugly overcast day so the sky looks overexposed and i noticed some purple finging.

I also tried out the photostitch software. Again bad overcast day.
I also noticed some banding type effect where the photos joined. This is a large inland lake between canberra & sydney australia. It's approx 170 square kilometres in area. The water level rises and falls independant of rainfall. But most of the year it's empty and sheep graze on it.

On shots 1,2, 5 and possibly 3, your white balance is off. You can correct that in Photoshop or equivalent. The closeup of the bolt in shot 3 is excellent. The color may be off slightly but not sure. The color in shot 4 appears to be ok but if it were me, I would crop off the bottom third of the picture. Your subject is the steel railroad trestle and the weeds in the foreground pull your eyes away from the bridge.

On the stitched panorama, the difference in color or shading at the joint is because you had the exposure in auto. When shooting a multipart panorama, you need to put the exposure settings in full manual. Take your exposure reading on the middle shot, lock that setting into the camera, and then shoot all shots with the same setting.

The reason you don't want to use auto exposure on a panorama is that the camera will "read" each section of the panorama and set the exposure according to what it sees. The problem is that no matter how uniform the lighting seems or texture of the shot, there will be variations from left to right. This will result in the different sections of the scene to have different brightness levels.

Good luck, my friend and keep trying. I am not familiar with the camera you are using but it looks like it is capable of great shots.

Thanks heaps for the feedback Calr,

I think my camera sets the exposure etc. when i focus and there is an option to lock the focus, so i think thats what i need to try.

And thanks for the tip about white balance, the camera has a few different white balance settings and a manual mode. Next time it's cloudy i might use the cloudy setting

I cant see in PS where you adjust the white balance?

I use Paint Shopt Pro because it is a lot cheaper than Photoshop yet has most of the same functions. Look for something called color balance or auto color correction. In PSP is in the Effects menu.
