You actually have both integrated in your D70.There is a film counter. It is located in the right hand bottom corner of the screen that shows you speed and appreture. The screen is on top of the camera body to the right.
All information such as day, time, ISO, speed, apreture etc. is recorded electronically in your picture file. You can see this info if you open the files in a photo software.

No camera can cope with a situation where the sun is blocking our the viewfinder. Shoot with the sun behind you and not directly into unless you are looking for a funcky look.

When in Rom, do like the Romains do. A very old saying but it also applies to your question. The photographer should be respectful to the couple and dress business like, but not too different from the other guests.

No problems with your D70. The problem is the exposure setting. All three pictures are underexposed. After taking a picture, look at the histogram that the D70 displays. In order for a picture to get the full spectrum of shades, the curves should start and end at the beginning and ending of the historgram window. If not, you have a problem. Software like Photoshop Element lets you adjust the histogram by moving the arrows to match the spectrum displayed.
Your problem could be the setting of your exposure mode. In situations like yours, you might want to increase the exposure correction by + 1/2 stop since you have no contract in the picture and the average shade of the scene is darker then the average grey. 18 %
Good luck, I work with the D70, a wonderful camera.

Happens to me mainly with the new multi Giga cards. Can't read them with a card reader, but it works if I hook the PC up directly with the camera. Good luck.

I like this picture very much. Tempted me to play around with it. I hope you do not mind.

18 - 105 would be my choice.

Mothers in law should be a reason alone to stay away from poligamy!

Photo is good. Guy sucks!

Open the picture in your software, open the color control menue, select the "blue channel" only, desaturate the blue and you are there.

Beautiful bridge, I hope you like the touch ups.

Great picture. One piece of advice, always watch out for the little details when shooting a beautiful girl - the hairs!
Not bad in this picture, but the loose hairs on the right shoulder could become a distraction in the next move.

Great tree!

You need flash for such assignment! Sport actions are dynamic, needs tension and suspense. Freezing the peak of a move is essential. Soft focused slightly blurry and candle light colored pictures are romantic, not a good match with actions in a gym.

Try a simple trick. Tilt the flash head toward the ceiling and bounce off the light from the ceiling. You will be surprised. Make sure that the model is close to a light background so that light is also reflected back. Avoid shooting flash into an empty room. The space swallows the light.
