Going to give it a try to see what happens, but I was interested in what others would have to say about this too.
Say I am in the gym taking shots of my son playing basketball.
I have the lens wide open to f/1.4 in Aperture priority mode and the camera is picking a shutter speed of 1/180 sec.
What will happen to the photos if I put the camera in manual mode and up the shutter speed so I can shot at f/1.4 and 1/250 ?
I am guessing it will be underexposed?
Even so could I still shot like this to the next higher shutter speed and correct the image with paint shop pro?

Yes, you can, but if you can set the camera for the next highest ISO and shoot "normally exposed" you'll probably be slightly better off noise-wise. If you must "push" in post-processing, you'll be best off shooting RAW and doing the push in conversion.
An alternative to full manual mode: set to Av mode and dial in the required exposure compensation. |

Totally agree with Kirbic, higher ISO as first resort. Second it to leave it in Av at 1.4 and dial the exposure under 1 stop or so. Good luck! |

First off 1/180 or even 1/250th for basketball isnt near fast enough. You will have a ton of motion blur and no tack sharpness to it at all. You really need to go to 1/400th or faster and even then you will get some blur, but it will be tolerable unless your timing is good enough. Also at 1.4 your focus point is going to be so shallow your AF better be fast and the lens as well or your going to be disappointed. I try to never go below 2.2 when shooting basketball and I really lean on the AF speed of the camera and the lens to get usable shots. Here is a link to a few from a game I shot last week with shutter speed between 1/400 and 1/500. These were shot at 2.8 1600 ISO 1/400 and 1/500. But the gym has amazing lighting for high school. I also used flash to fill in the shadow. In most gyms I'll shoot 1600 or 3200 iso and never drop below 1/320 in the darkest of gyms. Unless your shooting little kids then you can go slower in SS but If possible I'd open up the apeture to get some more DOF.

I shot an indoor volleyball game in a gym (see After the game entry). I got some interesting affects for volleyball serves with motion blur of the serving arm.
I tried to rapid-fire shots at the peak, following the player and anticipating the movements. At the top of a jump or when retracting, before shooting the ball back is the peak where there is a fraction of time that has less motion.
I was using my Nikon f/1.4 in a dimly lit gym, intending to zoom-in more in post-processing of the 10MP raw files. |

The shutter speed you choose (1/180 or 1/250) may or may not be fast enough. Choosing the right shutter speed depends on several things... mainly how close you are to the action. If you are shooting close to the action, you need a faster shutter speed. If you are shooting from more of a distance, a slower shutter speed will probably work.. maybe even as slow as 1/125". If you are shooting from the baseline, you will quickly find out that f/1.4 is a bad choice of apertures. I shoot a good bit of basketball from the baseline and I have been using my 50 f/1.4 for a good bit of it, but I normally shoot at f/2 or f/2.2. The depth of field is so shallow at f/1.4 that you will have a hard time getting your subject in focus, especially if they are moving towards you or away from you. Your best bet at f/1.4 is if they are moving laterally to you.
I also agree with Kirbic... Push your ISO up before you underexpose. Correcting an underexposed photo often creates more noise and other issues than shooting at a high ISO.
