Default Bad Photo Quality

Hi everyone!

What exactly is bad about the quality of this picture?

http://www.railpictures.net/viewreje...&key=286850195

This is a HDR shot taken with a Sony a33 which has a automatic HDR feature.

The lens flare in the sky around the lamps, and upper right, is pretty bad.

Also, the shot is not sharp at all.

Soft, bad color, unlevel. I agree with J, the light flair is ugly.

I'd probably stop shooting on the "automatic HDR feature" to start with.

bam.

Try to avoid points of light with night exposures especially long exposures. You have to look at this the way the camera sees it, the entire image here the camera sees maybe a 5 or 6 second exposure except for those lights they should be 400th of a second. Even the auto HDR mode doesn't know what to do with that kind of gap in shutter speed.

Another thing, I know those Sony bodies have built-in image stabilization into the body, turn it off if you're using a tripod at night. And invest in a vintage Minolta 35-70 f3.5-4.5, they are about 20 bucks and were the "kit glass" on the first-generation Minolta AF bodies from the 80's. TACK sharp comprehensively annihilates anything Sony has to offer in that range that doens't cost as much as a mortgage payment. I have one on my Minolta Maxxum 4, wows me every time I get prints back that were taken with it.

Right. That does make a lot of sense. It ain't easy avoiding sources of light at night, especially at stations, yard, etc...

I did not know that image stabilisation had an impact on picture quality. I'll definately try turning it off when using a tripod. I'll also look into those Minolta lenses... I hear a lot of Minolta lenses fit on Sony alpha bodies, guess that's why you're mentioning this one here...

Thanks a lot for taking the time!

Another lens you might want to look for is the Minolta 70-210 f4, called the "Beercan", another one of their gems from days gone by. Not the f4-5.6, the beercan is solid F4 through the whole range. The Tamron 70-300 LD Macro 1:2 is another gem I have it, tack sharp.

There is a LOT of vintage Minolta glass that performs flawlessly on the newer Sony Alpha cameras, I know guys with all-Minolta lens collections on their Sony. Not ALL Minolta lenses, their later kit lenses that came with their mid-range Maxxums weren't all that great, but the 35-70 is a must have for any Alpha-mount photographer.

Check out dyxum.com when you get a chance, it's an all Sony-Minolta forum a lot of knowledgeable people there who can show you some neat tricks with that camera of yours.

Got me a 35-70 on eBay. Should be here tommorow! For 25$, can't go wrong!

I'll look into the Beercan as well, although I'm not a fan of heavy zooming (yet).

Thanks a lot for the advice! Much appreciated.
