How Do I Improve Overall Image Quality?

Sat Jul 17, 2004 3:20 pm

I've been taking some photos with my Sony F717, and I am not really pleased with the overall quality of the photo. I would like to take photos that meet the A.net standards. These are the settings I usually use when taking photos of planes:

ISO: 100
Image Size: 2560x1920
Picture Quality: Fine
Mode: P Mode
Sharpness: -2
Exposure: DEV (or is it OEV?)
White Balance: Auto

Here is one of my pictures. This one has been sharpened using the Sharpen More feature in Adobe Photoshop. Unfortunately I can't find the original version.

Full size image can be seen here.

So how exactly can I improve image quality? Should I be changing my settings. I'm thinking the problem could also be motion blur, but I generally don't shake the camera.

Thanks in advance!

Try taking pictures earlier on or much later. The shadow shows the sun is very high up in the sky. The light is very harsh and bright.
Try evaluative and spot metering. Also try the Tv-program, where you set the exposure time and the camera chooses the appropriate aperture.
When taking pictures of slow targets such as this one, you can also use the Av-program, where you set the aperture and the camera sets the shutter speed.
When you look through the viewfinder, the aperture and shutter speed readings shouldn't be blinking, if they are, change the settings.

Choose shutterspeed values of 1/250sec and higher for slowmoving targets, 1/500sec for planes in flight. Aperturevalues of f/8 and higher should produce enough depth-of-field.

Once you've practiced a little bit you can experiment with shorter shutterspeeds/larger aperture combinations.

Try not to use the Sharpen More feature of Adobe Photoshop. I prefer using Unsharp Mask (USM) to sharpen my pictures because it gives me more control.

Hope this helps.

That A321 shot of yours don't look too bad. Rotate it a bit and it's alright.

Definitely use USM instead of sharpen more.

Yes I usually do use Unsharp mask, but just for this one I felt that the Sharpen More tool worked better.

Are there any other suggestions on how to make the photo sharper?

I used SharpenMore for a while... But I always faded it to 60-70% or so... Now I use many (2 or 3) passes of USM at a low setting (50, 0.3, 0)...

the sun looks to be all wrong, and you've used the auto color, contrast feature, lets see the raw image, straight from the camera.

ClickHappy,
Unfortunately I can't find the original picture (I think it was deleted by mistake). I agree that the sun appears to be wrong. This picture was taken at about noon. The F717 has is a feature called the white balance. Normally I leave the white balance setting at Auto. However, there is a daylight setting for the white balance feature. Should I change white balance to daylight then?
I'm also noticing that in most of my photos the sky is darker than it really is. In other photos, I notice that some planes seem to be overexposed. I have severa Air Canada 767 shots in which the plane seems to be too bright. However, I notice in photos with planes with darker liveries like AA's everything looks fine.
Any suggestions on how I should change my settings, etc would be appreciated.
