Sony DSC-F717

[blaz]

Hi,anybode can help me with my cam setting?,I need some setting help.

i just realize recently when I need to print the images in a3 size, then i can see the pixel is so big.though I shot the image in 2560x1712. especially in the human skin.

I took the shot using the speed in manual,autofocus, sharpness +2, the rest as standart.

I try to upload the image here,or i can email to you the original image.

 

Thanks in advance,

umm...not really clear as to what problem you are having. Sounds like you simply need to resize the image Photoshop or any other image editor. If you need more help just ask.

i am not really sure what you are trying to do, but here is my input...

 

you want to print a3 size from a image that is 2560x1712. a3 size in english measurements is 16.5"x11.7". the proportion of 2560x1712 is different than 16.5x11.7. you will need to crop some of the image off of the top or bottom, so that the size of the image is 2414x1712.

 

you want to crop off the top or bottom because your lowest resolution is in the width. cropping off the side will force your image down to even a lower resolution.

 

a resolution of 2414x1712 at 16.5"x11.7" will be a resolution of around 146 pixels per inch. this should be high enough to give a decent print, but is far from ideal. everyone has an opinion of what the best resolution for print is, but i think the professional standard is 300 ppi.

 

so if you need a professional quality print, you will need to re-shoot the image at almost twice the resolution. alternatively, you could try to slowly sample the image up in photoshop. this should eliminate most of the 'pixelization', but the image will still be blurry.

 

by slowly sampling up i mean increasing the resolution from 146 to 170, then 190, then 210, ect.. or something like that. make sure you use 'bicubic' re-sampling in photoshop when you do this.

hi, thanks for your quick reply,

any specific setting that can cause this probs. hopefully it is just a setting issue. just so waisted if i can shot in big image size but then i have to trim down to small image.

 

thanks anyway

It's always a good idea to shoot an image at the highest resolution your digicam will allow. You can always rezise the image in an image editor. Sizing up is a different issue altogether. I have a Sony DCS-S85. It shoots up to 2272x1704 pixel images. I just simply down-size to my print size. I usually print at 150dpi. THe iamges come off the camera at 72 dpi - just change it in Photoshop (I turn off The only time I ever go lower on the camera resolution is if I know I will be shooting hunderds of image in one day and my Memory Stick will run out of space quickly if using the largest size. I have a 128 MB SansDisk Memory Stick that holds maximum 70 jpegs at 2272x1704 (color, finest quality, sharpness at 0).

 

This is how I usually do it:

thanks again, but thats not what i meant.

I think i explain wrongly here.

I understand that portion where i need to change my image size down,

i try to post my partial image here, I crop this image from the original file, maybe you can see the pixelize there.

 

I realize this probs also because i compared the result from my friend's camera, he's using the canon ixus.it's a small camera, but his photo is much clearer and clean,

 

thank you, thank you for explaination. and sorry for my poor english.

OK!! I understand now. Well that would be called "noise" I think. Try different compression settings (fine vs. standard) or also maybe try shooting TIFF mode (very large files but no compression). One thing about digicam's is that in lower light levels more noise shows up.

[blaz]

so, this "noise" things are common is it?

no way i can get rid of it. I mean from the camera itself, unless I compress again in the photoshop.

 

that's help a lot. at least i know what i get from the cam, so I will not expect to high later on

 

thanks to both of you.

Dunno if you've read this before but this site has helpful reviews. DPReview.com (review of Sony F717)

 

Blaz - I forgot to mention ISO. Make sure you set your ISO to the lowest setting of 100, don't leave on AutoISO. THat should help the compression but will lower your shutter speeds. Remember, lower ISO always creates slower shutter speeds - this is true even for film.

[blaz]

thanks man, I'll try another shot.

[blaz]

or maybe trade in that camera

just now my friend show me his photo using nikon, the "noise" much more softer that my sony.

anyway, thanks god we havre photoshop around.

hi xavier,

i have follow your advise regarding the iso, i works, and then i use the speed priority to shot and give more and more xtra light (i mean) reduce the speed,

the noise become softer, so i guest the image that i took last time also because they lack of light as well

[xgarcia]

90% of the time I shoot in aperature-priority mode. I like to be able to control the depth of field in the image. The other 10% I shoot auto-mode with the flash on (for snapshots). I usually keep the ISO at 100 and the sharpness at 0. I guess any noise that shows up you just have to live with. Like I said, it's a drawback of the sensing chip on the digicams.

 

BTW - your Sony F717 was the top of the line model last year. I was looking at it but decided for the cheaper S85. Both have the "Carl Ziess" lens, although the F717's is much larger.

Blaz,

 

You might also see if your camera has a noise reduction setting. I have a Nikon 995 and I'm able to turn on noise redution to clean the image up. The difference is quite noticible on low light or long exposure shots.

[Jeff's Friend]

I have the DSC-F707 (the predecessor to your camera) and I am very familiar with the settings. I think the biggest reason you're getting a lot of noise is because you've set the camera to "SHARPEN +2". First of all, all Sony cameras oversharpen to some extent even when set to SHARPEN +0 (relative to cameras from other brands). The advantage to sharpening is increased illusion of edge detail. The disadvantage of sharpening is the introduction of noise (patchy color variation amongst adjacent pixels) into areas that are supposed to represent smooth gradients of color (like skin, solid colored clothing, etc.)

 

I would reduce your sharpening to +0. I would also set your ISO to 100 like another poster suggested. Make sure you're using the "JPEG Fine" setting. Using a tripod always helps. And, of course, as with all digital imaging, the more light you can shine on your subject, the less noise you'll get. Digital cameras and camcorders just don't do very well in low light yet....

thanks guys, for sharing ur info
