Really got into photography now.

Using raw mode for better quality, took some with the sun just before setting with good results.

however went out today to take some pics of the cloud colours just before sunset (when they are red etc), took 30 pics and 2 of which are only just veiwable.

People say its iso settings, so i took the same pic with every iso setting, from 80 to 2000, and auto, and i get the same graininess on the photo.

Now i have £600 and im tempted to sell the s9600 for £200 and buy an EOS, as my mate just bought one and managed to get a perfect shot on his first go :rolleyes: and hes learning from the same stage as I.

has anyone else got the s9600 and having problems ?

im taking the pics on M mode (manual) as shutter speed doesnt seem to make any difference to the pics.
 
Post an example.

Shutter speed will make a difference, too slow then it'll be too bright and blurred (unless using a tripod). Too fast and it'll be underexposed.

Well first shot you are suing ISO 800, and second ISO 200, so that will make a fairly big difference.

That's going to be the biggest cause of noise at a guess. I would suggest taking some time to learn the basics of photography (after all you do have a perfectly capable camera) before spending £600.
 
Also underexposed shots will produce noise in shadow areas even on a DSLR. Expose to the right and make it darker in Photoshop. Turn off sharpening in your RAW converter and only shapren at the end of the processing. Invest in some decent noise reduction software if you want to use 800ISO (Noiseware pro is great for this sort of thing). You should be able to get some very good results with the 9600.

so let me get this right

outside, when theres a lot of light, i need the lowest iso ?

inside, when there isnt, i need the highest ?

Yes.

Generally, as a rule, keep it low, unless the shutter speed is too low for the aperture you want (or the aperture can't go wide enough for the shutter speed you want) and then increase the ISO to compensate.

Say you want a shot at 1/300 at F8 but when you set it to F8, the camera selects 1/250 instead. If you increase the ISO from 100 to 200, it will allow you to use 1/300 and still get the correct exposure.

Hope that helps.
 
One other thing, are you sure it's noise you're talking about?

Because you are getting some absolutely horrific Jpeg compression artefacts on these images (hardly surprising on a 9MP image that's been saved at 500KB, i'd be expecting 500KB for something i've resized to like 800x600 for web use)

(versus your 'good one' which is reduced size (1600x1200, 1.9MP) and 650KB)
 
That's a good point, what are you using to save them eracer? If it's photoshop set the quality to max when you save the resized image.

Here's an example:


Max quality Jpeg (12):

Low Quality Jpeg (3):

Even with this fairly small image the difference in quality is very noticeable.

have you read the manual yet?

it still seems that you're not understanding what does what in your camera - and selling a wonderful bridge camera and buying a dSLR will not help you take good shots unless you know what settings do what.

i learnt quite a lot from those lessons, and as such i havent needed to post here as much asking questions. Lesson 1 and Lesson 2 i would draw most of your attention to.

and if you havent done it yet, RTFM!!!
 
My girlfriend uses the s9600 and gets great shots. Either your ISO is too high, your jpegs are being saved at too high compression or your camera's borked.

It should take ace pictures TBH.

I'll get some images off her to post so you can see what to expect from your camera!

I'm taking it that you haven't learnt from the last time you posted on here and quite frankly I can't be bothered to help people who can't be bothered to try and help themselves in the first place.

Why are you using Raw mode, other than reading what people use on here? It looks to me like you are losing a lot of quality converting from raw to jpeg. Try switching back to jpg mode.

Ok. ISO ratings are the equivalent to the film speed on 35mm films. Lower ISO = less noise on the picture, but requires a longer time to expose (will need a longer shutter / wider aperture). Higer ISO is quicker to expose, so you can get away with faster shutter speeds, but they can introduce a lot of noise. ISO800 and over will produce noticable noise in low light.

I always try and stick to the lowest ISO possible. If you are shooting in low light then balancing your camera on a wall / using a tripod and using a long shutter speed which produce nicer photos than using a higher ISO and a shorter shutter speed.

Don't do this. You will experience the same problems as you are now.

Shutter speed makes a big difference. Shutter speed is the amount of time the shutter is open and the sensor is exposed to the light. Obviously the longer amount of time the shutter is open, the more light gets in, thus making a brighter photo. Edit: Should probably also be said that with a longer shutter speed, the photgraphs can be blurred as it becomes more likely that the camera is moved / knocked whilst the shutter is open unless it is on a tripod.

You should really read the manual, as all of what I have said is basic stuff which you should really know...

Also, from the looks of it, your learning from a pretty basic stage (forgive me if I'm wrong) so I wouldn't suggest jumping straight into manual mode, as even the best photographers don't use it all the time. Try using aperture or shutter priority mode to play around with the settings, while still retaining some degree of automaticness.

I disagree there, I think the quality loss is purely due to the fact he's choosing to save a 9 megapixel jpeg at 500KB, which is nowhere near enough. All my 6 megapixel jpegs are around 6MB, 12 times the filesize for two thirds of the image size.

If he resized to 800x600 and then saved at 500KB i'd be willing to bet all his artefact problems will just vanish.
 
Fair enough. I just don't see the need for the added complications of converting from raw to jpg at his level. Added complexity gives more room for error ;)
