I am! New camera, new lenses, no more "point-and-shoot" :)

I welcome all your critiques - it WILL only make me a better photographer......

Generally by bad quality lenses. I'm not kidding when I say that my £150 Canon A70 was never that bad. I know you're new so I want you to know that this really isn't the kind of image quality you should be getting from your D50.

Very true, the D50 produces superb image quality for its class and rivals more powerfull 8mp cameras. The noise is there and it is visible. I would suggest changing the Image Optimization settings to 'Softer' and usung ISO 200 or 400. It would appear that the camera is set on +2 Sharpening and +2 Contrast which is having drastic effects on the image quality coupled with that lense. Just my thoughts anyway.

However like i previously said noise can have positive effects aswell.

King.

I understand noise to be that grainy effect. Is that correct?

Yeah.

Image noise corresponds to visible grain or particles present in the image. In the context of digital image processing, the term noise usually refers to the high frequency random perturbations of color values of size close to 1 pixel, which are generally caused by the electronic noise in the input device sensor and circuitry (e.g. scanner, digital camera). There are other artifacts of similar appearance which are referred to with different terms to underline their origin (e.g. scanner streaks, film grain).

Thanks. What actually causes this noise, (electronic noise).

im a newbie myself so heres my attempt at explaining it, apologies to all if im wrong :p

the main cause for noise is down to the cameras ISO setting, which in basic terms is a degree of sensitivity to the current light. This means that the higher ISO setting means more sensitivity which can create more noise.

In the case of the OP's shot the noise seems abnormally high for a 400 setting.

Increasing the ISO ups the gain on the sensor, and that increases apparent noise levels.

I suppose you could think of it like turning the volume up on a stereo, hiss and other background noises also get increased.
 
The noise on that Bee shot it because of cropping. A 50mm prime can't get that close for a start.

A combo of low light, jpg compression, high ISO and serious cropping will create that noise easily.

Anyway, it's a good start for someone starting out. Nice to see people experimenting throwing rocks into water and that. Don't give it up.
 
it's all very well and good that people are trying to learn, but no one will ever learn if you constantly tell them their photos are great when there's serious room for improvement. when i first started posting photos on here, most of them got ripped to hell, and it forces you to go out and really think about it.

the composition on the first is good, i dont like the idea of the second one at all, and there seems to be a lot of burned edges in those droplets. i've seen a couple of shots come out like the first one from my 50mm, and i think the ISO isn't helping that. i hardly leave ISO 200 if i can help it. try playing around with shadows and highlighting in your processing to eliminate noise. personally, i dont think that lens can cope with a subject so small as you're forced to crop the hell out of it!

I totally concur with that point, I like critisism like that, at least I know I have things to improve on. There are a couple of members here that'll simply just post "great shot" or "nice shots" in a photography thread. That's nice and all but sometimes the point has to be set across. Again, not being harsh here but some of Gamefreak's shots in the beginning were rather 'unmentionable' but now he's got some feedback he can learn from that.

Agreed. I've also seen some silly "Great shots" comments. My early shots were rubbish, really bad flower macros and random shots of stupid things. Slowly though, thanks to the people here, I've gone from "What the hell?" to a professional photographer. Constructive criticism can work wonders.
