After a very long time working up the courage, and being in awe of some of the renders on the forum, I eventually submit one. I hope it is worthy of critique. (There is no skirting on purpose.)

First of all I think the most important question is "Exactly what do you want to achieve?"
What level of realism are you aiming for?

There is no defined scale for 3d visualisation, but if you imagine there is one, and it goes from 0 which is basic shaded geometric model with shadows and textures, and 10 which is an image which looks as real as a photo, I think you are around 4-5 on that scale.

Bear in mind that most people don't get near 10, and getting there takes a lot of skill, patience and experience acquired by trial and error. Our best Podium users get to maybe 9-9.5. The 'sweet spot' is maybe 7-7.5, because you are getting to a level which is good enough to be very convincing, without any glaring flaws which ruin the image,  while accepting that the result is still clearly a digital image, albeit a very good one.

Getting to the 8 and over mark requires quite a bit more time and effort, but we should be able to get you up to the 7 mark here without too much trouble and effort. Once we get there, you can see if you want to improve further [smile]

If we consider your image, the most obvious thing is that it lacks enough detail for a convincing render. Next the texturing needs work, and the lighting is pretty rudimentary. Furthermore the image composition is just awful. The 'cat's eye' view thing only really works well when the composition reveals something interesting, unusual or unexpected.

In your image, it's showing 30% of the area as being a fairly mediocre wooden floor texture that might be fine from a distance, but isn't good enough close-up.

You mention that you have intentionally left off the skirting boards. That's a bit like saying, I know the lights aren't that great, but I've done it deliberately. You are starting with a view of the floor, but don't even have one of the most obvious things you see at floor level, that would improve your image...

First of all, fix the camera position. Move it to floor level, and try to compose your shot nicely. If you walked into this space, the fist thing you thought of is not likely to be "I bet that would be really cool photographed from the level of the vacuum cleaner"...

It will also show up some other issues like having a picture hung on the wall at waist height.

Next we need to sort out the lighting. This is a hallway, these can be tricky, but also great renders (have a look at last year's Podium render contest second place winner Kevin, his image is on the homepage) so there is not that much natural lighting. You have to either have large windows somewhere to illuminate it, or you have to rely on indirect illumination and bounce the light in.

In the first instance, increase the sun intensity and exposure sliders, and render with the interior default preset. That will set our reference lighting level. We can get a good idea of the overall general light distribution then, and we can plan what to do if there isn't enough light.

Lighting is one of the most fundamental things with rendering. You need to understand where the light is coming from, or set up your scene so that the uniform lighting is even and natural enough looking that it doesn't matter.

Start by lighting your scene only with natural lighting. Take out any fill lighting. Turn artificial lights off to start with. If you want or need to, you can turn them on later.

Post an update and we'll take it from there [smile]
