Hi all,

Need some advice. I am rendering all the images for my webpage 1:1, after doing some post processing in PS I am developing an issue with regard to jagged lines. I know that I could render them at a higher resolution, but that would mean I have to re-render all, which I cannot afford to do right now.

the webpage is www.brio54.com and is still a work in progress in terms of renderings

Does anyone have a fix for me.

Thanks,

Gernot

Hi Gernot, are the images being resized by the application you're using for the flash content creation?

If so, this will introduce jagged lines to your images.

If you set the resolution in an image editing package, to the size they will be used on the site, then you shouldn't get those lines.

If it's the post work you're doing and not the image beiong resized, then let the renders cook for longer. You will be able to resume the renders to do this, without having to rerender from the start.

I find using the 'Equalize' in image adjustments, will enhance noise levels and increase the visibilities of any imperfections, fo an image which hasn't been rendered for long enough.

Thanks Tim,

No resizing with flash. It is the equalize post that brings out the imperfections. Just as you said. They are already cooked up to 19. Will 20 do the trick? I think it adds an extra 2 hours per image on my Q6600.

Usually I think people render it at 120% or more, but this also takes more time. Would re-scaling software for large prints help ?

...... Blow it up, do the post and then resize after it and sharpen. I would have to pay for it, so I don't want another useless software around.

How long is a piece of string?

It could improve it, it might not. It's the trouble with scenes that are different. It means tests for one scene cooked to sl20, which may give fantastic results, will not do the same for a different scene.

It depends on elements in the scene, caustics, glass, sss, displacement etc etc.

Alien Blow up is a good reasonably priced plug in for PS, which works well and has a 30day trial.

Neat Image will also help to some degree. This also has a trial period.

I tend to use the fade option in the Edit menu for PS, immediately after using the Equalize feature.
Using a 'Screen' blend faded to suit, then re-equalize and use a 'Soft light' blend adjusted to suit, will give me the look I like. Although on undercooked images, it has to be used sparingly.

Thanks Tim,

It is hard to get a coherent render platform. That is why I already got rid of the physical sky and the sun, glass, ... but it still varies to a small degree.

I am duplicating the original layer and then perform all the operations on an overlay blend. Too simplistic I guess. I will try it your way. Thank you very much for the tip.

Glad to help Gernot.

Fading equalize with the Overlay blend, will also give nice results, but I tend to try soft overlay fade too, and use the best result.

Great renders, Gernot.

Great tips, Tim.

Cheers.

Hi Gernot - great renderings and great site! congrats!

In Maxwell you should not have to worry about antialiasing - just render to a higher SL. remember: Maxwell is a camera!

If I understand it correctly - you render to the same size that you show on your web-page?

I suspect that your problems has something to do with a method you use in your post-processing/ or in the flash app, but to confirmn that I have some questions first:


1) Are you sure that you render to the size 800x400 pixels?
2) How do you add the black border line?
3) do you know that your pictures are 798x399 pixels on your webpage? If I count in the black line they are 800x401 pixels.

If you are using some smart program to add the black border on the outside of your rendering AND still keep the total image size - jagged lines will be the result - just like the ones you have.
If you use Photoshop and the tool Canvas Size to add 2 extra pixels height and width, you will get a perfect frame line, but your initial render should be 798x398 in Maxwell to avoid any resizing.

Thanks kurt,

I am trying,.... I really need your advice on this one. I checked all the flash
related stuff, but no scaling there, just a script to externally load the jpgs into a movie
container and all images are 400 x 800 px , the boarder is in the movie, not on the
image. The image is as is. If the flash file would scale the pixel fonts would show that.

I had to sharpen them now, to match the going style, .., which made it worse
in the high contrast areas. Since the page is in circulation now and I am getting
quit a bit of traffic I really need to resolve this.

The SL for all the renderings is 19, which is already high for exteriors. Do
you know of any software that can address this one ? maybe a blowup printing
one that adds details?

With regards to the image size you may see the border that is on top of the
image container.

Thanks,

Gernot

hi gernot,

I guess my theory was wrong, but maybe you could post one of the original renderings (maxwell version) so that we could compare it to the final version that appears on your web-page?

[ab]

hi kurt,

Sorry kurt, very busy since we are starting to take off,.... I am still having the old contrast issues. It is driving me insane. Looks decent on one monitor, looks boring and washed out on another. This is why I have to give it a serious post treatment. I will email you an original, rather not post it.

nice shots! especially the one showing the interior!

If you're really sure there's no resize at all, i don't know what it could be else

I dont find Alien Skin to be that good especially if you blow up with noise. It tends to recalculate the noise weirdly/worse.
