big resolution image rendering 40000x25000 px

[aristocratic3d]

Hello guys!

One of my clients is asking for a big image. its around 40000x25000 px(forty thousands x twenty five thousands) pixel resolution.

 

Is that some thing possible in a corei7 with 12GB ram in it. with 1gb graphic card?

If not please let me know what minimum size I can render for him.

 

Regards

A

Just tell him he's crazy and that an 8000 pixels will do fine.

 

I just had a client just last week ask for

1. Rendering DPI (600 preferred)

2. Rendered image size (24” x 36” preferred)

 

This makes almost 15000 pixels. Told him 6000 would be fine and that was it.

 

Clients hear someone saying bigger is better and they run with it.

This in mind I did render 14000 pixle swide images before, I used to do it all the time, clients used to zoom to the pixel level and comment on one wrong pixel. you're just shooting yourself in the foot by providing that (and at no extra cost too), 6000 to 8000 will print fine any size.

I once made 80 meters and 55 meters long billboards at insane resolution. printer person printed it low resolution to save ink to save money and I discovered I wasted my time. Plus these wide format printers are not high dpi as the small ones are.

I doubt your machine would be able to render even half of that resolution, I can't think of an instance where you'd need something that big even if it's a massive billboard. What people forget is that these large signs are being viewed from a long distance and you don't need the fine pixel resolution for that type of viewing. On large signs I've used 50 dpi or less depending on how far away the viewer will be from it.

Thanks for the suggestion mate.

I e-mailed him with a quotation that is two third the amount he paid for the project. No way.

[aristocratic3d]

Exactly. My machine may crash to do that. so if that image 72dpi then it will stand something around 9000x4500

I think this is not bad. I will tell him for sure.

 

Thanks for the comment.

Images this resolution are occasionally needed, but you need to know parameters of how and what it is going to be used for before you decide if this is overkill. As pointed out above, if this is for a billboard it is overkill, but if this is to be viewed on a wall from 3-4 feet away and printed 20 feet wide, then it could be possible that everyone of those pixels will matter.

 

So, rather than looking at pixel dimensions ask the client what the final print size will be, how it will be viewed, and at what distance it will be viewed. You need to have a who, what, when, where, why conversation with your client before you embark on this.

 

Next, how complex is your image? How many lights? Are you using a lot of glossies? What are you sampling settings? Etc.. I can render a 40,000 pixel wide image of a white box with relative ease, but a full airport may cause quite a few problems.

 

If you do need this image, then you need to make use of extensive proxies, maybe tiled EXR's, low sampling, and render to a Vray image file. There are others tricks, but those are going starting points.

I generally agree with all of the points above regarding resolution. All of that said, if it were absolutely necessary for you to render an image that size I would recommend you use backburner in strip rendering mode and assign the job to your one PC. This will break the image down into managable chunks for your computer and then recompile them into an image once all of the strips have rendered.

Actually this is the solution I needed. I knew I cant render that big. But I also knew there is a solution.

Also thanks everybody for your informative comments. Some times I feel great to be a member here.

EvenI Had almost same problem it use give error can't create bitmap ! Then i shitted 64 bit OS problem got solve but rendering resolution is not huge as your and there is option in render menu Print size assistance, that could help you out !

Render it out smaller and download Blowup plugin for Photoshop( trial version is the full valid for 30 days I think)

the quality is very good. Check it out
