PhotoWorks is driving me nuts!

I have done renders (jpg) of 20 similar products (smooth wall
aluminium foil trays) on a plain coloured background.

I have replicated all Photoworks settings for each render, however,
when compared side by side there are marked differences between each
product such as:

- the backgrounds appear lighter/darker in some instances
- the aluminium foil is duller/shinier in some instances
- on some trays some of the edges appear to have a bluish tint


I am guessing that this is due to each tray refracting/reflecting the
light slightly differently.

Does anyone have a trick up their sleeve so I can make each render
look the same.

Also, I am in a debate with my client over image size/quality, he
wants 2 versions of each render, one low resolution (up to 5MB) and a
high resolution (up to 20MB), he wants to print at A4 size maximum,
can anyone comment on this as I feel the 20MB version may be over the
top, in fact my renders are alll coming out at around 500-600KB at
300DPI and A4 image size

Thanks,

Why dont you render tiffs- they dont have compression, and if it is
file size he wants thats what he will get.

I am not sure why you have a difference in renders without looking at
the file. I might suggest creating a render assy, setup with a camera,
and then swap out the different trays in this render assy. I have
achieved relatively consistent results with this.

 

Parel's idea is a good way to go. As far as the background, go with
white or use an image format that will save the background as an alpha
channel and it will be transparent. This should take care of any
color differences.

 

Thanks,

The render assy method sounds like it would do the job - I've never
done this before so any tips would be good.

As for the background colour this is the clients corporate colour
(R=54, G=42, B=38) so I'm stuck with that.

I suggested TIFF's at the outset - due to their lossless nature - but
the client insisted on Jpg's.

Thanks for the help anyway,

Ok. So save your image with a transparent background and merge it
with a background of the corporate color in an image editor. It will
be correct every time.

 

I'd thought of that but the models throws shadows, do you know if
these would still look realistic using this method? - I guess I should
try it.

Thanks,
