Your tip in Printing in Indesign--working with high quality images

Question

Hi everyone,
I am very curious about what the other professionals' idea about printing and using Indesign to print.
I am working on a project that with high resolutions of model and product images together.
Since I had to move elements on the layout. Model and product images are in different layers in Indesign.
I used Indesign to combine those images together to create ads for magazine.
However, I was told  that it would be "SAFER" to combine those images together FRIST in photoshop.
he thinks the process should be that:
---Having a flated image of model and products in photoshop first
----then bring that one image in Indesign.
----This way it would insure the color will be right.
What do you guys think?
The places I worked in the past, has not done stuff like that.
I feel like ...colors aren't something we could control when magazine uses their own printing vendor.
What is your process to ensure the color is right when priting a combination of different high resolution tiff files?
Thank you very much for your time and knowleage.

Assuming you have some sort of color management in place, I would continue to do it the way you are.
But let's say you did want to follow this fellow's advice. Here's everything I can think of.
Putting the models and products together on one Photoshop "page" can wind up making the PSD file very big as there may be spaces between the models and products.
Never, ever flatten that Photoshop file. There's no need and makes a very complicated workflow if you have to make any changes.
You're right about the magazine printing process taking over color.
What are you sending the magazine? A PDF? There's totally no need to flatten in Photoshop then.
The art is flattened in it's own way.
I'm also assuming that your prducts and models are close to each other
