My job involves frequently importing Photoshop edited Model Images into Corel.
My question is while importing which format is better .psd or .JPEG?
Also I want to keep the file size as least as possible (with 300 dpi image ofcourse)
I have noted that if I import .psd format image the Corel file becomes larger in size but when I save it in .pdf the file size reduces
Alternatively if i import .jpeg format image the Corel file becomes smaller in size but when I save it in .pdf the file size increases (Strange!!!)
Why is it so??? Also wanna know which of the two format is better if I have to send Print Magazine Ads to the agency??

OK, first step: understand that there's 2 types of compression: lossless and lossy .
When you bring a bitmap into coreldraw, if it's not a linked image (almost no-one uses linked feature), your tif, psd, jpeg, gif, etc are converted to CorelDRAW's internal lossless format. When that image is saved inside the Master CDR, it's similar to ZIP compression.
When exported from your master CorelDRAW file as PDF later, your PDF can be tiny... or huge. You decide the quality of the PDF. In the PDF engine, your choices for bitmap handling include:
How much editing do you need to do?
Files can be smaller in CDR or PDF if you import large PSD files as the PSD file format is not very efficient, unlike the CPT file format.
Another things about PSD's.. it's a file format that can easily have things like Adjustments Layers, Layer Styles, and other Photoshop-required effects inside. That means the PSD imported into CorelDRAW will look nothing like it's supposed to. If the PSD is "flattened" then it can be OK, but I always send a proof back anyway. Compare the difference on a little test:
