What kind of camera do professional photographers use?

I have never had a photoshoot done but it seems quite expensive. Price includes makeover. I have seen one shoot for £95 and plus the price you have to pay for photos. EXPENSIVE. Is it better just to buy a camera? We have a Nikon D90.

They use whatever camera gives them the results they need.

Professional looking photos has almost nothing to do with the camera, and almost everything to do with the skills and experience of the photographer.

You have to be joking! How much do YOU get paid for a day's work? The base price hardly makes anything at all for the photographer after overheads.

Yes, good quality equipment is expensive, but what you're paying for is expertise that takes years to develop. Well, unless you've hired one of the countless wannabes out there who also think the difference is in the camera. Search online for pro galleries then fetch your camera (or go hire a D4) and see how close you can get to matching them.

In addition, a skilled make-up artist is every bit as valuable (my business partner trained as one for this purpose). However, as I have seen some of these makeover / portrait services employing misleading marketing methods, I would suggest making certain you know what you're getting for your money. It is quite normal for prints to be exclusively supplied, and this may be a significant proportion of the total charge, but these charges should be clear before you sign or pay anything.

This question is extremely ignorant. A professional photographer spends their entire life perfecting their craft. It's a lifetime of passionate work that is driven by a desire to perfect their artwork, something that can never really be achieved. They spend money not only on education, sometimes training for 3-5 years to get a diploma, but once they are done they usually assist with established professional photographers to get their foot in the door and also learn from them. They usually take YEARS sometimes even decades before they even open up shop (the good ones anyway) all just to learn HOW to take a photo. Once they have a studio, which normally costs hundreds of thousands of dollars, they have to spend money on studio lighting, insurance, etc etc plus they have to eat and pay off that mortgage as well. Then we're talking about the quality of the camera used in the studio? Well if it's a REPUTABLE studio they're probably using a medium format system, which, and I'm not joking, can cost hundreds of thousands of dollars, operated by a professional with probably at least a decade of experience behind them.
Still think 95 pounds is expensive?

If you don't believe that photography is really that hard, and it mostly depends on the camera, then Please FOR THE LOVE OF GOD go and rent a Nikon D800 and a 24-70 2.8 lens which is the bare minimum even the worst of studios would try to get away with (a one day rental will probably run over 95 pounds) and then try to take the photos yourself. The quality of photos that you take will be an epic fail and you will be left wondering why the camera I told you to get wasn't good enough. Or maybe you'll learn something I don't know. But please, understand, photography as a profession is not a walk in the park, and it is not about how much money you've spent on your camera.
