There is a distinct difference between the types of modelling required for a photo shoot than for the type needed for a catwalk show. Although it is likely you may be asked to do both kinds in your career, most models specialise in either one or the other, due to the specific requirements needed for each one. Most models are more suited to one than the other; so it is worthwhile to determine which one you are most suited to, and try and focus your efforts in applying for those types of jobs.
To be a catwalk model it is imperative that you have long, sleek legs, an elegant neck, good posture, stance and gait, and that you are able to walk and pose well. Catwalk shows are nearly always used for modelling clothes, so therefore you must have an excellent figure for modelling clothes, and a perfect shape to fit the standard sizes produced, which tend to be very small. You must also be able to change clothes quickly during shows, and present a variety of different looks within a very short space of time.
You will have many people working on you a once changing your look for various parts of the show, and the atmosphere backstage at a fashion show is always continually one of high pressure and intensity, so you have to be willing and able to work under these conditions. Fashion shows also require preparation and rehearsals, so you have to be willing to devote a lot of time and energy in being a catwalk model.
Photo shoots may be for modelling clothes as catwalk shows are, but they may also be for beauty products, hair products, makeup or many other commodities, and you must be adaptable and able to move between genres and present anything you are asked to model well. Although there is more time available for hair and makeup to develop a specific look, you must still be able to take a wide variety of looks, in order to give the client what they want.
To be a photo shoot model it is imperative that you can create a wide range of facial movements and poses, that you can take focused direction from the photographer and apply it, and that you are able to promote the product appropriately. More attention will be paid to your face in photo shoots than in catwalk modelling, as your face will be in close-up on them. Therefore you must have excellent skin, facial symmetry, and grooming to be a photo-shoot model.
Decide which of these traits you have more of through a critical analysis of your look and personality, and therefore which type of modelling you are best suited to, and focus on that type of modelling in particular. However, it is unquestionable that both types of modelling are tiring, stressful and demanding, but with the right determination, drive, and knowledge about which type of modelling you suit best, modelling can be a very interesting and rewarding career.
