- Dear Dwight, Aaron and Sean,
It’s Damo again with a question about camera sensors. I was doing some research into 50mm prime lenses when someone mentioned that a 50mm lens will really be 80mm on a cropped sensor. I use a Canon 1000D (Rebel XS), which uses a cropped sensor and was wondering what that really means and what effect that has on the quality and characteristics of the photos.
Look at Crop Factor like this: you draw a picture that is 8inx11in, and label that a 35mm. Now, your camera’s sensor might be 28mm, so let’s cut off an inch on each side, making it 6inx9in. Now using the power of imagineation we will make the measurement of this cut image back up to 8inx10in, but the same image, the cut one, will be represented. It would appear like you zoomed in a bit extra on the image. That is the effect a crop sensor has. The lens expects and is measured for 35mm, but yours might be 28, so the ‘zoom’ is a bit extra. Ironically, to diverge from this point, many lenses that fit crop factor cameras, can’t work on full frame sensor cameras. I
- As a person who wants to model for photographers, do I need to consider the possibility I will need to pose nude or semi nude? Oh boy, this is a touchy subject, and can get very grabby if handled wrong. First, no one can force you to take your clothes off legally for a photo. A photographer who demands it gives you two choices. Refuse or do so. One who does not clarify explicitly what the photos will entail, or deviates from it and asks you to remove clothes, should be fled from. Any truly worthwhile photographer seeking to do nude photyo shoots will be very up front with the model, and let you know.
Additionally, we recommend both for the model and the photographer that there be a model release and a very honest and detailed discussion before the shoot about what you each will be expected to do. If you don’t want to do nude or semi nude, don’t do them, but don’t mislead a photographer that wants to shoot those that you will, or will just earn the bad blood of a photographer. If you want a great place to meet photographers(or models to shoot, photogs), Dwight recommends Model Mayhem(Dwight’s profile). There are plenty of models on there who do not do nude shoots, and plenty of photographers more than happy to just do clothed shoots. There are some that go the other way as well, so be sure to note this when looking at profiles.
You can consider getting an agent, but you will likely need a sizable portfolio before you will find one who will best represent you, so take advantage of the many photographers(and models) willing to shoot for copies on CD or prints. You might get a few paid gigs, models, but for the first while you might need to smile for free to build your portfolio. When you have a plentiful portfolio you can then look into some model agencies and see what the requirements are, but don’t sign anything from them withou a long look of the papers by a lawyer to get a good grasp of the details.
