You can own all the big white lenses you want but it comes down to earning a good reputation and if you don't have that then you will not get the big bucks. You don't get that with fancy equipment.
Look up Positionable Mounting Adhesive 568 and get the size you need for your photo, this is the best for mounting photos. Next be sure to get acid free foam board, do not use regular foam board. Roll out the mounting adhesive on a clean surface with Adhesive side up and trim off the roll larger that the photo you want to mount, wearing cloth gloves lay your photo backside down on the adhesive rolling it from one end to the other, try not to get air bubbles under the photo. Trim off the roll excess using sharp box knife and straight edge laying wax paper on the Adhesive so your straight edge will not stick to it. After it's trimmed turn photo face down on clean smooth surface that will not scratch your image then burnish down the Mounting Adhesive. Lay foam board down make sure it's larger than your photo by a few inches, peel off the backing of the mounting Adhesive and save it, then carefully lay it in the center of the foam board lightly so if you need to reposition it you can, after you have the photo where you want it lay the backing that you saved on top the photo and burnish it down. Take your box knife and trim the foam board up to the edge of your photo. You can also have glass cut to size of photo and have the edges of the glass smoothed so it will not cut you and use swiss clips to mount the glass on top your photo and it make a great display without a frame.
I have a small studio in my basement and am a retired graphic artist.
I started with a Canon F1 in 1971 but changed to nikon because there new cameras could use the old lenses and I can buy them on ebay for cheap. Both are good cameras but for travel I like something small so I'm using a Fujifilm X-E1 and this little gem takes great pics and is easy to carry around. Fuji also makes some great glass as well and is still made in Japan not China or Thailand.
