I think your i camera/phone did great as did the photographer. You went to Venice with out your DSLR I just sold my Sony A7 IV and lenses etc. I strictly use my Samsung S23 ultra for everything I shoot and have not been sorry. Check out photoshop and Topaz if you want to add size. They both do an excellent job. As for exposure adjustment if you shoot in raw with the samsung you can adjust everything the same as with a camera. You got great results can not wait to see more from your trip.

First, you appear a bit foolish, but a simple solution based on knowing where you are. On the Hog there is a sub forum that deals with photographs of women with few or no clothing, the nude forum. In addition, there is a sub forum for portraiture. So move this discussion (re-post) to either of these forums.

Next, there is an old rule in England that states, you can't get a job until you have a job and you will only get a job if you have already had a job. Silly, but it is about understanding the 'business' that you want to be in. So, where do you find models, why other women (mostly models).

Where will you find models? A place called Model Mayhem is a good start. You can join for free and you will need to build two things, a portfolio and more importantly, a reputation.

Oh, don't expect to just go on MM and find models, mostly you will fail. Remember, to find models you need a model to help you get to models. It is as simple as that.

On MM you will find what are called traveling models, that will be were you start. Models know models, so you turn to these models to get to be 'known' as a person doing photography. This is where the reputation part become critical. A recommendation from another model that you are 'kool' is what you need. It is also helpful to have known models giving out recommendations.

Now, you may not know this (surprise!) but you are close to the southern avenue traveled by models, especially in the winter. Next, you are in close proximity to Texas, don't laugh, it is central to the photographic world in general. Dallas /Fort Worth is quite close to Tulsa, and the other two are Houston and Austin Texas. Models are going through and using these Texas locations.

So, on Model Mayhem you will find Liz Ashley, hire Liz and get the portfolio started (she is considered one of the Grand Dams of internet modeling). Yes, MM is a pain to use, so you Google Liz Ashly and it will give you the link to her on line MM profile so you can get right to her IF you have a MM profile.

Right now there is another model traveling in the area Charlie Kristen, she has been around a number of years and does the traveling model circuit. She is a good model to get hooked up with, but your vary best would be Liz Ashley, she knows and net works with all the quality models. Just Google Liz Ashley and select 'images. Be in be sure to plug in Liz Ashley, nude and the hit images. Liz can do nudes, fashion and everything in between. She is also great to work with new photographers. Funny thing, she knows more about lighting and studio practices than your average photographer and she is a true female, vary nurturing.

Talk to the models and get started, and have fun.

Suggest you get your "credentials" in order first, if you haven't done it already. What is your business/studio name?
How do people find you? Check with Tulsa City Hall and learn if you need a license as a professional photographer. Get a business license and probably a state sales and use #. Use these to get items for your business without local sales tax. Print some business cards with business name, your name, address, email address, online place where you have posted photos that others might see, phone number (make it look professional).

Next, always appear professional and act like one. Think it through first - what will you say to introduce yourself to a stranger. Ask if he/she has been photographed, if they need more shots for their portfolio, etc.

Think now about where you can go to take a few test shots regardless of the weather or time of day. Or agree to an appointment to meet.

Research, research, research. You can do a lot online. I've been amazed at the photo pros with postings on youtube about lighting, posing, cameras/lenses, etc. Look for poses and lighting that you want to replicate in your shots/portfolio.

Best.

I am a very non-technical person and struggle with technology every day. After more than 20 years of photography and not buying a program over the internet I finally decided to go for Topaz after reading so many glowing reports here about what it can do. I've spent most of the morning trying to download files and I think I succeeded but I can't tell. Topaz has no phone tech support so I sent them an e-mail from their support page and received a response that they are swamped with requests and will e-mail me back in a few days. I have never bought programs from the internet because I was afraid I wouldn't be able to download or find them and I have fallen into exactly that trap. It's not a mistake I'll make again. I'll see what their response is, if one comes, but it looks like I've lost my money. Selling software and not offering accessible support is really shady. They will never understand my disappointment and frustration. I'll probably get a ton of snarky answers from hoggers who understand software but that will not be a help.
