Wa `alaykum As-Salamu waRahmatullahi wa Barakatuh.

You ought to choose whichever of these two areas you can excel and render service to the community.

Just selecting a field of study solely for making money is not desirable in Islam. Islam teaches us to excel in whatever we set out to do in life. So, if you choose to become a doctor, you should try to excel in it. However, you may not be able to do so if you have no interest in it. We should love what we do.

Journalism is a good area of study to pursue although it may not be very promising as far job opportunities are concerned.

As for photography, let me cite here one of my earlier answers:

“Photography as a medium of communication or for the simple, innocent retention of memories without the taint of reverence/shirk does not fall under the category of forbidden Tasweer.

One finds a number of traditions from the Prophet, peace and blessings be upon him, condemning people who make Tasweer, which denotes painting or carving images or statues. It was closely associated with paganism or shirk. People were in the habit of carving images and statues for the sake of worship. Islam, therefore, declared Tasweer forbidden because of its close association with shirk (association of partners with Allah). One of the stated principles of usul-u-Fiqh (Principles of Islamic Jurisprudence) is that if anything directly leads to haram, it is likewise haram. In other words, Tasweer was forbidden precisely for the reason that it was a means leading to shirk.

The function of photography today does not fall under the above category. Even some of the scholars who had been once vehemently opposed to photography under the pretext that it was a form of forbidden Tasweer have later changed their position on it – as they allow even for their own pictures to be taken and published in newspapers, for videotaping lectures and for presentations; whereas in the past, they would only allow it in exceptional cases such as passports, drivers’ licenses, etc. The change in their view of photography is based on their assessment of the role of photography.

Having said this, one must add a word of caution: To take pictures of leaders and heroes and hang them on the walls may not belong to the same category of permission. This may give rise to a feeling of reverence and hero worship, which was precisely the main thrust of the prohibition of Tasweer. Therefore, one cannot make an unqualified statement to the effect that all photography is halal. It all depends on the use and function of it. If it is for educational purpose and has not been tainted with the motive of reverence and hero worship, there is nothing in the sources to prohibit it.”

Almighty Allah knows best.
