I don't know which to buy.What is the difference between the 'Photography'Bundle and just Photoshop?

This is an example of what happens in a monopoly where a single entity corners the market. Adobe hasn't had any real competition to photo editing in decades and releases pointless bloatware as a result. I didn't want "creative cloud" nor "lightroom" but was forced to install both just to get to basic photoshop for $10/mo. Good grief. Sloppy business model meant to create confusion like Microsoft back in the day. Adobe has emulated Microsoft's failed strategy from the 90s.

Photoshop is the same! The Photograpy Plan has Lightroom Classic (and the here useless Lightroom) in addition. It's use is for photographers, but if Photoshop is the app you are interested in use that plan.

Difference: Photoshop alone provides 100 Gb of cloud space against only 20Gb for the Photographer's plan. 

The Photoshop plan is also available on a monthly basis. The Phot..Plan is available on a yearly basis only. 

As mentioned, the Photography plan is what you want. If you want more cloud space take the 1Tb option. But it's not necessarily needed.

Hi

I have tried to show a comparison below – but also make it clear the commitment (the prices are UK but you will be able to look up the prices for your country).

The Photography plan

£9.98 per month comes with Photoshop, Lightroom and PS for ipad, Spark and Portfolio and has 20GB cloud storage storage

£19.97 per month comes with Photoshop, Lightroom and PS for ipad, Spark and Portfolio and has  1TB cloud storage storage

In both the above the commitment is to an annual plan paid for monthly (cancellation before the year invokes cancellation charges)

Photoshop plans

£19.97 per month comes with Photoshop (no Lightroom) and PS for ipad, Spark and Portfolio plus Fresco and  has 100GB cloud storage

The commitment is to an annual plan paid for monthly (cancellation before the year ends invokes cancellation charges)

£238/42 per year – same as above but paid annually

£30.34 / month comes with Photoshop (no Lightroom) and PS for ipad, Spark and Portfolio plus Fresco and  has 100GB cloud storage  This is a monthly plan – with no commitment to 12 months.

The Photoshop version is the same in the standalone and Photography plan, which gives remarkable value to many users.

Photoshop app is exactly the same in bundle and when buying standalone app. Exactly the same! I believe that is what interests you most. Why prices are different? Adobe wants photographers to use Lightroom and Photoshop and they offered excellent price in bundle package below any expected price, even below real value. Why someone wants to buy only Photoshop? I do not know, there are some ridiculous pricing methods with Nescaffe which also does not have any sense and I was wondering for years why but people were still buying 200 grams which costs 2,3X of 100 grams.
