Here's how to handle photostream in the husband/wife situation
You have set up iCloud wrong in the husband/wife situation, for a couple of reasons (not just photostream). My wife and I both have ipads and iphones. Here's how to handle that.
1. Use a shared iTunes account (so you can both seamlessly use the same apps, etc. and not pay for them twice). If you want, set to download apps/music automatically. Even if your wife downloads an app you don't use which appears on your device, it takes 2 seconds to delete and it doesn't come back on your devices unless you want it to.
2. Each of you have SEPARATE iCloud accounts/apple IDs. So when you set up iCloud on your apple devices, you enter husband email and password. She enters wife email and password. Do NOT use the itunes shared account apple ID for this. So each of you create new Apple IDs, just for iCloud account use.
Now, you don't get her pictures on photostream and she won't get yours. And, better yet, you are NOT sharing the 5 GBs of free iCloud storage anymore. You have 5GBs and she has her own 5 GBs. Nor will you mix up her work contacts or calendars or reminders with yours. Best to always keep iCloud accounts INDIVIDUAL.
-- note that you need to delete your iCloud accounts that currently exist on your devices in order to do this. Don't worry. It sounds scary deleting the account (big red bar at bottom of iCloud settings), but you wont lose any data. --
One extra tip on this setup, if desired. Turn OFF find my iPhone in your newly created separate husband and wife iCloud accounts. Then set up a new iCloud account on your device (and hers), this time where both of you are using the shared iTunes account. However, make sure to turn OFF, mail, contacts, calendars, reminders, safari and notes on this account's settings. Only turn ON Find my iPhone. I change the description of this account from "iCloud" to "Find iPhone".
This will allow you to see all of your devices (including hers) from the one Find My iphone account. Otherwise, you will only see your devices and she will only she hers.
In sum, under settings/Mail,Contacts,Calendars, I have:
1. an iCloud account (all mine, not shared)
2. a "find my iPhone" account (renamed from iCloud) -- using shared iTunes Apple Id
3. My regular email accounts
Under Settings/Itunes & App Stores I have the shared Apple ID set up. I have Music, Apps and Books set to automatic downloads (this is optional).
Never use it. I don't want the pics my wife shoots on my devices and vice versa. Also I don't need to keep many of the pics I shoot. They are for temporary use. Not to mention it can be a data hog.
