.htaccess redirection to directories depends on URL - apache

Question

1) I have such directory structure:
.htaccess
album/
index.php
web/
.htaccess
index.php
...
...
In 'album' there is a gallery page and in 'web' there is a WordPress page.
How to fill .htaccess (I suppose in root dir) to redirect addresses depends on what is in URL:
www.domain.org -> goto /web and display wordpress page
www.domain.org/album -> goto /album and display gallery page
I've tried such thing in root .htaccess but without success (there is constant redirection to domain.org/web):
RewriteEngine On
ReWriteCond %{HTTP_HOST} ^(www\.)?domain\.org$ [NC]
ReWriteRule ^(.*)$ /web
ReWriteCond %{HTTP_HOST} ^(www\.)?domain\.org/album$ [NC]
ReWriteRule ^(.*)$ /album [L]
.htaccess in web directory is default of WordPress:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /web
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
How to solve this riddle?
Regards.

One of possible answer to thequestion (
RewriteEngine On
ReWriteCond %{HTTP_HOST} ^(www\.)?domain\.org$ [NC]
ReWriteRule ^album(.*)$ album$1 [L]
ReWriteCond %{HTTP_HOST} ^(www\.)?domain\.org$ [NC]
ReWriteRule web/$1 [L]
Weard is last line of this code. There are two spaces. I suppose first space means "empty string". This is strange (and also bad coding) however it works and I have enough of those redirections.

Answer 1

You can use these rules in root .htaccess:
RewriteEngine On
ReWriteCond %{HTTP_HOST} ^(www\.)?domain\.org$ [NC]
ReWriteRule ^((?!album).*)$ web/$1 [L,NC]
