Raise the back of your tongue to touch the soft palate (velum). Stop the air, then release.

Americans pronounce cameras as KA-muh-ruhz (/ˈkæmərəz/). In "cameras", the "a" vowel before M or N raises and fronts toward [eə] — the tongue pulls up and forward, breaking the vowel into a tense glide as it anticipates the nasal. This is called the Cat-Vowel Before M/N, a hallmark of natural-sounding American speech. It comes out as KA·muh·ruhz. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "He checked the security cameras to identify the perpetrator" or "The department is implementing body cameras for all officers" — more examples below.

Raise the back of your tongue to touch the soft palate (velum). Stop the air, then release.

The tongue relaxes down in the back and the corners of the lips relax before the consonant. This adds a schwa-like 'uh' relaxation after the /æ/. Think of it as 'relaxing out of the vowel' — it is no longer a pure /æ/ sound.

The schwa before R disappears — R becomes the vowel of the syllable. This is the 'er' sound without a distinct vowel before it.

Relax your lips, jaw, and tongue completely. Drop your jaw slightly and keep the tongue neutral.
Same position as S, but add vocal cord vibration. Feel the buzz.

The textbook way isn't wrong — it's just not how anyone actually says it.
In "cameras", the "a" vowel before M or N raises and fronts toward [eə] — the tongue pulls up and forward, breaking the vowel into a tense glide as it anticipates the nasal. The "/æ/" vowel raises and fronts before M or N — tongue pulls up and forward, producing a tense [eə] glide (between /e/ and /ə/). Not a pure /æ/.
Stress falls on the first syllable, not the others. Stretch KA — keep everything else short and quick.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
